General Meeting Summary 12/22/16

MAGNET UPDATE

• Main coil procurement - in progress at CUA

• Yoke/steel - searching for suitable vendor to cut the 22 tons of steel already available

• initial quotes from local companies are very high - mainly due to labor hours
• alternatives being explored include cutting of smaller pieces at ODU and expanding the search to non-local vendors. For the latter, transportation/loading may not be cost effective.
• Bogdan is trying to get further feedback from groups that recently ordered magnets including more complicated ones than the NPS one

• Corrector coil - initial quotes are in and seem reasonable

• Discussion about path forward assuming that costs for steel cutting are as quoted

PMT HIGH VOLTAGE BASES

• Work has started at OU including:

• procurement of spare PMTs
• Identification of vendors for boards
• Connectors on signal and HV choices - depends on final design of calorimeter temperature-controlled frame and location of HV and signal patch panels. One option is individual cables, another multimode cables from outside calorimeter to power supplies etc.

PBWO4 CRYSTALS

• Light yield systematic tests ongoing

• Chemical analysis - methods, sampling techniques being developed in collaboration with the VSL at CUA

• Setting up infrastructure in collaboration with VSL to grow crystals at CUA

NPS COLLABORATION MEETING:

• Discussion of agenda

• in preparation for the meeting, think about polarized target and how a bigger figure of merit benefits experiments deuteron photodisintegration

HIGH INTENSITY PHOTON SOURCES

• Discussion of agenda
