RUN 191:

started at 1:20

Trigger MUST2, CATS1%3*10**3, CATS2%3*10**3
I=1.3uA
Purity = 20%

================================================
Several changed have been made during beam tuning:
  • Delay have been changed for CATS1-HF and CATS2-HF
  • One more CATS1-HF TOF measurement has been added. It's register in the spectra named NP_T_CATS1_HF
  • CATS division has been set to 3*10ł of both CATS1 and CATS2
  • Beam is made of 37Ca, 36K, 35Ar and 34Cl with in average 20% purity in 37Ca
  • CATS1 and 2 tripped because bottle of isobutane was empty. During changing the gaz bottle, gain of strip 13 X of CATS1 changed. Another calibration is probably need for this one
===============================================
NEW PHYSICS IS COMING
Fixede748 Thu Jul 6 20:07:46 2017 Daisuke + Thomas R+ Valérie LCHIOGeneralCD2Problem of counting on Chio
It seems that the ChIo is counting at a very low rate, around 100/s instead of 5000/s in previous runs.
Thomas R is called at 20h to fix the problem.
See scalers of Run 343 at 20h09.

Run stopped at 20:32, there is no bias on the cathode of the Chio, Thomas is entering the room.
HV on cathode put on again. CHIO should work better now...

During RUN340

13h10 The beam intensity dropped from 35 kpps to nearly zero. Iulian called PCP. They said they found the beam alignment was a bit off, so they were trying to realign the beam to get back the axis. We kept running the acquisition.
