Adrien | OFFLINE | General | CD2 | TODO LIST for Offline analysis | Miscelanous
- Cleanup branches in npanalysis (remove old vamos branch and add MW TDC ones)
- Check the MW TDC, make an offset calibration to align them
- Implement the calibration in the analysis and out a MW_T branch with all the time
- Allow for multiplicity in EDC
A clean macro for offline analysis producing a standardise Tcanvas to be put in the elog:
- Ex And Ex normalised with coinc gamma overlay (Tac conditions for both) Indicate the Sn on this plot.
- Kinematic plot with kinematic all line overlay (add fonctions to add kine line for 47Kdp 47Tidp 47Kpp 47Kdd 47Kdt 47KCC)
- Ex vs EDC
- Ex vs ThetaLab
- Gamma-Gamma
Angular distribution
- Add a separate macro with gate on gamma to produce ThetaLab distribution for each states
- Do a simulation and produce a Solid angle for the g.s. And apply it to the distribution
- Overlay the ADWA calculation with appropriate scaling (on a reference angle bin to be chosen)

Faïrouz, Juan Lois | AGATA | Software | CD2 | Problem with AGATA acquisition started at 4h40 |
There is a problem with AGATA Acquisition. All the bars in the global status & control are yellow!!!
This problem started at 4h40.
We called the acquisition astreinte but he doesn't know how to fix the problem.
We called Emmanuel but we got on the answering machine. We will call him again at 7 am.
The count rate of AGATA in the scaler looks ok: ~ 1200 |

Sarah, Louis, Charlie | BEAM | General | CD2 | Source is running out | The beam intensity spiked to 9x10^9, so Louis called PCP to ask them to reduce it. He was told that the source was almost depleted, and was presented with two options:
A) Keep pushing the source and run at 5x10^5, but run out completely soon (probably during the night shift)
B) Let the rates slowly drop and open the slits as much as possible, to make the source last longer (perhaps another day). This option is strongly preferred by the PCP team, and is the current plan we are following.
Changing the source would apparently take ~12 hrs. There will be a large meeting of all of the technical staff - including the beam and source experts - tomorrow morning at 09:00, so there may be more information about the best course of action after that.
Wilton was consulted as one of the spokespeople of the experiment, and he approves of this action. |

mugast ; valerian irene | OFFLINE | Software | CD2-Au | Issues in the EX reconstruction |
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. |

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 |

Franco | S1 | Hardware | N/A | Schema of the new S1 |
The signals of the new S1 will be splitted among 6 Mugast boards, according to the scheme attached.
The HV for the S1 have been updated accordingly, with labels like MG11/CsIMGXX. |

mugast (Adrien, Nigel et co) | BEAM | General | | Primary beam issues |
The secondary beam intensity has been fluctuating around 4 - 5 x 10**5 Hz most of the evening. 15 mins ago it was realised that it had dropped off to only 1 x 10**5 Hz. As suspected, PCP confirmed that primary beam intensity has dropped off. They are investigating ...
It would be good to have the TI (primary beam intensity) available to monitor here in the daq room. |
