To do list
Monday
- ask final beam energy�for the 14O beam (include CATS removal)-> E=7.50 MeV/u
- Mount CATS timing (much thinner) at Cats1 position
- make a hole target, diameter = 7 mm, thick target (Al?)
- dismount targets with gloves due to the contamination
- mount targets (list ..� + hole target)
Target list ( Hole Target, 200 um CH2 (?), 100 um CH2, C target, 100 um CH2, 70 um CH2 )
- remove the Vamos entrance DCs
- install the VAMOS finger, larger one
- Id plots with Vamos
- to mount / or not a MCP
- Prepare Agata Or - HFpropre and Agata 52 � HFpropre for beam intensity monitoring.
- Solve the MM3 EY problems (see previous elog entry)
- Understand Vamos (40% efficency) and Agata efficiency (5% efficiency Agata instead of 10%) for 2H(16O,p)17O
- Make an acq run with Mugast in air to understand if detectors contaminated

Attached you can find the PACE4 calculations for the reactions 16O + 12C and 16O + d at 6 MeV/u beam.

Main cross sections are:
* 25Mg (232 mb, 25%) and 16O (182, 21%) (for 16O+12C).
* 17O (292 mb, 42%) and 14N (270, 39%) (for 16O+d).

Hardware

The Ovv error shows on the -5V (first one) of the 3 board (5,3.3,10V for MUST2�squares)
It means that the voltage is over the asked value.
If we ask 5V, we get 5.5V in reality

We changed for 4.5V and we get 5V. The current is different from the one on the MUGAST BT box but we don't know how many detectors are connected.
We exchanged cables and found the same current in the other board, so we guess that it is still working properly.
A check of stability should be done.

Overview nightshift run 112

Smooth night, everything was working properly.
Checked agata rootfile to see preliminary gammas.

19Ne 275 state observed

Also 19F (strong 109 state) (fusion-evaporation?)

Check Agata elog for more details.

RUN

Overnight run259 crashed during the night

N/A

Run 259 which was an overnight run crashed (During the night between the 6 and the 7th of April).

The result of this crash was that the the acquisition started writing a 4gb file each seconds for 80 seconds. We then had to remove the run (~300gb) as the quota allowed by GANIL to the mugast account was reached.
We also transfered the output of the Nptool analysis to the /data/evamosX/com2019/Analysis/nptool_outputs/ and made a symbolic link to this folder in the nptool/Output in order not to ever reach the quota again (Antoine seems to have no quota, or at least multiple Pb of quota...)

Hardware

During Run 129,
1) investigation of the trapezoidal filter of IC
2) The Conclusion is that if we reduce the shaping to 2.5 us we reduce the random line in IC vs IC (At 1e5 in VAMOS : Random Line / Peak is 18.5 % compared to 40% for shaping of 3us)
3) The 2.5us us also optimum for the resolution (oscillation of the abse line after the filter very sensitive to K, with freq of ~500Khz)

1) A high energy gamma has been identified at 3505 keV by gating on 3-5 MeV range in excitation energy. This transition is unknown so far

2) preliminary angular distribution has been extracted for the p states(<1MeV) and the f states (3-5MeV) corrected from geometrical efficiency. Angular distribution with gate on the 3.5 MeV gamma was also extracted. Too few statistics to tell anything. Need at least 4 time more statistics to have a proper angular distribution.

Offline analysis of run 56 has been perfomed. On plots, kinematics lines and excitation energy are shown using gate on 47K in vamos. Then agata spectra is shown using gate on 47K in VAMOS un valid event in MUGAST. One can (may be) distinguish a peak at 368keV...

Offline analysis of run 51-61

Sat Mar 13 10:11:44 2021

Run 51 to 61 are converted and analysed.
I fixed the gamma/no gamma normalisation after binning change.

We clearly see :
a state at 2.5 MeV that decay directly to the g.s. and a state at around 5 MeV with a 3 gamma cascade.

To do list:
- Add an angle dist in AngDist.C macro for the states around 2MeV (you can remove the Ex plot)
- Put Logy in all the canvas for the angle dist;)
- create a new macro showing the EDC 1D histo gated on several sliding windows in Ex to see the the gamma peak changing height
- add arrow or line indication the gamma rays position on every plots
- build the level scheme based on this (there is a preliminary scheme posted earlier by Manu based on gamma-gamma).

Offline analysis of run 51 and 52 using ganil files

CD2

We noted that the gamma ray efficiency calculated from file converted from AGATA was close 100%. We concluded that the conversion program was reauiring a gamma ray to be present.

This is confirm by analysis of the ganil dta file that show 10 time more count that the agata one.

Here is a kinematical plot of the run 51 and 52 analysised from ganil file.

There is a 1.5MeV state present that disappear in the agata coincidence. This is to be investigated with more data. Is it an isomer state? from 48K? 48Ti?
