Shielding hut for GEM electronics

The main purpose of this study to determine the neutron-induced damage on electronics at the shielding hut for GEp.

Main drawings for the shielding hut are,

• 12GEp_Elevation [1]
• 12GEp_Iso [2]
• 12GEp_Plan [3]

Few extra details from Alan,

• The green boxes are cast steel 52" x 52" x 26".
• The distance between two green boxes are 96".
• There is a steel plates between two green boxes (bottom-2.5" thick & front-7.5" thick). The bottom plate allows for the front plates to match the height of the green blocks for stacking the top plates.
• And there is a steel plate (120" x 5" x 43") on the top (blue).

The drawings for the magnet support frame (by Alan) -[4]

The supporting frame and thesheilding hut were added to the g4sbs/src/G4SBSHArmBuilder.cc - [5], See under MakeHCAL.

And here the shielding hut and supporting frame appear on the g4sbs at the moment - [6]
