|
Used data : Run 0284 & 0285 (about 4 hours data)
CsI energy calibration parameters are from previous experiment, optimized for deuteron
10C(p,d)9C
gate:
1. target gate by CATS1&2
2. deuteron gate by MUST2 dE-E
3. fragment gate by CHIO and plastic for Z=6,5,4
Ground state of 9C (bound) and first excited state of 9C (2.2 MeV, decay to 8B + p) are seen.
10C(p,t)8C
1. target gate by CATS1&2
2. triton gate by MUST2 dE-E
Not clear as (p,d) but sign of ground state is seen.
Kinematics is shifted for each telescope, probably because energy calibration and the position of the telescopes can be shifted.
Coincidence of alpha and (or) multi-proton can be helpful. |

Tests [V.lx) to be checked>>>] Online checkings of CATS efficiencies.
note that the Plast cannot be used directly for the control of CATS efficiencies in the online plots: Run296_plotPlastTcats.png
Plastics is counting nearly 65% more than CATS (cf Scalers +snapshot below zoomed on physical peaks). The Plastics also include secondary reactions and betas.
The correlation plots between the ionization chamber and the T_CATS_HF can be used, with suppression of the plot underflows. See plot examples.
In ICNumexo0_energy_Raw the integral is 8552. [Run296_ICenergyRawZoom.png]
The plot integrals are 7718 and 7841 for CATS1 and 2. [Run296_plotCorrelICCats.png]
The corresponding efficiencies are 90% and 92% for CATS1 and CATS2 (7718/8552 ~ 0.90 and 7841/8552 ~ 0.92) |
