Leakage

Dead layer

Current json parameters is 663nm front dead layer and 4um on the back.

Run 1862

Re-investigation of thickness using the IFA009 setup. The relevant files are triple-alpha-SU_1862.

Done using GeometryCalibrator daf0d42 and DCalib 61956b

Position fitting

Starting from sorted files with a 100keV tolerance.

Hitpattern -l 1000 triple-alpha-SU_1862_*
IsotropicFitter -d setup/setup.json -i hist/h_*1862* -n SU -p chits/hit_SU -V

This gives

Center: (-0.475001, -0.588802, -38.0176)
 Err: (0.0250138, 0.0242563, 0.0717518)
