2. 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

3. 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)
/08 : 7th SRF Collaboration CEA

4. 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

5. 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
/08 : 7th SRF Collaboration CEA

6. 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
