Faïrouz, daisuke | MUST2 | Software | N/A | MUST2 threshold from 1 MeV to 0.4 MeV |
It was found that the energy threshold of the strips was as high as 1 MeV. This threshold setting was chosen for the calibration and was never set back to the nominal threshold (0.4 MeV) for experiments.
Lowered to 0.4 MeV.
Note that due to the low energy threshold, triton of energies higher than 70 MeV were partially rejected during the measurement of 40Ca(p,t). |

Check regularly the HT on the MUST2.
NB: without beam the current on Telescope 4 is high, between 9 and 11 µA. see snapshot.
NB: The Ioset was increased at 20 µA on Friday 25th (cf Id entry=490) to avoid trips on this telescope due to strong intensity fluctuations due to the beam. |

change of HV on CATS during Run 345: from 650V to 670V
Current on CATS2 is fluctuating (from 0.12 µA up to 0.6 µA) at oscilloscope, signals remain correct.
At 670V it is better for CATS2 efficiency
See plots : run345_EnergyChioRawTsdiff.png and run345_correlDeIChiotofCatsHF.png
Integral for IC is 8075; integral of the physical events in IC DE versus TOF CATS1 is 7548; for CATS2: integral 7044.
We have a rough estimate of CATS efficiencies: 7548/8075= 93%, for CATS2 87%.
The counting rates on CATS have closer values (at 650V, CATS2 is at 130 k pps; at 670V rate is 170k pps)
CATS1: 190k pps
CATS2: 170k pps
Plastic: 175k pps

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) |
