General Meeting Summary 11/29/18

MAGNET (Bogdan, Charles)

• Fully assembled

• coil to ground was tested
• not yet energized
• water cooling still being worked on

• Magnet test plan

• planning to measure longitudinal and transverse points inside bore and gap
• determine details of measurement speeds, etc. when service infrastructure finalized

CRYSTALS (Vladimir, Sasha, ...)

• Have received 20 crystals from CYRTUR - company provided specs

• Inspection and initial measurements look quite good
• Expect total of 100 crystals from this order

• Paperwork for CRYTUR additional 55 crystals through CUA and 150 crystals through JLab is being processed - ~40 more through OU likely. Anticipated delivery schedule is March, June, October 2019.

• Waiting to receive 160 replacement crystals from SICCAS from previous order and signature of next contract over ~400 crystals

PROTOTYPE (Vladimir, Sasha)

• Prototype is installed in Hall D - some optimizations needed along the way, e.g. platform construction, channels, interlocks

• Calibration procedure [HV scan and voltage adjustment] has been developed and is being tested (Vladimir)

• Working on reconstruction software (Sasha)

• First beam on prototype [1]

• Testplan with beam [2]

• Initially plan to take data at different voltage settings scanning beam across calorimeter in steps in x and y

• Also measure properties like energy resolution, light yield as function of temperature, position resolution, etc.

NPS COLLABORATION MEETING - 1 FEBRUARY 2019 (ARC 231/233)

• Discussion of the draft agenda

• Include mechanical design into M. Fowler's talk
• All talks listed under point (2) have to include timelines, tasks to complete and manpower - speakers might view their talks as sort of a dry run for the experiment readiness review
• In general note that charge elements will include:

• past successes of the group
• how long group typically takes to get publications out
• projection of path and timeline from analysis to publication

• Action items:

• Convert agenda draft into a timetable
• Include additional information for talks in (2)
• Contact speakers

HALL C WINTER MEETING

• Discussion of NPS Overview talk invitation - Charles volunteers to give the talk
