1.) Simulation: Checked in latest Qweak.euclid file into CVS.
3.) Readout:
Order trigger electronics for GEM (R. Bellazzini, NIM A478, 2002 pg
13-15), A203
pre-amp and pulse shaper which is fed into AMPTEK's
A206 voltage
amplifier and low level discriminator.
Now have a 16 channel TTL-LVDS converter
in hand ($200)
which appears to work. We need build proper cables/adapters
to connect it to the Helix board.
5.) Test Apparatus
Buildings and Grounds finally reduced my power line noise from
1/2 volt to less than 2mV so now I can document the GEM signal.
GEM signal from Cosmics
Added scintillator paddle below
GEM detector.
looked at coincidence between
scintillator and GEM
