Minutes of feedthrough meeting of 4 April, 2000. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Present: MGF, GV, AD, Pof, MLenc, RL, JL, TH, RKK *) Milestones: - 75 pigtails arrived, 51 T47 and 44 T48. All have been processed and all are ok. We are still missing some slots, eg, 15 A/B. MGF will contact Orsay on the missing slots. - The steel for 32 seal rings arrived on 30 March. It was inspected and sent to Sicom the same day. It can be noted (celebrated!) that there is no remaining steel to be delivered to UVIC! - HCC (pincarrier body machining) now has 261 of 396 required 7-row material, and 417 of 396 required 8-row material. - 61 bolt rings were received. One was failed by Sicom, but would be passed by us. None however had been alodined, and so will be returned to Sicom for the alodine treatment. - The two flat weld samples with the correct bevel at the butting edge were received from SM and subsequently sent to CERN. Desirelli has been notified. - A purchase Requisition has been sent to Purchasing Services for the construction of the funnels by SM. - The remaining 21 pieces of cold flange steel were delivered to Ebco last week. - 51 warm flanges arrived from Ebco on 4 April. The remaining 9 will follow, along with the unused blanks. Apparently Ebco couldn't fit all 60 flanges into the crate they intended for the shipment. - Mark did a first-off inspection of the cold flanges at Ebco. Two pincarrier slots were found to be slightly out of tolerance (too tight) in one axis, but otherwise the cold flanges were ok. Ebco will correct the out-of-tolerance problem. *) We are still waiting for delivery of the funnel bases from Sicom. *) We are still waiting for the written report from Bacon Donaldson on the flawed steel. When received, this will be passed on to Pierre Pailler. *) Aboud will now be offered two PCT 8-row pincarriers at $1113.72 each, and two preproduction GSP 7-row pincarriers at $982.85 each, plus $100 for shipping. These prices reflect the replacement cost for production pincarriers. This leaves four GSP pincarriers (two of each type) for the electrical test setups, the minimum required. *) As a side note, ALL preproduction pincarriers (both PCT and GSP) are accounted for, and will be entered into the database for future reckoning. *) Greg is working on an alignment jig to hold the glands at the correct orientations while welding. *) Greg is also working on the test jig for the heater- resistor tests. The test jig will be water cooled, with two thermostats to cut the power if overheated. *) Roy is expecting delivery this week of three types of thermal contact samples (candidate thermal grease alternatives). These are loaded Silicon film or foam. *) All electrical test equipment (hardware) is now functional. Software development (online VI's and offline fortran analysis code) is near completion. *) The ferrite scope should be purchased soon. *) Paul B. is in San Jose this week for service training on the He Leak Detector. *) Margret will attend the April LARG week. She should be supplied with all relevant slides and other material. *) Correction to the minutes of last week: 32 cuff rings and seal rings were sent to BOA, not 34 as reported in the minutes from 27 March. *) Jobs for this week: - Repackage and ship the bolt rings back to Sicom - Set up some DB queries to extract data from the database in a useful form. - Fine tune the electrical test software. - Process the material received. Agenda for next week: ^^^^^^^^^^^^^^^^^^^^^ - Milestones - Status of funnel bases (have they been received?) - Critical path items for construction startup, ie, what are we still missing and when will we get it? - Status of electrical test equipment / software - AOB
