Collimator cave background

Bellow are some plots with the dose distributions in the experimental hall and the collimator cave which Pavel Degtiarenko produced using his GEANT simulation. His simulation is expected to provide more realistic production of neutrons in gamma(e) nucleus interactions. These plots correspond to a "standard" (2007-12-07) collimator cave geometry which is implemented in the GEANT simulation (a new geometry version with updated layout of sweeping magnets will come out soon).

• [2] - integrated dose distributions
