In 2014, the R&D of RF group was mainly concentrated on operation and maintenance of RF equipments inHIRFL, in addition, we also devoted to the upgrading of existing RF system and R&D of equipments in new projects.After all the efforts, many important results have been obtained.In the operation and maintenance, the fault time in beam commissioning and operation decreased by 75% and50% respectively compared to last year, at the same time, greatly shortened the time of RF parameters measurementand equipment booting. All the above works effectively ensured the smooth going of physics experiment.
