esr 1 mil thick purchase order sent expect to receive in january no adhesive layer will be attached
received 6 scintillator bars 2 regular 2 narrow and 2 short
some bars are out of tolerance by 1 or two mils above 5 mil tolerance
working on 3rd batch produced 76 normal bars 1/8" inch short , 12 of them not accepted yet
sasha setting up for scintillator measurements put into dark box spring loaded mechanism to hold pmts Sr source at various points, get adc and tdc light output spectrum a mystery
all parts made for mini-tof mid january start gluing, finish tresting this week start early january gluing ESR
chuck is putiing mini tof ideas into final design
Chuck thinks eyes-on would be a good idea.
