Francois | BEAM | General | | No beam |
9H10: D5 stopped at 9H10. We asked for the beam.
9H48: Still no beam. There is a problem with the beam current limits set in the accelerator. They have to change it from 40 nAe between CO1 and CSS1 to 3.8 µAe after CSS2.
10H05: Still no beam. Vincent arrived for the air conditioning of D6.
10H23: No beam. They have to re-align the beam in the alpha line.
11H45: Beam is back after alignment of the entrance of the LISE line |

takeshi | TARGET | Hardware | | target temperature during warming up |
I would share the temperature log of the target cell during warming it up.
The thick line is the heat shield and the thin line is the cell.
The heat shield may takes 2 hours to reach 200 K and 6 hours for 270K.
Note that we need 45 minutes to evaporate liquid hydrogen before warming up. |

takeshi | TARGET | Hardware | N/A | start target cooling |
We started cooling the target cell at 13h03.
It would take 4 - 5 hours to cooling the cell enough low for liquifying hydrogen.

Fred, valérian, daisuke | DAQ | Software | N/A | Scalers to be recorded |
The U2M scaler data cannot be recorded to the data in the current version of Narval. So there were no scaler data during the measurement of 40Ca.
To resolve the situation, we added register parameters for specified channels of U2M. This allows us to record the counts of a given channel at each event.
Here is the procedure by Fred
---
dans l'onglet Parametres de l'U2M, créer un "parametre sur registre" en choisissant le registre U2M_SCALERS et l'item correspondant à la voie désirée (item 0 pour la première voie, item 1 pour la deuxième voie...).
Sauver la config DAS (donc attention à ce qu'elle soit entièrement correcte, notamment pour les MUVI ...).
Ouvrir le fichier action, ajouter "READ/PARAM=nom_du_parametre"
Suaver le fichier action puis le compiler.
INIT dans le Run Control.
Relanceer le online.
---
Notes:
- the parameter name should be 15 characters or shorter. If not, the compilation will take forever.
- More registers, more dead time. So we included only CATS, CAVIAR, Plastic, DT and 100 Hz clock. |

Faïrouz, daisuke | MUST2 | Software | N/A | MUST2 threshold from 1 MeV to 0.4 MeV |
It was found that the energy threshold of the strips was as high as 1 MeV. This threshold setting was chosen for the calibration and was never set back to the nominal threshold (0.4 MeV) for experiments.
Lowered to 0.4 MeV.
Note that due to the low energy threshold, triton of energies higher than 70 MeV were partially rejected during the measurement of 40Ca(p,t). |

takeshi | TARGET | Hardware | N/A | temperature log of the target |
We liquefied the hydrogen target around 22:00.
I would share the temperature log of the liquid hydrogen target during cooling and liquifying.
Black line is today and the other colors represent the references , The thicker liens are the heat shield and the thinner lines are the cell.
The behavior is almost same as the previous logs and seems okay. |
