The next-generation LLRF control system based on MTCA.4 for the J-PARC RCS was successfully deployed in 2019. The performance of the beam loading compensation is much improved and the high intensity beam up to the design intensity, 8.3e13 protons per pulse, is stably accelerated. During the development, we have been supported by the various ingenuity of Japanese companies. The EPICS IOC on...
The high-energy photon source (HEPS) is a 6-GeV ultralow emittance synchrotron radiation light source being built in China. The HEPS global timing system has been designed using MicroTCA.4 based event timing technologies. A prototype bench test system has been developed, and some critical parameters of the timing system have been tested and confirmed using this prototype system. This report...
The Shanghai soft X-ray Free-Electron Laser facility (SXFEL) is
the first X-band FEL facility in China, being developed in two steps,
the SXFEL test facility (SXFEL-TF) and the SXFEL user facility
(SXFEL-UF).The SXFEL-TF, generates 8.8 nm FEL radiation using an 840 MeV
electron Linac passing through the two-stage cascaded HGHG-HGHG or
EEHG-HGHG (echo-enabled harmonic generation, high-gain...
A digital LLRF control has been implemented at the CW linac ELBE at Helmholtz-Zentrum Dresden-Rossendorf. The system is based on the MicroTCA.4 standard and drives four superconducting TESLA cavities and two normal conducting buncher cavities. The system enables a higher flexibility of the field control, improved diagnostics and field stability compared to the analogue system which was used...
