  • Concentrated Solar Radiation Simulation For Space Solar Power Module
           Vacuum Testing
    • Abstract: Space Solar Power (SSP) is broadly defined as the collection of solar energy in space and its wireless transmission for use on Earth. The implementation of such a system could offer energy security, environmental, and technological advantages. The Integrated Symmetrical Concentrator (ISC) and Modular Symmetrical Concentrator (MSC) concepts have received considerable attention among recent commonly proposed SSP implementations. Each concept employs an array of modules for performing conversion of concentrated sunlight into microwaves for transmission to Earth. Until the efforts of the U.S. Naval Research Laboratory, no module prototypes had been subjected to the challenging conditions inherent to the space environment. The customized space simulation testing and the associated development described in this paper detail the efforts to test a prototype module in vacuum under multiple suns of solar concentration. A small vacuum chamber and 4000W Xenon light source were adapted to provide the desired test conditions. In particular, much effort was devoted to arriving at an effective, inexpensive solution that was consistent with the budget constraints of the project without compromising the fidelity and relevance of the tests.

  • Selecting the Best ALT
    • Abstract: Throughout the many years of accelerated life testing (ALT) development, colleagues have found numerous ways to take advantage of the interaction of stress and failure mechanisms.[1-14] In an ideal situation, the reliability engineer will have ample time, samples, test resources, and knowledge to conduct ALT. However, this is often not the case. Trading off the risks in conducting ALT and meeting the myriad constraints and expectations is a challenge. Understanding the basics of ALT approaches and associated assumptions permits test designers to select the ALT method that will provide meaningful results in time for technical and business decisions while meeting budgetary and risk-tolerance limits. There is no single way to design ALT for a specific set of conditions, but clearly articulating the tradeoffs involved permits the entire design team to fully understand the test results. The "best" ALT is a method that adds value to the design process. The most accurate results would involve testing all the production units in customer use until all units have failed. Although this is clearly not practical, neither is the simple-minded approach of guessing at the results. In between these two extremes lies an optimal approach: the most efficient ALT that provides meaningful results. When the results provide information to make design or program decisions, ALT adds value. Reducing ALT costs by reducing sample size or test duration is possible, but doing so may significantly increase uncertainty of the results. Running the test longer to achieve more accurate results is often constrained by the timeline to make decisions. Such tradeoffs force reliability engineers to carefully design each ALT and determine the best path forward.

  • Contamination of Ultra-High-Purity (UHP) Gas Distribution Systems by Back
           Diffusion of Impurities
    • Abstract: A combination of experimental investigation and process simulation was used to analyze the effect of various operational parameters on impurity back diffusion into ultra-high-purity (UHP) gas distribution systems. The process model developed in this work was validated by comparing its predictions with data from the experimental test bed. Surface diffusion as well as convection and dispersion in the bulk fluid played a strong role in the transport of moisture from vents and lateral branches into the main line. Parametric studies on the effect of key operational and design parameters were performed experimentally and with the application of a process simulator. In this analysis, a dimensionless number (Peclet Number) was derived and applied as the key indicator of the relative significance of various transport mechanisms in moisture back diffusion. Guidelines and critical values of Peclet Number were identified for assuring the operating conditions meet the purity requirements at the point of use while minimizing UHP gas usage. These guidelines allowed the determination of lateral lengths, lateral diameters, flow rates, and restrictive flow device configurations to minimize contamination.

  • Anatomy of a HALT
    • Abstract: A Highly Accelerated Life Test (HALT) consists of much more than simply subjecting a product to extreme environments to discern potential design weaknesses. Before testing, careful attention must be paid to planning, hardware and equipment availability, and ensuring the appropriate personnel are involved. The test must also include reviews of any potential hardware failures and the procedure for handling them. After test completion, a report must be written to document the entire procedure and any lessons learned. This article covers the entire anatomy of a HALT test from inception to final report.

  • Discrepancies Caused by Common Industry Standard Practices Part 1:
           Environment Specification
    • Abstract: Industry standard practices lead to discrepancies in the severity of flight and test environments. Steps in common processes defined in guidance documents are based upon assumptions and simplifications not always evident. Not acknowledging these assumptions leads to non-flight like environments in test and analysis. Documents such as MIL-STD-1540, NASA-HDBK-7005, and MIL-STD-810 all provided valuable guidance but should not be applied without consideration of underlying assumptions and simplifications. Hypothetical examples, based on real experiences, will be reviewed to illustrate the importance of understanding, modifying, or eliminating the assumptions and simplifications. The examples provided are primarily random vibration environments but the messages also apply to other dynamic environments including shock and acoustics. This paper is separated into two parts. The first addresses environment specification. The second addresses qualification and acceptance test requirements.

  • Minimum Input Trace for Multiple Input Multiple Output Linear Systems
    • Abstract: Specification of the cross spectra for a multiple-input/multiple-output (MIMO) vibration test is challenging. This paper presents a method for tests where the specifications of the output (the control points) autospectra are available. The autospectra of the outputs are specified and cross spectra between the outputs are derived that will minimize the trace of the autospectra of the inputs (the drive signals) with the constraint that the input spectral density matrix is positive definite. The hypothesis is that nature likes a minimum energy solution.

  • Evaluating Aerosol Transmission Efficiency in a Sampling System
    • Abstract: This work examines the physical factors that contribute to sampling errors in an aerosol sampling system consisting of a sampling probe and a sampling line. Aerosol particles are more massive than gas molecules and therefore tend to deviate from air streamlines in response to sudden directional change, which potentially leads to sampling errors during sample transfer processes. Based on well-established studies involving particle transport and deposition, an analysis was performed to determine the sampling line transmission efficiency for 0.5- and 5-μm particles as these particle sizes are used in defining air cleanliness level in ISO 14644-1[1] and FED-STD-209E.[2]* Our analytical results indicate that significant particle losses for 5-μm particles can occur if bends exist in the sampling lines. In addition, particle losses typically can be reduced by lowering the air velocity in the sampling line, and this can be achieved by using a sampling line with a larger inner diameter (I.D.). The example calculations also showed that 0.5-μm particles, with their insignificant inertia, have nearly 100% transmission efficiency regardless of the sampling line bends.

  • Highly Accelerated Life Test (HALT) Program at Space Systems Loral
    • Abstract: Highly Accelerated Life Testing (HALT) is used in the commercial electronics industry to improve product robustness prior to starting production. The basic theory is that testing well beyond expected, intended-use environments may uncover design flaws that could become field failures after a product is in production. By fixing issues prior to starting production, costly recalls can be avoided. HALT has proven to be effective, as evidenced by its wide incorporation in the commercial electronics industry. Could HALT also be worth the time and expense of performing on commercial satellite hardware, which is designed to rigorous standards and tested over military-grade environmental test specifications? This paper summarizes Space Systems/Loral's (SS/L) initial experience with HALT, experience over time, and refinement of the traditional HALT process with emphasis on finding the operating limit margins before purposely searching for any failure limits. The methodology used by SS/L has proven to be effective when introducing new technologies and complex designs for use on commercial satellites.

  • Evaluation of Vibration References with Equivalent Kurtosis and Dissimilar
           Amplitude Probability Densities
    • Abstract: The generation of Gaussian noise with a specific auto spectral density (ASD) is a well-documented process employed in drive signal generation in vibration control applications. In recent years, vibration control system vendors have introduced the ability to modify the probability density function (PDF) characteristics associated with the reference ASD, yielding a non-Gaussian drive. The specific parameter defining this process is kurtosis. This paper will discuss concerns with this practice in terms of synthesizing a time history with dissimilar PDF characteristics to that of the measured data upon which the original ASD and kurtosis characteristics were based. An example is discussed from both statistical and fatigue perspectives.

  • Laboratory Staff Evaluation Process
    • Abstract: Objectively evaluating laboratory staff is a very difficult task. Variations in supported equipment, student performance, and process sensitivity prevent the use of direct, objective criteria in employee performance measurement. These factors are multiplied in research facilities, where equipment uptime and process performance measurements are not easily determined. Supervisors, therefore, must apply more subjective techniques in staff evaluation, which often results in the perception of inequity. This paper presents a rigorous evaluation process that utilizes significant employee participation to address this issue of perceived inequity.The process utilizes five areas of evaluation: Goals and Accountability; Job Performance; Individual Characteristics; Aspirations and Assistance; and Employee Feedback. These areas, applied through an employee self-evaluation followed by direct interaction between employee and supervisor, serve as discussion points as well as a means of performance documentation. While still primarily subjective in nature, the process significantly reduces any perception of unfairness and allows the employee to document issues for future reference. Introduced six years ago at the Birck Nanotechnology Center at Purdue University, the process has undergone numerous tweaks and enhancements leading to the version documented in this paper.

  • Evaluating Aerosol Aspiration Efficiency in Fast-moving Air
    • Abstract: Sampling representative aerosol particles in fast-moving air is a challenging task. Aerosols are significantly more massive than gas molecules, thus they might not follow air streamlines well and could be more easily subjected to sampling errors. This work examines the physical factors that govern the aspiration efficiency of an aerosol sampling probe in unidirectional moving air, and explores the plausible sampling deviations under various high air velocity scenarios. The particle sizes of 0.5 and 5 μm are of particular interest due to their use in defining air cleanliness levels in ISO 14644-1[1] and FED-STD-209.[2]* Our analytical results indicate that significant sampling errors could occur for 5-μm particles when a thick-walled sampling probe is used, or when the air velocity at the sampling probe inlet does not match the velocity of the incoming air (i.e., anisokinetic sampling). The aspiration efficiency of 0.5-μm particles, on the other hand, is nearly 100% due to sufficiently small inertia of these particles.

  • Financial and Operational Survey of 12 Major University Nanofabrication
           Facilities: A Benchmarking Study
    • Abstract: Efficiently running a major nanofabrication research user facility within the framework of a university is a daunting task. Operational costs, staffing, training, safety, and the diversity of the research, faculty, and users are but a few of the challenges facing the management team. This article reports on a subset of metrics used to characterize such user facilities, based on an extensive survey of 12 major university laboratories. Data relating to such factors as laboratory staffing, operating costs, subsidies, cost recovery, tuition, comparative tool rates, hours of use, and populations are summarized and reported on in the context of determining a reasonable measure of an efficient laboratory operation.

  • Case Study: Design and Construction of the Draper Laboratory
           Microfabrication Center
    • Abstract: For 25 years, Draper Laboratory has been active in the areas of microelectromechanical systems (MEMS) and multichip modules (MCM), using two separate laboratories. When these laboratories were constructed, cleanroom technology was in its mid-life cycle. To meet evolving R&D needs, the cleanroom facilities recently underwent a major renovation as described in this article.

  • Do You Know that Your Accelerated Vibration Test Requirement Is
           Correct'
    • Abstract: Vibration test time-compression methods have existed for decades and are well-documented. However, not all practitioners are aware of how these methods were developed and the proper utilization of the developed theory. While many sources have attempted to clarify the methodology, there is confusion on many points. The objective of this paper is to help new vibration test engineers understand accelerated testing theory and practice. The lab is a valuable training ground, but sometimes the subtleties are not communicated. A more complete understanding of the theory and practice of vibration test time-compression methods is needed when translating contract requirements into test procedures used in product development and validation.
