Phase Ref. System Overview

  • Provide high stability, low noise 1300MHz reference to synchronize RF and Laser systems
  • Phase reference line (PRL) runs first 700m of LINAC
  • Also provide LO reference (1320MHz, 3920MHz) to LLRF chassis (separate distribution)
  • Long haul reference to experimental laser systems 4km away
  • Master timing source for LCLS-I (eventually); 476MHz to Main Drive Line (LCLS-I,FACET)
  • Lock/resync generated frequencies at 71.43kHz (1300MHz/18200), common subharmonic
