Low Energy Gamma Rejection Warren Lynch

Energy Dependent Range Discrimination For 2-10 keVee recoils. 1D, 20 Torr SF6 before and after diffusion. 1D, 200 Torr SF6 after diffusion. 3D, 20 Torr SF6 after diffusion. Where the Range cut is applied depends on the recoil energy.

Simulation Input 10,000 Electron Tracks from CASINO per Energy. 10,000 Fluorine Tracks from SRIM per Energy. W value: 35.45, quenching factor: 0.4. Randomized z between 11 and 48 cm to give diffusion of (116.2 μm / √cm)*√z . Perfect Energy Resolution. Zero Threshold. All tracks Isotropically distributed.

Next Include an Energy Resolution and Threshold. Include a better diffusion model. Include more statistics (>10000). Look for a better discrimination parameter if possible. Test for real?
