[Tpe] Fwd: TPE Shutdown

[Larry Weinstein]

Dear TPEers,

Thanks to Doug and Rob for dismounting the calorimeter tomorrow.

In addition to running TPECal cosmics during the break, it would be 
great if we could take advantage of the farms remaining up and replay 
lots of runs.  We should replay the runs starting from the ones taken on 
the 10th, making sure that they each have the correct Torus field.

That way we might even be able to have preliminary triple ratios early 
in the new year (in addition to making sure that all the low level stuff 
is correct).  We will also want to check the back angle TOF thresholds 
to see if we want to lower the thresholds like Frost did.

- Larry

TPE group,
      Since we will not be getting beam before the shutdown, we powering down
      -- Tagger magnet
      -- Main torus
      -- Minitorus
      -- Pair spec.
      -- Fresc. magnet
      -- EC HV
      -- DC HV LV (George)
      -- EC HV
      -- SC HV
      -- TPE Cal
      -- SFM/DFM
      -- Warmed Target (w/ D. Kashy)

      We will take TPE Calorimeter cosmic runs during the shutdown.  Doug
and I will be taking the TPECal down tomorrow morning at 7:00.
Sergey informs me that we will able to take data after the power
shutdown on the 28th.   We are penciled in to have the calorimeter
resurveyed on the 5th of January.

Regards,
Robert
