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) |

Nori | CATS | General | N/A | CATS tracking efficiency |
We noticed that the tracking efficiency was only 70% while the timing efficiencies were around 95%.
By lowering the thresholds (see Attachment 5-8) 89% tracking efficiency was achieved.
Note: analyzed run 293 (CATS1 640V, CATS2 670V), first 10000 events, only CATS trigger was selected. |

Daisuke, Freddy, Louis, Valérie | RUN | General | Cryo-LH2 | RUNS 318 to 320 |
From RUN 318 to RUN 320:
initial problem was that the stop process was not correctly taken into account on Narval. Geco acor was still running.
We killed Narval.
It was impossible to initialize or start run correctly.We did Several kna, kall.
Bugs on the run control server (ps -edf |grep narval or start_acq showed several on-going processes. We removed them). Then the CATS1 crate was not initialized correctly, it remained Offline.
see ProblemDAQcrateCATS1RCAt20h.png ProblemDAQcrateCATS1iolan.png
We rebooted (software mode on Iolan) CATS1 VXI crate, then init..;breakup...init then tried to start but stopped because because we noted merger problems.
See ProblemMergerCATSbranch.png
Then we needed to reinitialize a third time the Narval run control bto recover a correct Run control operation.
Fred S. came to check that we worked well... and that everything was working well. |
