VAMOS

new Threshold on DC1 Channel 127

Channel 127 of DC1 had a reduction of gain from yesterday, I corrected the gain by calibration and I reduced the threshold from 2114 to 2083 in order to reach the same low level.
(We can still see the lower gain in the online because the watcher is not reloaded, but it is ok in the root files)

TAC FPMW_HF in VAMOS was still out of range for MUGAST physics
We increased the range from 1us to 2us and applied a delay of 200 ns to the stop of the TAC.

TEST

Mon Feb 24 10:26:29 2020

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.

cout rate with no beam & water level check

Around 9 pm, we observed an average count rate of 30kHz on the "or agata" scaler rates panel of GECO. The other count rates were ok.
In the agata acquisition monitoring the rate was given about 8k. one of the detector was showing a rate in red.

We decided to stop : (1) to check the rates with no beam, (2) to check the water level in collection boxes and (3) the beam intensity.

Conclusions :

- The agata rate with no beam is about 4.5kHz. The rest seems ok.

- The level of water in the collection boxes did not change since 3 pm. So it should be ok for the night (see pictures)

- The beam profile and intensity are similar to what we got before

- The rate after we got the beam looks normal now.

So everything is going well Smile

PS : there is also a piscture about the water collection tank to empty the boxes if needed

crystal 12B counting rate is too low ~ 5 / s compared to an average of ~ 80/s - 100/ s for the other crystals
and 05B counting rate is too high from time to time reaching ~2000/s
but every thing is "green" ?!

Changes made in the electronic during the break between 14N and 14O

1) T_VAMOS-CATS1
it was not connected. We added 500 ns delay in CATS1 (CATS2 in reality) (48+150ns before)

2) T_CATS1_HF
range changed from 2µs to 200 ns

T_VAMOS-CATS1 is now connected in T_CATS1_CATS2 as posted this night. We have tried to add 500ns more delay (800ns in total) to CATS and it did not work, so we suspected the TAC or ADC. This is why we inverted T_VAMOS-CATS1 with T_CATS1_CATS2. For this TAC, CATS is the START (and is not delayed by 500ns).
