Mechanical design
We had another design meeting last Thursday, September ??? where Chuck showed [??? slides] of his work thus far in modifying the design to fit in the FCAL/TOF support structure. We reviewed some of those ideas. They appear to give us the needed clearance.
Chuck has been working on the mechanical support for the TOF. He showed [??? some slides] sketching ideas thus far, especially for holding the vertically-oriented plane.
new progress
CAEN TDC stops triggering
sergey b has not seen it
one of the six pmt, signal 15 % strange pulse shape, very broad
110 ps mean time per plane
ian and chuck will talk this afternoon
paper on xp2020
need photoelectons per mev can be measured with mips if tube gain is known
