|
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. |
Fixed, e793s, Wed Mar 10 22:19:22 2021, Adrien, Freddy, Wilton and Nigel, OFFLINE, General, CD2, Offline analysis of run 51 and 52 using ganil files 
|
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? |

|
| Around 11:30 pm FAg value increased from usual 60-70 units to 140 units. It is suspected that MUGAST increased the trigger rate. |

Fixed, e793s, Thu Mar 11 02:50:14 2021, Ablaihan, Louis, BEAM, General, CD2, VAMOS transmition
|
| at 2h50 beam intensity reached 1.1x10^6 pps in CATS for 6.5x10^5 pps in VAMOS. The transmition decreased to 60% without any shift of the beam position. Does it come from a loss of efficiency of VAMOS at high counting rate? |

|
1) Some angular distribution were extracted (without any efficiency corrections) with gate on Ex btw 0 and 2 MeV (where p orbitals are populated) and btw 2 and 4 MeV (where f orbitals are populated). More counts are observed btw 110 and 120 degrees in Lab angle with the 0-2MeV gate compared to the 2-4MeV gate which is expected from the AWBA calculus. Kinematic cuts the large angles at high excitation energies. Geometrical efficiency is needed to compare this angular range. Looks like we well distinguish L=1 and L=3 transfers.
2) Some gamma spectra obtained with Ex gate btw -1 and 1, 1 and 3, 3 and 5 MeV.
3) Some strange horizontal lines are observed in the E-TOF id in MUST2. The spectra was obtained with gate on the promt signal in vamos so it can not be the beam intercepting directly must2...
4) the Ex vs Eg matrix |

|
at 4h15 CATS and VAMOS tripped probably due to too high beam intensity (~1.2x10^6 pps). We switched them on again at 4h30. All the 6 CATS in Board2 in HV by 525 V instead of 530 V.
We did not stop the run to not risk to crash the RCC. Events btw 4h15 and 4h30 will therefore have no time. |

Beam stopped 4h30 due to a equipment tripped in CSS1. They are going to fix it. Estimated timing of the intervention ~10/20min.
Beam went back at 4h52 at 3.5x10^5 pps in CATS and 3.0x10^5 pps in VAMOS. transmision ~ 85% |

|
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)
