[PEPPo] Weekly Meeting, Wednesday 11/9 @ 10:30EST

[Joseph Grames]

All very reasonable.  Until the apparatus is well understood all tests 
will be pulsed, meaning CW inhibit = ON.  I'll start on estimates of 
beam loss and heating for the more general CW case, following 
calculations Bob Michaels provided for our target, calculations I did 
for Moller foil ~years ago and discussing with Danny/Pavel if thermal 
analysis can be done.
