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. |

|
Used data run run0284-0302 (almost all for 10C beam)
CsI calibration parameters are the same as E755 exp (deuteron optimized),
10C(p,d)9C
Gate:
1. beam position on the target by CATS1&2
2. deuteron gate by dE-E MUST2 T1-T4
Offset of the position of MUST2 T1-T4 was determined by 10C beam direct hit component. Target Z position (beam direction) is shifted 12 mm to match kinematics of 9C g.s.
Ground state of 9C and first excited state of 9C (2.2 MeV) are clear. Higher excited state around 6 MeV.
Statistics for T2 is smaller because 2 CsI crystals are not working (known before E755 exp,).
10C(p,t)8C
Gate:
1. beam position on the target by CATS1&2
2. triton gate by dE-E MUST2 T1-T4
Same position offset of (p,d) is used.
Ground state of 8C is clear, but energy of each CsI crystal seems to be shifted. |
