Run 170
  • start: 8h07
  • start:
  • T_CATS_HF back to normal. Problem for run before remains unidentified. There was no change at all from our side.
Fixede755 Thu Jun 28 10:38:58 2018 FreddyMUST2GeneralN/AT4 Comparison of calibration runs
Attached is a comparison of two calibrations performed before the experiment (2 weeks and one day before) for Telescope 4 (the one having a degraded resolution in Ex on the offline).
One can see that:
  • The T4 resolution for strips X has been degraded between the two source runs.
  • The T4 resolution for strips Y remains ok and should be used for the analysis (slightly degraded only)
  • From the pedestal extrapolation, it also seems that there was a global drift for some channels.

Fixede755 Fri Jun 29 00:59:15 2018 LouisOFFLINEGeneralCryo-LH2Analysis of run 63 to 89 in 40Ca(p,t)38ca reaction
Here are some plot summarizing the analysis status on the 40Ca(p,t)38Ca channel.

Run concerned: 63-89
Running time: 18 hours

Gates applied:
  • Target Impact (from CATS)
  • Triton in dE-E
  • Incoming 40Ca, TCATS2_HF in [1600;24000]

Plots:
  • Cut applied
  • Kinematics, Exitation energy and llaboratory angle for two possible pics
  • Exitation energy per telescope for T1 to T4


Remarks:
  • There is no clear signal of ground state or any exited states
  • One can mybe distinguish pics correspond to different states but badly separated
  • During this beam time, Ionization Chamber was not working. Analysis of the 38Ca(p,t)36Ca reaction without this cut provide exactly the same shape of background. This background is probably due to fragmentation of the 40Ca beam in HAVAR foil, producing tritons undistinguishable from reaction tritond without cut on outgoing heavy ion.

    Other runs in 40Ca with the CHIO are probably needed to make good Ex reconstruction and tritons calibrations

starting tuning of 37Ca. Primary beam is too unstable. PCP machine tries to stabilize it (it should take less than one hour).
Fixede755 Fri Jun 29 12:39:34 2018 LouisOFFLINEGeneralCryo-LH2Analysis 38Ar(p,t)36Ar run 128 to 156
Here are some plot summarizing the analysis status on the 36Ar(p,t)34Ar channel.

Run concerned: 128-156
Running time: 31 hours

Gates applied:
  • Target Impact (from CATS)
  • Triton in dE-E
  • Incoming 36Ar, TCATS2_HF in [1600;24000]
  • Outgoin Z=18, delta_E E

Plots:
  • Kinematics, Exitation energy
  • Exitation energy per telescope for T1 to T4, with fit for two pics


Remarks:
  • We are able to distinguish two different states coressponding two known 0+ and 2+ states
  • By looking excitation energy telescope by telescope, we can see a shift between T1,2 and T3,4. Again, left right misalignement of MUST2 is highlight

    Runs in 26Ar will be helpfull for E tritons calibrations in CsI
Fixede755 Fri Jun 29 14:00:51 2018 takeshiRUNGeneralCryo-LH2summary for 38Ca + liq. H2, updated
I would summarize the statistics of 38Ca + liq H2 target measurement.
We have obtained the data of 49.5 hours until 28/6, and we added 3.5 hours more data last night.

See the spreadsheet for detail, such as the runnumber and the number of acquisition trigger.

Fixede755 Sat Jun 30 01:55:35 2018 Daisuke LouisRUNGeneralCryo-LH2RUN 191 FIRST PHYSICS RUN IN 37Ca
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*10³ 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
