Hi All,

  Here are the questions I wrote down from the Run Control meeting last week.
I don’t know that I captured everything. Some of these were answered at the
CPP meeting yesterday.


- Rate estimates: What current to run at for the calibration runs Sean D. will run
 at the beginning of the Run Period (150nA?)

- Should we align multiple diamonds? Hovanes had a couple of considerations
but it seemed Elton should be involved in that decision.

- How much amorphous running do we need relative to diamond?

- Should we use the 75um or 750um PS converter?

- Straight tracks:
  - Do we need straight track runs?
  - Requires ramping solenoid up/down
  - Could do in conjunction with first TAC run near the first beam studies day
    so as not to lose any time with solenoid ramping

- Who will serve as Analysis Coordinator?




Regards,
-David
