Present: Chris Allgower, Andy Bacher, Paul Pancella, Tom Rinckel, Sitaram Shastry
Meeting came to order at 3:05 pm.
SEPTUM MAGNET
Tom Rinckel gave an update on the progress of septum magnet coil winding. One coil has been wound and baked, and 2 layers of the second have been wound. First coil still needs water fittings soldered on, still a few days of work to complete.
Vacuum chamber for the septum magnet is completely designed and drawn. Major machining has just gone out for bids. Some machining and all welding will be done in house.
FERA SUPPLY PROBLEM
Tom reported no word back from LeCroy salesman about the FERA supply problem. Our stated strategy is to try very hard to procure sufficient FERA modules before forking on a substitute. Word is that Ed has begun the process of borrowing some stuff from Brookhaven. Chris will ask Hal Spinka if we can borrow some, and Paul will contact Jack Rappaport. STAR may be another source, depending on schedules.
BUDGET AND MANPOWER
Discussion moved to the budget request from IUCF Experimental support. Tom started with last year's request and modified for our expected needs, then Ed and Andy gave some input. (Incidentally, that request included about $54k for purchasing 18 new FERA modules.) Andy suggested that magnetic shielding for individual lead glass phototubes be added as a line separate from field clamps on the beam pipe and u.s. face of the 6-degree magnet. Some other minor changes were discussed, but the result is that a good document is ready to submit to Jacobs.
MISCELLANEOUS HARDWARE, WIRE CHAMBERS
We still need to look at thin vacuum windows in the channel in some detail. In particular, the final exit window before the end detectors is now larger than previously imagined. Can it be thin enough?
Keith Solberg has finished detailing circuit boards for the new wire chambers, and sent them out for fabrication. They were designed to require minimal additional machining in house, and will thus be virtually ready to wind wire on when returned.
Front plates have been punched for patch panels, we are still waiting for the bulkhead connectors to install. Parts for delay boxes are starting to come in. Shastry and Allgower will be assembling these.
LEAD GLASS
Chris reported on the status of lead glass detector testing. All but one of the IUCF detectors have passed, meaning 159 of these units are available. Only 3 of 9 "repaired" ANL modules passed the latest test, and nothing has been done yet about the "low-gain" bases. This means about 80 ANL detectors are ready. This total is therefore still short of the 256 we plan to use. Chris has not yet located the large chunks of lead glass which Pickar incorporates in his planned array (5-10 units, including a separate array for detecting photons at 0 scattering angle). Andy says he knows where these are.
Meeting adjourned at about 4:15
