when arrived on shift. Richard and Aki are playing with target flows and studing the response of ligit, lifetime and BQM rates. continued till 5:00am.

/BOOTed HV crates, restarted CODA and compton since everything hung up.

data taking with unpol D2 at 0.1sccm. WCL23 WCL24 turned off. no holding field.
WCL6 restored to 3800 by the reboot of crate.

restored the emacs crunching window to an organized manner.

real smooth. except that the library linked to onlineGui (version 2.20) seg-faults frequently. version 2.96 seems to have the bugs fixed as it crunched through millions of events OK.

Ben showed up at 8:00 event though the Blast_Shifts sheet has an blank field for 8-16, Sept 14th.

at 8:30, Ben spotted that compton laser rate is essentially 0. suspect laser is not aligned properly. could not reach Bill

10:20am, Doug called. Start attemp to run at half field.
10:40am, Blast PS lowered to 3363.5 Am, has been tuning since
11:50am, CCR stopped tuning.
as of 12:05am, run 2557 going on, no trip yet.

P.S.
lrn to read field magnitude from Epics automatically. to veiw tracks in nsed, use flowing options in Chris':
nsed #### -bm 0.5 or nsed #### MagField.Magnitude=0.5
not sure about onlineGui.
