Commissioning and Performance of Beam Diagnostics in the FACET-II Beam Spectrometer | ||||
|
|||||
Funding: Work supported in part by the U.S. Department of Energy under contract number DE-AC02-76SF00515. The FACET-II facility has begun beam delivery to the experimental user area and the suite of instrumentation in the spectrometer beamline following the experimental area is currently being commissioned. The performance of these diagnostics systems will be described, including the single shot "butterfly" emittance diagnostic that will be key to demonstrating emittance preservation of mm-mrad emittances in plasma wakefield acceleration experiments. Additionally, the gamma ray diagnostics will be discussed that will be used to assess the beam dynamics of low emittance beams in plasmas and to characterize beam-plasma filamentation instabilities. |
