Minutes of feedthrough meeting of 18 June, 2001. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Present: PB, Pof, GV, AD, ASD, FH, MGF *) Milestones - The three feedthroughs (ft06, ft07, and ft08) built with the 24 pincarriers that arrived on 15 May were completed on 14 June, taking a total of 23 days for completion (start date was 23 May). - Four vacuum cables arrived from FCI; still 232 to come... - Six more shipping crates have been built by Dave Smith. *) Chris Oram has provided a list of suggestions following his site visit on 29 May. These are all in the process of being implemented into our QA/QC procedures. *) We will perform some drop tests with ft-1 in its shipping crate this week to determine whether or not the bellows are at risk of being damaged by the bellows braces in case of rough treatment during shipping. *) A quote was received this week from Axon for additional pigtail jumpers and DC test harnesses. We had requested a quote for two DC test harnesses, eight 50 Ohm pigtail jumpers, and two 25 Ohm pigtail jumpers. Axon replied with a quote reflecting their minimum order: 5 DC test harnesses US$921 each 5 50 Ohm pigtail jumpers US$565 each or 10 50 Ohm pigtail jumpers US$532 each 5 25 Ohm pigtail jumpers US$566 each No delivery time was specified in Axon's reply. We will proceed with an order for ten 50 Ohm pigtail jumpers (no DC test harnesses) which will give us two complete sets of impedance matched (for Standard feedthroughs) jumpers plus four spare 50 Ohm pigtail jumpers. The two DC test harnesses were intended as spares; in a pinch, we could manufacture these ourselves by cannibalizing the prototype LV vacuum cables. Delivery time will be specified as no greater than three months. Agenda for next week: ^^^^^^^^^^^^^^^^^^^^^ - Milestones - Drop test report - Plans for the week - Plans for LARG week - AOB
