start counter meeting minutes
• notes as minutes • present • sections
To Do
- only one alarm clock, not three, check it in
Notes
did a single photon measuemrnt of phototube, number os photoelectrons
sraifht elgen board , put that at different position can measure the gain of the sipm
hv problemsd, fixed yesterday
looking at mcneal bar
one broken edges look good a month has passed, noticing internal crazing as seen in previous bars took up to lab, looked at it with laser, see defects, see same haze o fine tracks, internal crazing 2mm ej212 bar originally sent same sort of deterization 3 mm bar srai=ght, also 204 bar, they look fine, kept at FIU, handled only by werner and Eric
internal crazing
mainframe hv died, can only turn on 2 or three channels 1454 want to borrow something CAEN unit belongs to pyrex need 6 channels model number for caen mainframe look at hall b mainframe caen sy2527
dollar amount of contract, does that sijmplify
frame proposal writing process for werner measure scintillators get them started on next batch no money, get started on next batch
is there a way we can fund them
