Agenda
Note: agenda is still being edited
- General goals for this "supergroup" (Mark/KK)
- Beam monitoring (Mark)
- Background material Beam monitoring info
- Beam size monitor with cavities (Mike Woods, SLAC, KK mentioned this)
- Beam monitor parasitic development work (KK potentially has graduate student available for this)
- Synchrotron radiation - any issues here?
- R&D plan needs to focus primarily on charge monitoring - how to proceed? (ie. parasitic work in Hall A or C or both? Qweak may be resistant to changes since things are working at an acceptable level now, but that is not confirmed.)
- Tracking (Mark, David A.)
- Background: Director's Review Tracking Talk (see slides 4,8,9,10,12) Tracking background info
- Background: Initial CAD layout from Dec. 2010 KK talk Tracking CAD info
- Background: Small acceptance pion counting detector from Souder Dec. 2010 talk Souder pion detector info
- Are we happy with decision to just measure scattered theta and not E'?
- Can initial work proceed without further simulations (other than default profiles of the scattered flux at the three z locations in the most current spectrometer design)?
- What work needs to be done by summer? (suggestions:)
- further "Roman pot" research
- finalize decision for "Region 3" technology - straws or GEMs?
- Learn more about running GEMs in vacuum (assuming that is default choice for Region 1 and 2)
- Number/sizes of detectors in each region
- Is this the correct subgroup for Souder's counting mode pion detector?
- Integrating detectors (Mark, Michael, Dave M.)
- Background: Director's Review Integrating Detectors Talk (see slides 2,3,18,19,27,31) Integrating Detectors info
- Background: Initial CAD layout from Dec. 2010 KK talk Detectors CAD info
- Can initial work proceed without further simulations (other than default profiles of the scattered flux at the focal plane in the most current spectrometer design)?
- Stand-alone GEANT4 light transport simulations for some default radiator/air lightguide combinations will probably be useful.
- PMT diameter, Winston cones? (KK can comment)
- Pion detector ideas (KK)
- Ideas for coupling others into UMass Solidworks CAD design for detector/supports
- Next meeting time/goals
- Mark Pitt will establish three separate JLAB mailing lists (for beam monitoring, tracking detectors, integrating detectors), since some sub-group discussions may become too detailed for general consumption. This is also a way to self-organize and find out who might be available to contribute.
- For next meeting, a good goal would be for each subgroup leader to establish communications with his sub-group via email, prepare a list of goals for mid-summer, determine what tools (CAD, simulation, etc.) are needed to proceed, and have an initial list of volunteers to work on the topics.
- Perhaps we need 3 weeks till we can do this next supergroup meeting?
- After that, how does meeting every 3 weeks for the supergroup sound? Subgroups can meet as they see fit in between time (email exchanges, teleconferences, etc.)
