Description

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 harmonic
generation) scheme, started construction at the end of 2014, began
commissioning by the end of 2016, and passed national acceptance testing
in November 2020. Now, the SXFEL-UF is under construction, with an
upgrading the linac energy to 1.5GeV, and the building of a second
undulator line and five experimental end-stations.
MicroTCA-based Low Level RF (LLRF) system plays an important
role in electromagnetic field control, signal monitoring and machine
protection. There are 12 RF stations in SXFEL-TF with different
frequencies (S-band, C-band and X-band). This talk gives an introduction
of the development of the software and the firmware, operation status
and performance of the LLRF system.
