      Cavity-based x-ray free-electron lasers (CBXFEL) will allow the use of optical cavity feedback to support generation of fully coherent x-rays of high brilliance and stability by electrons in undulators. CBXFEL optical cavities comprise Bragg-reflecting flat crystal mirrors, which ensure x-rays circu…

  • Circular attractors as heating mechanism in coherent electron cooling

      First page: 054403
      Abstract: Author(s): S. Seletskiy, A. Fedotov, and D. Kayran
      We show that under certain conditions a longitudinal mismatch between an electron and a hadron beam in a coherent electron cooling (CeC) scheme creates a circular attractor in the longitudinal phase space of the cooled hadrons. Formation of an attractor completely stops the cooling and results in an…

      Abstract: Author(s): Yongjun Li and Robert Rainer
      For some synchrotron light source beamline applications, a round beam is preferable to a flat one. A conventional method of obtaining a round beam in an electron storage ring is to shift its tune close to a linear difference resonance. The linearly coupled beam dynamics is analyzed with perturbation…

      Abstract: Author(s): R. Singh and T. Reichert
      Longitudinal charge profile measurements or bunch shape measurements are a challenge for temporally short nonrelativistic bunches. The field profile has a larger longitudinal extent compared to the charge profile for such beams. This affects the ability of field sensing devices such as phase pickups...

      Abstract: Author(s): E. A. Schneidmiller
      Typically, in self-Amplified spontaneous emission free electron laser (SASE FEL) based short-pulse schemes, pulse duration is limited by FEL coherence time. For hard x-ray FELs, coherence time is in a few hundred attosecond range while for XUV and soft x-ray FELs it is in the femtosecond regime. In ...

      Abstract: Author(s): R. Joel England and Levi Schächter
      We examine through numerical calculation the collision of counter-propagating trains of optically spaced electron or positron microbunches in a 1 TeV collider scenario for a dielectric laser accelerator.
