Agenda
- Quartz and PMT purchases for ancillary detectors (Mark Pitt) slides
- Concrete shielding of Upstream Torus region (Ciprian Gal) docDB1292
Minutes
- Quartz and PMT purchases for aux sets:
- MP: request is approval for a large purchase for the auxiliary detectors
- MP: most of the components have been bought for other detectors in the experiment.
- MP: the SAMs will have different tubes; that have worked fine before in similar experimental settings
- CG: we will have spares for the PMTs?
- MP: counts already have spares in them
- CG: DBM quartz position? Should it not be inside the segment?
- MP: the quartz is radially in. It is detecting low flux things but it gets to the phototubes but shielded by the segment Pb lip
- MP: the diffuse background can be picked up the DBM but would be swamped by signal in the quartz of the MD.
- CG: SAM PE yield comparable to what we had in PREX-2/CREX?
- MP: we are seeing a little larger PE yield (7 in PREX-2/CREX), but the light guide is shorter.
- DMeekins: Is there a way to disable the HV on the tubes on a fault?
- CG: we can investigate the inclusion of an interlock for the HV mainframe and will get back to DM with the options available.
- CG: those present unanimously agreed to proceed with the procurement
- Concrete shielding change:
- CG: request is made to simplify the procurement process. HD concrete purchasing is proving to be quite difficult and expensive
- RW: were the side holes included in the US torus wall?
- CG: Zuhal included them in the simulation and the radiation field outside of the wall is not changed significantly so we are good to go with that change as well.
- CG: 24h were allowed for people to bring up concerns. None were registered, and the all the attendees at the meeting agreed that this change makes sense.
