We observe a change in the Brho of VAMOS : the charged states are divided in 2 !!!

Édit: it is now understood as ice water cracking on the upstream of the target.

Fixede786s Mon Jun 24 06:14:02 2019 LouisOFFLINEGeneralCryo-3HeOffline analysis 46Ar(3He,d)47K for run 49
Energy loss vs. Time of Flight identification has been performed in mugast. On can notice some calibration trouble in energy and time. Big shift of the deToF bananas are seen from one telescope to an other. Furthermore, one can distinguish proton and deuteron in MG1, 3 and 4 but it's it's very difficult to conclude for 5,7 and 11.

From those plots, deuteron has been selected. Adding a cut on the center of the CATS profile and on the Brho in vamos, energy and angle in the laboratory has been computed. And then the excitation energy. Nothing clear for the moment...

a macro "Get46ArHe3d.C" which apply cuts and generate a new tree with only gated event is written in:
/home/mugast/analysis/nptool/Projects/MUGAST/macros/e786s
the generated tree "46ArHe3d.root" contains only event which passed cuts.

cheers

* CATS1Y is not working --> We can't draw the CATS1 profile
* However we see scattering from CATS1 towards CATS2 in the shadowed region.
--> This means that the "thing" is most probably before CATS1

The beam is fluctuating between 18 kHz and 22 kHz in VAMOS (24 to 27 kHz in CATS1)
Division on CATS1 trigger is 1000
Division on VAMOS trigger is 1000 in the GMT.


The target is stable with 6.00 K temperature, P=700mbar
We fill 4He every 5 to 5:30 hours and we use more or less 5.5 cm (i.e. 35l) for each filling.
The next bottle change is foreseen on wednesday morning.

We had 2 crashes of the target acquisition this afternoon. We think that it is due to the temperature. We added a fan and we slow down the reading of the temperature to every 12s (instead of 10s).

Fixede786s Tue Jun 25 03:44:12 2019 Louis, SylvainAGATAGeneralCryo-3HeRun 56 : AGATA gamma rays in coincidences with VAMOS, MUST2 and/or MUGAST
As attachment are some gamma spectra we obtained while trying several conditions on the run 056.

*Beam excitation has been investigated by gating on PID in VAMOS. Both 46Ar and 47K were selected. Excitation of 46Ar appears clearly while no clear conclusions could be drawn for the 47K.

*46Ar(3He,d)47K was investigated gating 47K in VAMOS and requiring an event in MUGAST (no specific gate could be performed on deuteron). Data size is very small but the maximum of the distribution is very close to the energy of the expected gamma ray from 47K.

*Fusion-evaporation of beam tqrget materials were investigated by requiring proton PID in MUST2. Due to the large number of possible fragments is not not possible to clearly identify the nature of the first to observed gamma ray. Yet the highest energy might correspond to a known gamma transitions in 87Zr in the case of fusion-evaporation with HAVAR window
