  • Thin head atomic force microscope for integration with optical microscope

      Authors: Nianhang Lu, Shasha Xiao, Rui Zhang, Jirui Liu, Long Ma, Sen Wu
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      We present a novel thin head atomic force microscope (AFM) that can be easily integrated with an upright optical microscope (OM). The optical beam detection unit in the AFM used an obliquely incident laser beam onto the cantilever, reducing the AFM head’s effective thickness to 7.3 mm. That allows an open space above the cantilever probe to accommodate the objective lens up to 0.6 numerical aperture (N.A.) without obstruction. A multi-function digital controller was developed to control the AFM and reserved interfaces to communicate with the OM. To assess the performance of the developed AFM, we first measured the noise level and bandwidths of the AFM system. Then, the imaging quality of the AFM was evaluated by both calibration grids and two-dimensional materials. Finally, the thin head AFM was integrated into a homemade white light interferometer as a demonstration of combined use with an advanced optical system. The experimental results demonstrated that our developed AFM is suitable for integration under upright OM and brings AFM high-resolution advantages to the existing OM system.

  • A Pockels cell enabled heterodyne phase contrast imaging diagnostic for

      Authors: A. Marinoni, C. P. Moeller, J. C. Rost, M. Porkolab, E. M. Edlund
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      This work describes a novel optical heterodyne detection scheme that significantly extends the frequency response of the phase contrast imaging method to detect electron density fluctuations in tens of megahertz frequency range. The system employs a variable frequency electro-optic modulator to allow operation at any frequency in the range 10–40 MHz without the need to realign the system. The frequency coverage of the system makes it suitable to measure the radial structure of the electron density component of ion cyclotron emission on devices having confining magnetic field of a few tesla, thus extending the purely temporal measurements provided so far by magnetic probes.

  • Convergent neutral gas injection using supersonic gas puffing (SSGP)
           method for propellant feeding system in RF electric propulsion

    • Free pre-print version: Loading...

      Authors: Takeru Furukawa, Yuichi Ishigami, Daisuke Kuwahara, Jyunichi Miyazawa, Shunjiro Shinohara
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      A convergent gas feeding method is proposed to alleviate neutral gas depletion near the central plasma region in typical electrodeless radio-frequency (RF)/helicon plasma thrusters. To achieve further performance improvement, the SuperSonic Gas Puffing (SSGP) system is one of the methods that is expected to overcome the above-mentioned depletion and the density limit. This study discovered that the spatiotemporal profiles of the neutral pressure and the estimated gas diffusion angle vary depending on the SSGP gas feeding condition, i.e., the nozzle size, filling pressure, and the valve opening time. Convergent gas feeding is successfully conducted using the SSGP method in a vacuum. As a preliminary study, high-density plasma is also obtained in the vicinity of the gas injection region using the developed SSGP system. The effects of the gas feeding position and an external divergent magnetic field on the plasma density are investigated. A suitable gas feeding position/region exists for plasma generation using the RF/helicon plasma thruster.

  • Statistical neural network (SNN) for predicting signal-to-noise ratio
           (SNR) from static parameters and its validation in 16-bit, 125-MSPS
           analog-to-digital converters (ADCs)

      Authors: Linjie Hou, Yvtao Liu, Weikun Xie, Zhijian Dai, Wanyv Yang, Yijiu Zhao
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      In the analog-to-digital converter (ADC) test process, the static and dynamic performance parameters are the most important, and the tests for these parameters account for the bulk of the ADC test cost. These two types of parameters follow certain relationships, which are incorporated into the ADC test to reduce the cost. In this paper, we focus on the signal-to-noise ratio (SNR), a key indicator of the dynamic performances of ADCs. A statistical neural network (SNN) with two hidden layers was constructed to predict the SNR from the feature variables, which were extracted from the static parameters. A 16-bit, 125-MSPS ADC was used to evaluate the proposed prediction model. Compared to the measured SNR obtained by traditional fast Fourier transform based test methods, the predicted value had a mean average error of only 0.75 dB. In addition, the Shapley additive explanations interpreter was adopted to analyze the feature dependences of the SNN model, and the results demonstrated that the deterioration of the integral nonlinearity-curve-related features could significantly decrease the SNR, which is consistent with previous research results. The reported results demonstrated that, at the cost of a slight loss of accuracy, the proposed SNN can significantly reduce the test complexity, avoid dynamic parameter measurements, and reduce the total test time by about 4%.

  • High sensitivity gas pressure sensor based on different inner diameter
           quartz capillary cascading and Vernier effect

    • Free pre-print version: Loading...

      Authors: Wenhao Ye, Chao Jiang, Xiaoshan Guo, Hailin Chen, Yuan Wang, Xiping Zhu, Simei Sun, Changning Liu
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      In this paper, a highly sensitive optical fiber gas pressure sensor is proposed and experimentally verified. The sensor is composed of two Fabry–Pérot (F-P) cavities, and two F-P cavities are fabricated by a single-mode fiber and two quartz capillaries with different inner diameters splicing. Among them, the small inner diameter capillary is used as a gas channel connecting the large inner diameter capillary and the external environment. The manufacturing process of the sensor only involves capillary cleaver and splicing and does not involve other complex manufacturing technologies. By correctly adjusting the length of the two quartz capillaries, when the free spectral range of the two F–P cavities is very close, the optical Vernier effect will be observed and used as a sensitive probe for detecting gas pressure. The experimental results show that, in the pressure range of 0–0.8 MPa, the gas pressure sensitivity of the sensor reaches −81.73 nm/MPa with a linearity of 99.7%, and the temperature cross-sensitivity is only 1.82 kPa/°C. Due to its easy manufacture, high sensitivity, compact structure, and small volume, the sensor has become one of the preferred structures for large-scale use in the field of gas sensing.

      Authors: Liangguo He, Kun Li, Yi Yan, Ziyang Cheng, Lei Xu, Xinyu Li, Xinfang Ge, Zengxiang Shan, Haotian Dou
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      A new multimodal bidirectional linear inertial impact motor with bidirectional motion based on self-clamping control driven by a single-harmonic signal was designed and manufactured. By applying driving signals of different resonant frequencies to the piezoelectric plate of a piezoelectric motor combined with the unique structural design of the motor, the piezoelectric motor has multiple modes and has the ability of two-way movement. First, the overall structure of the motor is introduced, and its working principle and theoretical displacement characteristics are presented through the periodic motion diagram of the piezoelectric motor. Second, the simulation analysis is carried out to determine the working modal of the proposed motor with COMSOL5.2. Finally, a motor prototype is developed, and the accuracy of the working principle and the simulation analysis is verified through experimental tests. When the motor has no load, the driving voltage is 200 Vp–p. The maximum speed when moving to the right reached 3.125 mm/s when the preload is 2 N, and the driving frequency is 96 Hz. The maximum speed when moving to the left reached 4.301 mm/s when the preload is 4 N, and the driving frequency is 148 Hz. In the load capacity test of the motor prototype, the maximum load of the piezoelectric motor prototype moving to the right and left can reach 0.4 and 0.6 N, respectively. Compared with similar inertial impact motors, the proposed motor achieves flexible control of driving and switching of two-way movement conveniently and has a certain driving ability.

  • The current–voltage measurements under flat-top pulsed magnetic fields
           for non-ohmic transport study

      Authors: Wenqi Wei, Ming Yang, Shimin Jin, Haipeng Zhu, Junfeng Wang, Xiaotao Han
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      Investigation of the non-ohmic transport behaviors under high magnetic fields can provide a new way to explore novel field-induced phenomena. We present the current–voltage measurements under high magnetic fields based on the flat-top pulsed magnetic field system. Two different measurement strategies were compared, given that the excitation current swept continuously or increased by a series of pulses. For the short duration of the flat-top pulsed field, the continuous current method was adopted and well optimized to reduce the Joule heating and achieve the quasi-static measurements. Finally, the non-ohmic behaviors of a quasi-one-dimensional charge density wave Li0.9Mo6O17 were successfully studied under the magnetic field up to 30 T at 4.2 K, which was the first current–voltage measurements carried out in pulsed magnetic fields.

  • A compound cantilever beam piezoelectric harvester based on wind energy
           excitation

      Authors: Zheng Zhang, Lipeng He, Renhui Hu, Dianbin Hu, Jianwen Zhou, Guangming Cheng
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      In this paper, a compound cantilever beam based piezoelectric energy harvester (CCBPH) is proposed. This piezoelectric energy harvester uses vibrations caused by vortex excitation behind the winding fluid to harvest wind energy. In particular, this structure uses vortex excitation formed behind a vertically suspended cylindrical winding fluid to cause the vibration of the cylindrical winding fluid, which then indirectly excites the piezoelectric element. The CCBPH consists of a fixed support, a cantilever beam, magnet-1 and magnet-2, a support beam, two piezoelectric units-PVDF (polyvinylidene fluoride), a compound cantilever beam, and a cylindrical winding fluid. We investigated the parameters affecting the structure and verify the effectiveness of the energy harvester through the design of the structure, simulation analysis, and experiments. The experimental results show that the CCBPH can obtain the maximum output voltage from the energy harvester at a wind speed of 18 m/s. The maximum output power was achieved with an external load resistance of 2000 kΩ. By comparison, it is found that the maximum output power is 0.095 mW when the distance between two magnets is 20 mm and the mass ratio is 1:2 for copper.

      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      We present a portable CO2 laser heating system for in situ x-ray absorption spectroscopy (XAS) studies at 16-BM-D (High Pressure Collaborative Access Team, Advanced Photon Source, Argonne National Laboratory). Back scattering optical measurements are made possible by the implementation of a Ge beamsplitter. Optical pyrometry is conducted in the near-infrared, and our temperature measurements are free of chromatic aberration due to the implementation of the peak-scaling method [A. Kavner and W. R. Panero, Phys. Earth Planet. Inter. 143–144, 527–539 (2004) and A. Kavner and C. Nugent, Rev. Sci. Instrum. 79, 024902 (2008)] and mode scrambling of the input signal. Laser power stabilization is established using electronic feedback, providing a steady power over second timescales [Childs et al., Rev. Sci. Instrum. 91, 103003 (2020)]—crucial for longer XAS collections. Examples of in situ high pressure–temperature extended x-ray absorption fine structure measurements of ZrO2 are presented to demonstrate this new capability.

      Authors: Pierre Lhuissier, Louis Hébrard, Xavier Bataillon, Pierre Lapouge, Frédéric Coste, Patrice Peyre, Elodie Boller, Jean-Jacques Blandin, Luc Salvo, Guilhem Martin
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      We describe our miniature laser powder bed fusion (L-PBF) system for in situ synchrotron x-ray micro-computed tomography (XCT) at the European Synchrotron Radiation Facility. This replicator was designed to extend the characterization of L-PBF to 3D. This instrument fills in a technical gap because the existing replicators were mostly designed to shed light on the dynamic mechanisms involved in molten pool formation but, therefore, suffered from a lack of 3D information. Technical details regarding the setup and beamline integration are given. Experimental validations via post-mortem XCT scans and in situ scans acquired during experiments conducted at the BM05 beamline of the European Synchrotron Radiation Facility are provided. Based on a few illustrative examples, we show that such a replicator opens the path to collect key 3D information that to date could not be available. Our miniature instrument complements the other replicators developed in the world by other research groups that enable operando x-ray imaging (radiography) and operando x-ray diffraction.

      Authors: Xin Yu, Haojie Xia, Weishi Li, Jin Zhang, Songtao Chang
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      It is difficult to improve the resolution and precision of a field-programmable gate array (FPGA)-based time-to-digital converter (TDC) in time interval measurement. In this study, we design a carry-look-ahead delay chain structure and integrate an interleaved sampling method with an online calibration and bin readjustment approach to implement a TDC. We take advantage of the adaptive logic module units applied in a Cyclone-10 GX (10CX220YF780E5G), which is a 20 nm low-power consumption and low-cost FPGA. In this new generation FPGA, we implemented a high-precision time interval measurement, which exceeded all our previous works with a 4.8 ps root-mean-square resolution and a 5.68 ps least-significant-bit resolution.

  • A four parallel laser-based simultaneous measurement method for
           6-degrees-of-freedom errors of rigid body with translational motion

      Authors: Guoqiang Fu, Yue Zheng, Sipei Zhu, Caijiang Lu, Xiaolei Deng, Luofeng Xie, Jixiang Yang
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      The measurement of six-degrees-of-freedom (6-DOF) errors of rigid bodies can show the real and accurate spatial pose of those rigid bodies. It plays a major role in precision calibration, spacecraft docking, machining, assembly, etc. In this paper, a four parallel laser-based simultaneous measurement (FPL-SM) method is proposed for measuring 6-DOF errors of rigid bodies with translational motion. First, a FPL-SM device is introduced. Its four laser heads form a rectangle, which is perpendicular to the movement direction of the measured linear displacement. Second, identification formulas for all geometrical errors in rigid bodies with translational motion are presented based on the relative positions of the four lasers. Based on the readings of the four lasers, angular errors and corresponding straightness errors are calculated for the direction of motion around the other two linear motions. As the two parallel sides of the rectangle are in different planes, the straightness errors of the two planes are different. The rolling angular error in the direction is expressed as the difference between the straightness errors of the two planes divided by the distance between the two planes. Six fundamental errors for rigid bodies with translational motion are obtained by four lasers in a single setting of the device. For multiple rigid bodies with mutually perpendicular translational motion, the squareness error is calculated by fitting to the actual direction of motion. Finally, experiments were carried out on the SmartCNC_DRDT five-axis machine tool and 21 geometric errors were determined for three translational axes. Error compensation was carried out using the generated machine tool geometric error data to verify the effectiveness of the proposed FPL-SM method. In addition, geometric errors and thermal errors of the Z axis of the GTI-2740 machine tool are measured based on the FPL-SM method.

  • The effect of copper grain size on laser ultrasonic backscattered signal

      Authors: Fengyi Zhang, Yanjie Zhang, Tao Wang, Wei Zhang, Pengfei Gong, Anmin Yin
      Abstract: Review of Scientific Instruments, Volume 93, Issue 8, August 2022.
      Grain size has an essential influence on the serviceability of metallic materials. In this paper, a noncontact laser ultrasonic testing platform is built to study the effect of copper grain size on the laser ultrasonic backscattered signal. According to the correlation between grain size and ultrasonic wavelength, the ultrasonic scattering by copper grains in the experiment contains not only Rayleigh scattering but also the transition region from Rayleigh scattering to stochastic scattering. Using time–frequency analysis, the influence of copper grain size on the characteristic parameters of backscattering was explored, and a prediction model of grain size was established, which was compared with the prediction model based on the attenuation method to verify the accuracy of the backscattering model. The results show that the backscattered signal can adequately characterize the grain size information and laser ultrasonics is a method that can realize on-line detection of grain size.
