Entry  Sat Mar 11 09:29:48 2023, EG, Other, , , current exeriment parameters as requested in the manual for shifters 

41_ge_single_theta 101,117,143 looks ok. No peakdeformation of 511, other gammas FWHM around half of that of511 - ok

ch4 in total rate EAGLE_0 arouns 2.1 kHz - ok

planger tollerace limits (green and blue horizontal markers) set far of the current distance, intantionally?

 

Entry  Thu Mar 2 16:40:45 2023, MP, Runs, , General, changing the plunger distance to minimum. 
Run 31 was stopped, because plunger distance is reduced to the mininimal one.
It takes time, in the meantime, after some break, run 32  was started, with no beam.
Entry  Sun Mar 5 22:32:56 2023, MP, Other, , , change of the target 6x

See pictures in the attachment:

1) stopper seen from the back (upstream view)

2) stopper  seen from the front (downstream view)

Mind the two small off-center dots. It is clear that the beam hits the edge of the frame.  This is possible because the 5 mm collimator has two small dots outside the 5 mm hole (the collimator  can be seen in the beam tube).

3) old target, upstream view

4)  new target, upstream view, after the stopper drove into it

5) new target, before it was mounted

6) the stopper, after the collision with the target. One of the visible rings is probably due to this collision, other traces probably reflect its complicated history earlier.

neda_psdcaen_positions.txt had weird values for three first detectors, especially neda_02.

It was:
NEDA_00_position_psdcaen    0
NEDA_01_position_psdcaen    0.22
NEDA_02_position_psdcaen    40

I (AF) make it:

Entry  Fri Mar 3 02:23:45 2023, GJ, Problems, , Software, builder gate, TS offsets run_0035_BU_lenghts.png
Data from current run - 35, with limited beam current and rates - see a recent post by Güray.
BU level, so what we see in Greware (both online & nearline).
Attached is the fold of Germaniums.
It seems way too large to me.
We are summing up the events and then, not surprisingly, having rubbish gamma-gamma matrices.
The gate is 1500 ns, while Ge are not so far away from each other.

Any fixed time differences should be corrected with LF configuration.
Having all Ge, ACS, and Neda TS-aligned at LF level, BU will do a good job with a reasonable short gate.

We need channel-by-channel TS differences.

The data we took and we are taking now can be recovered in terms of this correction later on.

Marcin can build the events correctly from LF level.
Let's try to do so with as short gates as possible and see again the gamma-gamma matrix and neutron-gated g-g 
matrix.
Entry  Fri Mar 10 08:02:39 2023, AM, Problems, , Beam, bigger data rate

Entry  Mon Mar 6 17:19:24 2023, OST, Problems, , Beam, beam unstable and a little high 

16:30 beam increased 5 mb/s to 9 mb/s and stayed 1 hour 9 mb/s

17:10 beam fixed. stable

Entry  Tue Mar 7 20:42:03 2023, IP, Problems, , Beam, beam unstable 

There was a problem with the beam from 20:19 to 20:30.

Now it is fine.

Entry  Wed Mar 8 07:30:15 2023, KS, KSz, Problems, , Beam, beam unstable 

The beam was unstable from 7:18 to 7:25.

Entry  Wed Mar 8 07:57:05 2023, IK, Problems, , Beam, beam unstable Screenshot_2023-03-08_08-17-41.png

The beam was unstable from 7:55. Stabilized around 8:03.

Counting rates are higher, EAGLE det4 went to ~2.5kHZ from ~2kHz (attached).

According to the operator, a bit of a tuning was done, current is 1nA.

 

run control = 48
