MAGNET UPDATES
- Yoke delayed until end of September
- Main coil delayed until end of November
- company miscalculated amount of copper needed and takes a few months to obtain
- in general, company does good work
- Test lab configuration for magnet assembly and testing ongoing
- due to delays of magnet component shipping magnet tests will be delayed past December
CRYSTALS AND PMTS
- Received 100 PMTs from Hamamatsu
- diameter < 19.2 mm according to specifications
- Crystal shipment delayed
- Check with company at beginning of September for expected delivery dates
- Crystal Q&A documentation discussion
- need to make sure that there is unique labeling and data sheet for each crystal
- create an NPS database that includes crystal info, but also info on PMTs, frame etc.
- indicate what tests have been done by Giessen and/or CMS - use this information to determine if crystal good with respect to these two
- Discussion about resource optimization
- split measurements between institutions
- measure only subsets
- external resources to supplement resources at CUA/IPNO - Glasgow may be able to help with some tests
- Discussion about crystal measurement procedures
- make a detailed list of procedures to follow to minimize damage to crystals
FRAME UPDATES
- Designer will be available full time at IPNO in September
- Currently working on curing system optimization and finalization
- Still need some final design optimizations from JLab designer, e.g. interference in detector box
DISCUSSION ABOUT 2017 ACTION ITEM LIST
- Magnet mapping - discussions and write-up of plan ongoing
- plan to map along beam line for 2-3 positions
- primary tools: hall probe and oscilloscope
- may be able to do some tests with yoke and corrector coil before main coil arrives
- Platform - JLab designer
- Readout
- Discussion about data rate
- DVCS experience showed 20 MB/sec was fine, but 40 MB challenging
- Crystals - large part of planning work completed, some still ongoing, waiting for crystals
- PMT and HV bases - concept finalized, procurement ongoing
DAQ AND READOUT
