Description
RF testing and performance analysis of low beta superconducting cavity cryomodules are in progress for the two facilities: High Intensity Heavy Ion Accelerator (HIAF) and Chinese initiative Accelerator Driven System (CiADS). This poster describes the status and progress of RF conditioning, plasma cleaning, key cavity parameter identification, cavity operation limits testing, and stability testing of cavities and cryomodules during horizontal and integration testing. Advanced measurement techniques are introduced, such as online measurement of key cavity parameters (loaded Q and cavity frequency) during cryomodule cooling-down process, as well as dynamic detuning and dynamic loaded Q identificatoin in SEL and GDR loops. In addition, cavity quench strong textbehaviors under pulsed and CW RF operations are also discussed.
