[Brahms-l] Fw: SPY news update: schedule ... tight schedule ... Time Meeting on Feb. 17, 2004

fYI

In addition i will like to mentioned if not seen in the e-logs that we have
had another crash with pii3 late this afternoon that caused havoc with data
taking. The cause for this failure is unknown, but we will like at a
convinient time, most likely during the Wenesday 8 hour access to swith pii3
to another physical unit. This assumes it stay up until then.
It was proven that data collection can continue using opus only, while
controlling HV and monitoring the data
proved to be an issue. One way around this is to ensure we have a working
version of root+brat=brahvo on opus.I hope this can be looked into.

regards
 Flemming

PS. Some scheuling comments:
a) In case of pii3/daq issues please contact hiro
b) During this weekend I will coordinate run-plans, while JH will take care
of this from Monday through Thursay, where I will be away from the lab.
c) Dana is also back from Tuesday and on.
e) recall that Monday is presidents day (a lab holiday)
f) The run plan for the long weekend call for running at 4 deg, mainly lots
of high field running to get significant statistics for physics (suppresion)
at large rapidity.
