DeltaDoverD Progress

1.) SIDIS Analysis

2.) Detector Construction

   4 chambers are built.   

TGEM:

Foils have been mounted on the TGEM comparison chamber.  Both charge collectors are mounted on the TGEM test detectors.  One TGEM test detector has the Thick PC board GEM foils which need much higher HV than the regular GEM foils.  The second TGEM test chamber has 3 GEM foils from CERN.

Need a min of 32 1 Meg Ohm resistors to complete the output termination connenctors. Need 32 more termination connectors made from 16 wires.

Need to grind down 16, M3 bolts for mounting the GEM foils and TGEM PCboards.

Need 24 washers for GEM foils. Check mounting of the TGEM boards. Look up spacing and HV for the TGEM boards.

Need to etch 2 cathods for the TGEm boards.

Qweak:

  1.) Need to do final outer footprint machinging so there is no interference with the Electron profile of the other octant.

  2.)  Need to maching back of the chamber for the Charge collector

 3.) Need to machine thick frames for the cathode and maybe GEM foils.

 4.) Apply electrical insulation to HV distribution boards

5.) Need to mount GEM foils on the Qweak chambers.

3.) SIS3610 I/O software
