Superconducting Radio-Frequency Technology: Understanding and Improvements of Limitations Through Application of Cryogenic Instrumentation
A large number of diagnostic methods have been developed during the last two decades to gain insight in limiting phenomena occurring in superconducting rf cavities during operation. Temperature mapping in subcooled and superfluid helium and x-ray mapping have successfully been applied to understand and subsequently prevent or eliminate loss mechanisms present in these devices. Newer techniques specific to problems such as rf window arcing are under development. This paper reviews various diagnostic techniques and discusses the impact of their application on progress made in SRF technology
