RUN #2114 30 mai 2018 start @ 0h15; stop @ 2h58
BEAM STOP DUE to the shut down of the deviation element at the entrance of our D6 area.
target n°4. CH2 104 µm
All triggers, (no LISE)
Divisions CATS1 3. 10**4. PPT 3000 ; EXL 10**4
Evening shift team: Louis Valérie (Online)
Beam intensity around 10**5 pps decreasing to 80-70k pps around 1h30 then coming again to 95k pps at 1h40
Between 2h48 and 2h50 beam was decresaing down to few 1000/s on CATS, due to some alarms on the beam line, slowly increasing again after 2h52.
cf current of T4 around 13-14 µA Strong increase around 13 µA (due to the stabilization of the beam rate at 10**5 pps !)
------------------------------------------------------------------------------------------------------------------------------------------
NB: The E_TOF plots for MM1 and MM3 seem to count less than the MM2 and MM4 plots, nearly factor 10 below for MM1, and factor 5 below for MM3.
But the raw spectra for StrXT of MM1 and MM3 have quite the same statistics (see integral values) maybe some software problems.
Check how the TOF parameter is done in the offline (from XT or YT +thresholds and pattern conditions).
The same behaviour was seen in the previous runs. |
