CERN Feedthrough Reception Status Report ---------------------------------------- John Lindner January 9, 2002 STATUS Feedthroughs received at CERN: FT00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21 The pigtails are bagged for: FT06, 09, 11, 12, 13, 14, 15, 17 (half-bagged), 19, 21 All FT's at CERN have been leak checked and electrically tested. All passed except for the following: FT 10, 12, 15, 19 have damaged pigtails. FT 13 has a small leak (10^-8) in the seal ring-warm flange weld. ADDITIONAL ISSUES 1) When the FT crates were opened, there was often dirt on the FT. Mostly it was black soot in the folds of the bellows or a white deposit near the cuff ring. I do not believe this is problematice, especially considering the cleanliness of the rest of bldg 180. 2) When a FT crate was first opened, we would make a series of checks. These checks were identical with each FT but there is nowhere on the FT CERN Reception Form to note these checks. I suggest including some check boxes with the following: -No visible damage to FT -Foam in bellows bracing -Two screws in each pincarrier cover -Positive pressure in bag -Dessicant present -No damage to mounting brackets (ie. no buckling)
