Description
First estimate of inhomogeneity of thin silicon detector may be based on treatment of data used for energy calibration (acquired with very low statistics) saved in file
159.93.80.161:/home/LynxOS/mbsusr/mbsdaq/mbsrun/exp201804/data/calib/si_20_03_*.lmd
where alpha source was oriented to the surface of the detector under the angle ~90° at distance approximately 40 cm.
New measurement with high statistics is needed. Available data will be reported as soon as possible.

Estimation of the inhomogeneity of thin Si detector was done by script. The input data is root file converted from si_20_03_*.lmd. Then from this root file the file (sq20_calib_03.txt) with positions of the 7.63 alpha peak in 1mm SI in Left telescope after passing through the 20mkm of Si (SQ20) was obtained with analysis in ROOT. The procedure with fitting of the thickness of SQ20 was done with granulating of 1 mm detector by combining 4 X strips (32/4=8 ) and 16 Y strips. There is no data in Y strip 0.
