1.) Simulation: Neven preping Qweak talk and can't work on pulling ionization routines out of Garfield. I retrieve the "CAR" archive from CERN which contains all the Garfield source code. I was able to extract all the fortran routines but I couldn't get it to compile using the patchy tool set (documentation is difficult and memory is also bad on how to compile from "CAR" files).
2.) GEM Power supply: Current Monitor having problem with new currant amplification chips. The amps burn out after 2800 Volts whereas before they were good up to 4000 Volts. Investigation underway. Good news is that for the trigger circuit the monitor only needs to work at about 2000 Volts.
3.) Readout: Someone damaged the wedge based wire binding
tool. Can't thread in the wire. New tool on order.
Using ball bonder to connect TTL->LVDS chip to PC board for
testing with new pulser.
4.) Detector Design:
Contract for detector rotator design is written and in hands of
engineer for review.
Changed euclid file code for primary collimator in order
to make it easier to insert code for GEM detector design. The
primary collimator was designed to be in two pieced with
a gap in between which could house the GEM detector. The
new code should not alter the
collimator design.

5.) Test Apparatus : Ordered more gasket material.
