Run 296 start 19h52 stop at 21h51
e748 Exxx 3,1G 8 juil. 21:51 run_0296.dat.08-07-18_19h52m46s
MISSING STRIP, Y12 of CATS1, during the run, see plots Run296_CATS_Qraw.png and Run296_CATS_Qcal.png.
CATS 1 640V I ~ 0.16 ľA
CATS2 670V I ~ 0.14 ľA
Beam 10C around 10**5/s
Dead time between 7 and 13%
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) |
