Present: M.D., A.D., J.S., S.Š
General:
- Quorum: do we need to write a GDH-specific appeal letter?
- Elton's comments (only one from the collaboration so far).
- Goal: submit the proposal sometimes Friday 19th (best) or this week end (acceptable), or Monday before 8am (deadline). What's left to be done for the proposal to be ready?
- M.D:
- Provided estimate for the trigger rates and trigger+tagger rates from BH and Compton. Large rates are found, limiting our DAQ rate and reducing our stats by a factor of 0.36.
- Implemented some of Elton's comments.
- S.Š:
- J. S.:
- A. D.:
- Wrote to the collaboration re. new version of the proposal. (No reply at all.)
- Added a small discussion on polarized background (Polarized Compton background is nearly fully suppressed because of the GDH SR on electron and because it's integrant is significant only near the electron mass << our nu)
- Implemented Mark's results on BH and Compton background in the proposal. In particular, we now have a decent section on unpolarized backgrounds rather than a space-holder.
- Updated the figures, photon flux used, accidental background, precision reached, run-time discussions to account of the ~2/3 drop in statistics.
- We now propose to run 10 days at 4 GeV instead of 5 days (12 GeV run remains at 17 days).
- Implemented some of Elton comments left after Mark's pass at them.
- Starting to look at additional forms for the proposal:
- Physics Category: hadron spectra as probe of QCD, or long structure of hadrons
- Major installation:
- Hall D FROST target.
- How about Moller?
- Does electron helicity monitoring count as major equipment?
- Not too costly, a few $10k, but will need accelerator and possibly electronic group support. => Mention it in the form.
- Should we mention the beam hardener? What else?
- hazard:
- electrical equipment, beamline magnet…all usual stuff… do we need to mention them?
- target magnet
- Computing req. list.
- Add Silo/Mass Storage (Tape)
- Add Amount of Simulated Data Expected
- Add Amount of Raw Data Expected(TB)
- Add Amount of Processed Data Expected(TB)
- Add Online Storage Disk Required (TB)
- Add Imported Data Expected from Offsite Institution
- Add Exported Data Expected to Offsite Locations
- Computing
- Add Simulation Requirements(SPEC CINT 2000hrs)
- Add Production(Replay, Analysis, Cooking) Requirements (SPEC CINT 2000hrs)
- Other special request to IT?
