Last meeting: Wednesday, March 1, 2017 2:00pm EST
Agenda
- Updates
- Next meeting time
Minutes
Attending: Jim, Ernie, Cameron, Juliette, KK
- Juliette still needs to take spectrometer summary and turn it into a schedule/task list
- Prototype status
- envelope fitting
- redid calculations
- rewrote the specs
- Question - how many vendors?
- Stonybrook now, so should be ok
- NH + Everson; if too different, then pursue third
- considering not using the fast-setting, high rad-hardness epoxy
- don't need rad-hardness - could test another one
- sets faster - need to test?
- should be getting quotes soon
- special meeting, then order within a day or two after
- Cameron update
- good progress on radiation simulation to design localized shielding
- want to keep track of significant sources of radiation
- neutron radiation increased after changing thickness of roof
- continue pre-engineering
- how to support the inner photon collimator and designing the mount
- Jim or Jason - estimate of the time
- motion system - proof-of-principle for physics and heat dissipation
- need an alignment system, and it will be buried in shielding
- do need to be able to align after pull vacuum (unless rigid enough)
- define beam center-line ahead of time
- vertical and horizontal motion shouldn't be too hard (but not angle adjustments)
- Various other things
- detectors
- shielding
- two JLAB designers from target (Silviu) - time in May and June
- upstream vacuum chamber
- detector support structure
- collimator motion system
- need a plan
- prepare MIT work package for May-September - new contract
- Collaboration meeting late April (probably 21-22, possibly 28-29)
- Next meeting will be March 29, then again April 12, 26th etc.
