Simcon 2.1
DESY FPGA SIMulator and CONtroller Overview
Ruben Carcagno - 5/3/2005
Simcon 2.1
• First FPGA-based LLRF controller used at FNAL for a SCRF cavity– Developed at DESY and used in the single
cavity “CHECHIA” horizontal test stand– One Simcon 2.1 system was delivered to
FNAL in March 2005 and used already to run the A0 photoinjector 1.3 GHz TESLA Cavity
– Includes a real-time cavity simulator with beam loading and mechanical detuning effects
