Screenshots from MUGAST

The impact matrix looks fine but there are sectors missing but in the raw we see 13 sectors (instead of 16)

There E-Tof spectra missing because TY is either not working but we checked that TX is working --> TX should be used for MG2, MG5 and MG6
The ToF seems to have 2 components : one when MUGAST has triggered and one when Vamos has triggered.
We see alpha contribution that come from fusino-evaporation on Au that can go up to 120 deg backward.

We put the BT and HT screenshots as a reference

The cooling is at 0 degree.... there is not much alcohol left in the cooler, we will refill tonight.

When filling the coolers with alcohol the tracetek cable triggered and switched off water and supplies.
Beam is off

We have changed the range of the TAC FAG-HF to 500ns (it was 200 ns before)

there is no delay on the STOP of MUVI, it is directly the HF clean.

The inspection lines of MUVI1 are sent to vamos acquisition room.

PID with gate on T_FPMW_HF

The black points are what remains after putting the condition abs(T_FPMW_HF-13000)<1000, for MG1 and the annular.

RUN

run 138 - minutes of what happened during the run

Here is a brief summary of what happened over the course of the run:

From 4 pm to 12 pm (February 26th)
1. 20h00: call PCP because beam intensity decreased smoothly from 4e5 pps (16h) to 3e5 pps (20h) -> back to 3.5e5 pps
2. 20h25: call PCP because of sudden drop of intensity. VAMOS PF bias OK and beam OK according to PCP. Beam came back alone up to 3.2e5 pps with relaxation time of qbout 10 min as if some element was rumping up.
3. 23h50: FP_CATS tripped

From 12 pm to 8 am (February 27th)
Stable beam intensity at around 3.1e5 pps with VAMOS FP HV tripping 4 times

From 8 am to end of run (February 27th)
1. 08h05: FP_CATS0..5 tripped
2. 08h50: FP_CATS0..5 tripped
