In black the Kinematical line for states known to be populated strongly in 47Ti(d,p).
In blue range of the states of interrest.
The contamination is in a different region and should not cause any issue. |

|
We are currently working on the EX reconstruction which is off for detector 1, 3 and 7... One of our guess might be that there is an issue with the position of the detectors which gives error in theta... As the energy calibration is ok. Joined are :
- the Excitation energy for good detectors compared to all detectors,
- the theoretical kinematic line for the 3.57 state for each detectors,
- the excitation energy as a function of the laboratory angle (for this last spectra a clear dependency is visible for telescopes 1,3 and 7)
- the 3D view, which doesn't show clear problem in position... |

Testing changing the beam impact :
-Kine for beam impact = (0,0,0) for reference
-Kine for beam impact = (0,0,-5mm)
-Kine for beam impact = (0,0,+5mm)
-Ex vs ThetaLab for beam impact = (0,0,0) for reference
-Ex vs ThetaLab for beam impact = (0,0,-5mm)
-Ex vs ThetaLab for beam impact = (0,0,+5mm)
Red lines corresponds to Ex = 3.570 MeV and Ex = 4.070 MeV
To try to correct the problem i also offseted the beam in X and Y, but this doesn't solve the problem quite the opposite as it make the result worse for other detectors also... The fact that it is better at lower angle and worse at higher angle might mean that the detectors angles are tilted compared to the
surveyors measurments... I also tried to use the CAO positions for MG3 (see Detectors/mugast.detector) but it didn't solve the problem. |

By looking at the EnergyCalibrator.C, I saw that the extrapolation used to find the dead layer of aluminum is commented... This might be an answer to the problem... |

WE HAVE A SOLUTION!!! It seems that the order of the detectors in mugast.detector matters!! Now we start with a dummy MG8, then MG1, MG2, ... And everything is fine!! We think that is because it was taking the wrong calibration files (to be checked).
Joined are (for run 128,137,138,139,151,152,153):
-Ex vs ThetaLab
-Ex for all detectors
-Egamma vs Ex |

|
We have increased the pressure of VAMOS-IC from 50 mbar to 55 mbar in order to stop the beam in the pad n4 and not having few MeV of remaining energy in the pad n5.
Votage related:
HV(IC_wires) = 495 V
HV(IC_pads) = 165 V
HV(IC_cathode) = 1232 V |

Fixed, e744s, Thu Apr 11 14:03:45 2019, Valerian, CATS, Hardware, N/A, In case of a CATS2 tripped
|
Currently, CATS2 is inserted, if the window :
CATS2 has tripped appear, one should do the following :
- Open a terminal
- Type: HV
- Username is : admin
- Password is : admin
- Press enter twice
The list of channels is going to appear.
- Using the arrow of the keyboard, go down until you reach cats2
- then go right until you reach Off
- press space, the dectector should start ramping up
- If it trips again, you can try to put voltage to cats1 (right above cats2)
Two possibility :
- If cats1 trip it is the gas bottle that is empty call : 07 83 34 30 81 (Sebastien)
- If cats1 doesn't trip try cats2 again, and if it trips lower the voltage of cats2
To lower the voltage of cats2 : go to the left until you reach the first cell after cats2 name and lower the voltage 10 volts and try to start cats2 again.
THEN CLOSE THE TERMINAL |
