Description
SRF cavity development, as well as cryomodule design, plays a key role in the development of future accelerators, as demonstrated by CERN projects such as HL-LHC CRAB cavities in bulk niobium (and related cryomodule) and High Gradient cavities in bulk niobium (and related cryomodule). At CERN, the respect of Essential Safety requirements is demanded for all pressurized equipment, category where the superconducting RF cavities and cryomodules can be legitimately located. Due to the operating condition and design aspects (i.e. use of niobium for a pressure vessel, limitation in plastic deformation), the respect of those requirements is not always straightforward, presenting not-conformity with standards that need to be deal with. In addition, for projects developed by institute collaboration, European standards and ASME standard are often mixed and cohabiting, raising questions related to compatibility and interchangeability.
The CRAB cavity project is presented as a real case study of this problematic development, giving an overview on the steps performed up to now and presenting the future planned actions to provide CERN with an equipment suitable for a safe use.
