CsI energy calibration for MUST2 telescopes |
|
|
Calibration parameter for MUST2 CsI crystals are calculated with run1001-1006.
Attached are dE(DSSD)-E(CsI) plot of all the telescopes and parameters.
The parameter files are in
/home/e748/analysis/nptool/Projects/e744/Calibration/Energy/Calibration/CsI_rough
How to make the parameters;
For dE-E plot, the strongest locus should be proton.
Approximation formula for proton dE (Si 300 micrometer)-E (residual) I used is
(CsI_Energy) = -6.81774+41.1823/(Si_Energy-0.0814779).
Absolute value for the total energy may have some offset, but the gain of all the crystals should be roughly matched.
Maybe we need one more common parameter to adjust absolute value.
T2 Crystal #1 and #10 have no data. As I remember, this is the same as E748 exp. last year.
Crystals #9 for all the telescopes have low statistics. I'm afraid the mapping of crystal #9 is not correct.
->nptool/NPLib/Detectors/MUST2/TMust2Physics.cxx m_CsI_MatchingY[8]=48 but should be equal to 16 (corrected and re-compiled 27/05/2018). |
