We implemented the add-back correction with cross-talk subtraction.
On the joined graph, RawEnergy correspond to the sum of the energy in every crystals and Energy correspond to the sum of energy in every crystals with the cross subtraction. |

|
To use the remote settings of the Mesytech modules :
- start GANP170
- login: .\invité | pass: ganil17
- start putty
- select serial
- in host name type COM# (# is the number of the port which seems to be chosen at random at every reboot).
- when you have found the good port number, a terminal will appear, in this terminal you cannot erase, so if you type something wrong press enter.
- type :
off
the red LED of the front panel of one of the mesytech should stop, now, you know which mesytech is controlled by the terminal you opened.
- type:
on
the red LED is back again and remote control is working again.
- to list the parameter type:
ds
- the parameter of interest are under "rc settings"
You can then follow what's written in the manual next to the PC. |

Target -> Thick target (Sandwich target ??)
The predictions are different....
At large angles, the 5/2+ peak (at 2.78 MeV) is cut because it goes to lower energies in lab. If the background at 4 MeV is normalized to the one at 0°, there is no very broad-resonance at high energy in large angles. |

Ongoing, e744, Sat Apr 28 10:17:22 2018, Valerian and Iulian, MUST2, Hardware, 3-alpha, Status of MUST2 telescopes 27/04/18
|
Yesterday night we tested T1, T2, T3, T4, T5, and T6.
All telescopes (except T6 which still have a "tripping" CsI) have an Energy and Time signal on X and Y!
Joined is the final results with every working telescopes.
T5 is now placed in 0 degree chamber cabled with the cables corresponding to telescope 5, except the BT which is the one from the unused T7
(BT for telescope 5 didn't work). |

Ongoing, e744, Sat Apr 28 13:27:26 2018, Valerian and Iulian, MUST2, Hardware, 3-alpha, multiples runs with two alpha source on T1 T2 T3 T4 and T5
|
For the following runs we will use two 3 alpha sources :
On T1, T2, T3, and T4 : 11615 : Flux = 1496 alpha in 2 pi
On T5 (at 0 degrees) : 11616 : Flux = 1603 alpha in 2 pi
runs #170 - #181 were debugging runs.
Issue were found :
- T6 gives a lot of ORD with or without HV ON.
- If a stop is added to MUVI2, there is an energy shift of the alpha peaks. This behaviour can be seen in run 172.
run #182 is a good run. With both 3 alpha sources and no stop on any of the MUVI cards.

|
There is an issue with the GMT slave. When you click Online and then apply write hardware, if the message : register error on GMTSlave appear, reload a functioning DAS config and do not write hardware twice.
If you use write hardware twice, the error will disappear, but almost no triggering of the GMT will occur. |

Ongoing, e744, Fri May 25 02:57:44 2018, Valerian and Iulian, OFFLINE, General, CH2, Simulation Azure 1H(14N,p) and measurement
|
We can know conclude without any doubt that we were able to measure resonances from 1H(14N,p)14N. The resolution with a rough analysis and the current bad calibration is around 180keV in the com.
Identification of resonances is still difficult but some structure seems consistent with previous works. Also, at higher energy there are only few measurement so the data taken with 14N this night should be interesting.
First spectra is simulated with AZURE2
Second spectra is Energy in center of mass for ThetaLab between 0 to 4 degrees (T5)
Third spectra is Energy in center of mass for ThetaLab between 2 to 3 degrees (T5)
Fourth spectra is Energy in center of mass for ThetaLab between 10 to 12 degrees (T1-T4)
Fifth spectra is Energy in center of mass for ThetaLab between 15 to 20 degrees (T1-T4) |
