Present: Chris Allgower, Andy Bacher, Hermann Nann, Paul Pancella, Tom Rinckel, Sitaram Shastry, Ed Stephenson
Meeting came to order at 3:05 pm.
SEPTUM MAGNET
Tom reported that the coil is ready to have water fittings soldered to the ends, and that the need for jumpers between coils has been eliminated. Both coils should be completely done in about another week. He expects the vacuum chamber to be welded and leak checked about a week after that. The magnet mapper is aligned, and power supplies should soon be ready. Mike Stines needs a day or two with the substation disconnected (no power to CIS, RFQ, DTL, CIPIOS) to make the final hookup, then we would be ready to map. This could possibly happen during the Cooler access just before the Thanksgiving holiday. We need to coordinate this with the rest of the lab through Gary East. It seems doubtful now that the mapping of this magnet will be finished before Christmas. We are roughly one month behind the schedule that was developed over the summer.
LED PULSER
Tom also reported that Doug Bilodeau is developing an LED pulser system for STAR, which could certainly meet our less stringent requirements. We would need it primarily for timing, so the output of a single light source should be distributed by fiber optics to all of our channel scintillators and a few of the lead glass detectors. It was agreed that we should simply monitor this development and request a duplicate LED source be made when the time comes.
BUDGET
Tom has discussed the budget requests with Jacobs, who is scheduled to present a budget at this afternoon's faculty meeting. Requests were greater than funds available, and some whittling is being done. Aside from a cryo pump system, it sounds like we will get most of what we asked for.
ELECTRONICS
Connectors for 4 more delay boxes have arrived, and construction is in progress. The order for patch panel connectors finally went out, and it is hoped that these will arrive soon (in stock item). Chris has put the electronics diagram into xfig format, from which postscript files can be made and printed. Besides the continuing quest for FERA modules, we need to locate a programmable delay box (from Brookhaven?) pretty soon, as we would like to use it in the channel tests early next year. Based on a reply from Jack Rapaport, we should add Steve Wender at LANL to our list of people to beg for FERAs.
LEAD GLASS
All 160 of the IUCF modules have been checked out and passed. The 8 large chunks are also deemed useable by Allgower. 78 of the ANL detectors have passed. Of the other 21 ANL counters, Chris is ready to retest 9 that he has worked on. There was some discussion about when to stop this process. The consensus was that we should still be shooting for 256 useable counters, of which perhaps only 4 would be the large ones. Since we would also desire spares, the repair and testing process should continue for now. Pancella will present a proposed stack configuration at the next meeting for discussion.
MISCELLANEOUS
Someone (Ed? Paul?) needs to make some drawings for the first generation of channel scintillators so John Vanderwerp can build them when the material comes. Ed will be gone next week.
The annual list of computer accounts to terminate contains those used by our various Russian visitors over the last year. The group suggested we ask Yoder not to delete Adam Smith's account. Someone needs to determine if there is anything worth saving on the others, or simply back them up and let them be deleted. Chris will check into Pavel's account.
It is probably time to revisit the jobs list that Ed made in late September. This will be on the agenda either next week or the one following. We should also look ahead to personnel and lab schedules through January or February. Accelerator shutdown is now scheduled for 12/18/00; the 2001 startup date has not yet been determined. We must also start to plan for three different visiting committees to be here over the next few months: the Physics Department Review November 27-28, the NSF site visit December 18-19, and the IU research committee January 11-13.
The meeting adjourned at about 4:05 pm.
