Minutes of feedthrough meeting of 21 May, 2002. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Present: Pof, FH, PB, WW, ML, AD, ASD *) Milestones: - The rebuilt ft39 was cold tested (and passed). - ft41 was opened to replace the faulty vacuum cable(s) from slot six. - ft42 was cold tested - it passed. - ft43 pigtails were installed. *) The next feedthroughs types to be built will be: ft44 HEC ft45 Special ft46 HEC ft47 Special ft48 HEC ft49 Special ft50 HEC We may opt to sneak in the FCAL somewhere between ft44 and ft50 if the T52 FCAL cables arrive in the near future. The three remaining Standard feedthroughs will be built at the end. *) The cold flange with the leaky pincarrier-to-flange weld which was removed from ft39 was repaired with a minor touch-up weld. Dave Smith re-machined the flange so that it can be re-used as a spare, and the flange has been leak checked again to make sure it was not damaged during the machining. *) After the final (ft54) feedthrough is built, we will assemble for long term storage a full set of spares, including flanges with pincarriers already welded, so that we could proceed with the construction of another feedthrough if required. *) Pof, PB, Wendy, and Fiona will proceed with making their CERN travel arrangements this week.
