Incoming inspection of the cavities at saclay Christelle Cloué 2017-11-07/08 : 7th SRF Collaboration Meeting @ CEA

Documents delivered with the cavity Outgoing inspection report – inspection of the cavity after test operations, before shipment to Saclay (see LASA Outgoing inspection report) Mechanical report for cavity alignment (discussions in progress with LASA) template_Mbeta_dim_data_export_v3.xlsx RF reports (reference measurements under vacuum and at atmospheric pressure) – format file to be defined (XFEL templates to be adapted .txt, .xlsx) Vacuum and RGA reports according to the requirements of the Interface Document NCR related to interfaces for string assembly or to possible consequence on the cavity performances 2017-11-07/08 : 7th SRF Collaboration Meeting @ CEA

Operations after the cavity delivery Operations carried out on the cavity at the delivery in Saclay Outside the clean room Incoming inspection RF measurements, cavity under vacuum Inside the clean room Leak check RF measurements, cavity at atmospheric pressure without clamps (TBC) 2017-11-07/08 : 7th SRF Collaboration Meeting @ CEA

Incoming inspection Documentation check External inspection of the box Inspection of the outside of the box and the fasteners / lock clips for obvious mechanical damages, e.g. cracks, dents or scratches Internal inspection of the box Shock loggers status and readout Check if there are any obvious damages or irregularities Cavity visual inspection Inspection of the outside of the cavity for physical damage, presence of external contamination Check the cavity from mechanical point of view, if there are any irregularities according to the specifications (interface drawings) Example : the length of the rods on the cavity flanges, the presence of a blind flange on the angle valve 2017-11-07/08 : 7th SRF Collaboration Meeting @ CEA

RF measurements outside the clean room RF measurements, cavity under vacuum Measurement of the cavity fundamental mode spectra, and transmission mode and Q of the fundamental mode Comparison with the measurements performed before delivery Need of a database for the files download and upload RF test bench at CEA 2017-11-07/08 : 7th SRF Collaboration Meeting @ CEA

Tests inside the clean ROOM Leak check (vacuum pressure, background, leak rate) RF measurement, cavity at atmospheric pressure without clamps (TBC) Measurement of the cavity fundamental mode spectra, and transmission mode and Q of the fundamental mode 2017-11-07/08 : 7th SRF Collaboration Meeting @ CEA
