Progress Report of Region3


1) VDC drawings

- upgraded to SolidWorks 2005
     - allows me to draw flexible Kapton boards for wire readout (board can be bens within SW)

- SolidWorks model of the lasertable and wire scanner (elog) .

 -Joe Katich is still working on the microscope lense system. He ordered/got severval lenses, holders and a mounting tube.
   We are aiming for a minimum wire-lense distance of ~10mm and a magnification factor of ~100.

2) Garfield Simulation

- found some bugs in the VDC setup (small position offset of the wire array)
- written a C++ class for reading in the raw Garfield XT output file (elog).
   This will superseds Carissa's Maple script for converting  it into ROOT readable format

3) Geant4 simulation progress
 
- Got the Geant4/Root simulation package of PANDA (Proton ANtiproton at DArmstadt ,  GSI, Germany).
   PANDA is using fused silica slabs ( like DIRC@Babar) with PMT readout in the simulation.
   Allows me to compare how they have implemented the cerenkov detector (readout) in Geant4. 

- Started to add the Main Magnet support structure into QweakSimG4 based on (12/05/2004) Stan's SolidWorks drawings (elog)
  Geant4-Lession learned: only subtract simple bodies; incorrect visualization when using merge objects for subtraction .

That's all folks !
