|
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 ...

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.

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

Beam intensity is ~ 7.4 10^5 pps in CATS and 5.3 10^5 in VAMOS
~75% transmition

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 |

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.

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% |
