Description
The digital low level RF systems that are used to operate 17 of the 53 cryomodules that are installed in CEBAF have the capability to log 17 waveforms either on demand or when one of the cavities in the cryomodules trips off. In 2018, the software and hardware in the digital low-level RF systems was configured such that a fault would trigger an acquisition process to record 17 RF waveform signals for each of the 8 cavities within the cryomodule for subsequent analysis. To date approximately 15,000 faults have been analyzed. This contribution will describe the types of faults encountered during operation and their signatures in the time domain data, as well as how it is being used to modify the setup of the machine and implement improvements to the cryomodules.
