In J-PARC, the accelerator systems are controlled using the master clock of 12 MHz made in Computer/Network Equipment Room (CER) of the central control building. The low-level radio frequency (LLRF) system of LINAC is based on the reference signal of 312 MHz synchronized with the 12 MHz clock. The reference signal was made by a module, which is called “RF&CLK board”, in the upstream part of...

A 1.3 GHz phase averaging reference line is being developed for Fermilab’s NML accelerator. The reference line is composed of directional couplers and 7/8” cable. The reference line is shorted at one end of the line to provide reflected signals that are summed and phase averaged with the forward signals at each directional coupler. The phase drifts of the 7/8” cable are compensated for by...

Two LLRF systems were designed and built for the HINS program at Fermilab. The first system is used in Horizontal Test Stand for commissioning and testing of 325 MHz SRF spoke resonators. The second one is for HINS 6-cavity test accelerator with ferrite vector modulators used in a high power distribution scheme from a single klystron. In addition to standard LLRF functions, each of the systems...

The European XFEL will require synchronization of RF, optical and digital subsystems with accuracies reaching levels down to 10 fs. The entire synchronization system will consist of both RF coax cable and optical distrubution links working complementary to assure the required performance and availability. The plans for the RF part of the synchronization system will be covered by this...
