Description
The LINAC Coherent Light Source requires an RF stability of 0.1% rms in
amplitude, 100 fs in phase for a 850 ns fill time for the S-band
structure, 125 fs in phase for a 100 ns fill time for the X-band
structure and 30 ns rise times for the RF gun pulse shaper. This paper
describes the design of a new VME/EPICS-based control system for the
LCLS low level RF system that will monitor and control the RF phase and
amplitude so that these requirements can be met with the use of beam
based feedback. The challenges with measurement of RF phase as seen by
the beam are also discussed.
