Modification of the Sandwich and DM geometry (04/Apr/04)

Changes

  1. Made the new geomery and mass for Sandwich.
  2. Made the new geomery and mass for Detector Module (DM).

  3. Checked the collision detection between the mass models.

    Sandwich -> O.K. (No overlapping)
DM       -> O.K. (No overlapping)

(1) Part of Sandwich

It is invisible to show the HV grids and the glue dots in the Red box (galaxy/vacuum). And also the CdZnTe array skips the display below the box, too.

We added the plastic shield and some lips around the sandwich module in the new geomery model. This geometry has included in the orginal SwiMM code.

(3) Check the geometery collision

Since then, we checked the overlapping between the mass models by using the collision detection software, DAVID. In this result, we made sure that the sandwich and DM model has no conflict.

(4) Future works

  1. Continue to check the geomtery overlapping for the larger modules.
  2. Set the top of the CdZnTe array at BATZ 0.35 [cm], correctly.
  3. Merging into the goro's SwiMM code, we will run the simulation in the case of Co57.
