Back to CSR Weekly Meeting on 2011
- hyao: [cross section for Fe]
- xinhu: [Cross section comparison between left and right arm for 60 deg]
- xinhu: [Cross section comparison between left and right arm for 90 deg]
- xinhu: [Acceptance Plot Corrected]
xinhu:
- Acceptance region is so small that it may easily cause large error.
hyao:
- 90,120 deg has one constant scale factor offset between left and right.
- 60 deg, it seems wrong angle for left arm after first period or it may be caused by radiative correction because of different oriented target.
To do list:
xinhu:
- correct efficiency for the bad block , THaShower.C
- do the simulation of acceptance for the full region of NaI (box2 and box3) and check the efficiency correction for bad blocks of NaI
- and then calculate the cross sections for the left arm
hyao:
- Acceptance is independent of target. So recalculate the acceptance with turning off the radiative in SAMC.
- Compare the cross section of the right arm without/with pre-shower/shower cut.
- Compare cross section between two arms with gc cut only.
- Calculate the RC for previous cross sections to see the result.
- Find where constant factor is from for 90,120?
- Same figure on page 4/5 with only GC cut.
- Calculate radiative correction to pre-check.
