A 96 channel receiver for the ILCTA LLRF system at fermilab
TL;DR: In this article, a down-converter chassis is developed that contains 12 eight-channel analog modules and a single up-convolutional module for ILC main LINAC RF station with 26 nine cell cavities driven from one klystron.
Proceedings ArticleDOI
Multichannel vector field control module for LLRF control of superconducting cavities
Philip Varghese,Brian Chase,B. Barnes,J. Branlard,P.W. Joireman,Daniel Klepec,U. Mavric,V. Tupikov +7 more
TL;DR: The MFC (Multichannel Field Control) module is a 33- channel, FPGA based down-conversion and signal processing board in a single VXI slot, with 4 channels of high speed DAC outputs, which provides additional computational and control capability for calibration and implementation of more complex control algorithms.
