I went through the parts and pieces at the test stand to determine how many drawers could be put together as spares. I tried to invision all the steps I went through during October to fully test a drawer including all the things that needed to be fixed or replaced. Inventory --------- 6 box bottoms -> some of these made need the holes sealed and retapped in order to mount the motherboards properly 8 box lids -> they all look ok 5 front bulkheads - 2 good signal connectors + 1 with cracked piece that may be usable - 9 pulser connectors - all LV connectors plus a couple of spares - 6 HV fanout wires + connectors (one end is soldered to trio of SHV connectors on front, and the other end has a connector for connecting to motherboard - each drawer needs two) - 30 SHV connectors plus 5-6 spares 6 rear bulkheads - 20 cups - plenty of rings and cylindrical rods (needed for sockets) - 20-25 1 inch screws (0/80?) - 20-25 springs - 11 orange rubber rings - 31 complete socket + wire assemblies - 10-15 possibly reusable wire assemblies IF we get new sockets with collars (requires desoldering and resoldering all those wires) Preamps -> Plenty (at least 200, probably closer to 400) Bases -> I found 33. They should all be good, but we may have inadvertently damaged a few during Oct/Nov. Right hand connectors for preamps -> I found 13 (need three per motherboard). Conclusion ---------- If only we had one more front bulkhead, we could strive for six spare drawers. In terms of parts, I think we should try to have enough parts for at least six drawers, even if we can only complete five. I also would like to go on the assumption that I can not use anything already installed. To do that, we need that is not already here at D0: 6 fully stuffed motherboards [should be done] 1 front bulkhead 4 signal connectors with ribbon cable 3 pulser connectors for front bulkhead 6 HV fanout wire assemblies (from bulkhead to motherboard) 10 cups [at UTA?] 30 1-in 0/80 flat-head screws [should be stock item] 30 springs (I don't have specs) 2 dozen rubber rings [Home Depot or such] 2 dozen sockets with collars [Dean will order with PMTs] 5 right hand connectors for preamps
