Freddy | GRIT | Hardware | Cryo-3He | Timing change: -50 ns on CATS stop |
We removed 50 ns of delay to the CATS signal used for the stop of the TOF (CATS-MUGAST/MUST) because we were at the edge of the FAG.
See the attached picture for the current situation:
Green: MUGAST/MUST2 ORD

Stop comment:
* CATS1Y is not working --> We can't draw the CATS1 profile
* However we see scattering from CATS1 towards CATS2 in the shadowed region.
--> This means that the "thing" is most probably before CATS1 |

Valerian and Adrien | OFFLINE | Software | Cryo-3He | 3He-d kinematics |
To plot those kinematics, there is a macros called kine.cxx
The first plot correspond to the Silicon energy in MUGAST corrected for energy loss (some improvement might be needed)
Second plot is the same but without energy loss corrections (Raw silicon energy)
Third plot is the excitation energy of 47K |

mugast | RUN | General | Cryo-3He | Beam and cryo target |
The beam is fluctuating between 18 kHz and 22 kHz in VAMOS (24 to 27 kHz in CATS1)
Division on CATS1 trigger is 1000
Division on VAMOS trigger is 1000 in the GMT.
The target is stable with 6.00 K temperature, P=700mbar
We fill 4He every 5 to 5:30 hours and we use more or less 5.5 cm (i.e. 35l) for each filling.
The next bottle change is foreseen on wednesday morning.
We had 2 crashes of the target acquisition this afternoon. We think that it is due to the temperature. We added a fan and we slow down the reading of the temperature to every 12s (instead of 10s). |

Louis, Sylvain | AGATA | General | Cryo-3He | Run 56 : AGATA gamma rays in coincidences with VAMOS, MUST2 and/or MUGAST |
As attachment are some gamma spectra we obtained while trying several conditions on the run 056.
*Beam excitation has been investigated by gating on PID in VAMOS. Both 46Ar and 47K were selected. Excitation of 46Ar appears clearly while no clear conclusions could be drawn for the 47K.
*46Ar(3He,d)47K was investigated gating 47K in VAMOS and requiring an event in MUGAST (no specific gate could be performed on deuteron). Data size is very small but the maximum of the distribution is very close to the energy of the expected gamma ray from 47K.
*Fusion-evaporation of beam tqrget materials were investigated by requiring proton PID in MUST2. Due to the large number of possible fragments is not not possible to clearly identify the nature of the first to observed gamma ray. Yet the highest energy might correspond to a known gamma transitions in 87Zr in the case of fusion-evaporation with HAVAR window

Valerian | BEAM | General | N/A | Beam status |
Currently there is no beam since 22h-> Thunder + no more 48Ca sample. The sample was out during the night.
The "sourcier" on-call arrived at 8h15. By talking to people in shift at the PCP they told me that more will be known ~10am-11am. Beam is expected to be back around 12am.

In the CATS position spectra the central part is missing.
It is possible that the gain is two high for the actual high intensity of the beam. |

In the CATS position spectra the central part is missing (maybe for the high intensity of the beam?).
We can anyway recover the time information.
After the decrease of the high voltage of VAMOS drift chamber to avoid saturation of the signals
the BRho resolution has worsened of about 25% (see attachment). We will now increase it again (h. 22.30). |
