Plunger chamber closed, some dummy target and stopper probably inside

run 72    eagle closed

run 73    right half of EAGLE completely opened

Three screenshots are attached:

Run 72  EAGLE closed

1)  Three rings.  There is significantly more 511 in ring 143 than in 117, 101

2) 5 detectors of ring 143. They all look similar to each other.

Run 73  right half of EAGLE opened

3) 5 detectors of ring 143.  The 3 detectors in the opened half hardly see 511 keV, the other 2 do.

Check with Colibri and a gamma scintillator probe ws done: largest activity is visible close to the target chamber, in the region starting at the edge of the chamber, end ending about 6 cm upstream.

About 80 gamma counts/s are seen there. The count rate decreases further upstream.

Background rate:  20 to 30 counts/s, 25 counts/s in Sala Fizykow.

Radioactivity line seen in the spectra,  with the same behaviour as 511:   743.5,  936 keV, 1434 keV.  These are lines from 52Cr, fed by beta+ decay of 52Mn.

Confirmed by Michain gamma-gamma.

52Mn can be produced in the a2pn channel in  the reaction 32S+27Al

Attached are the lists of files copied to the two 4 TB Bahadir's disks.

run 66 started, radiocativity (background)

At about 12:00, 13/03/2023 (about  17 hours after the beam was stopped), a measurement of activity of the beam line was performed using  FH 40G-L10 meter.

Radioctivity run 65 stopped before the measurement, radioactivity run  66 started after the measurement

Background level 120 ns/h

Target, stopper, the forward half of the target chamber - dismounted.

Approximate distance from the target position (upstream), approximate activity

10 cm    500 ns/h

25 cm    420 ns/h

35          350 ns/h

40          350 ns/h

50          200 ns/h

75          170 ns/h

Plunger run files for later to calculate error in the distance

started

source in the target position, as precisely as possible

target and stopper and beam dump dismounted.
only the constructional elements of the plunger remained. 

pure background, g trigger only.

Michal says the"bg" spectrum did not change...

Run 59 collected data using gg trigger radioactivty

Run 60 trigger changed fropm gg to single g.

Just in the beginning a few minutes gg data could have been collected.

18:54 Run 58 stopped and 18:55 Run 59 started.

BEAM STOPPED.

END of EXPERIMENT.

Run 59 collects radioactivity.

For a split second a red "NO DATA" notification appeared in the top right corner of Counting rates dashboard.

It looks like it did not change anything in data collection.

Beam stable, counting rate within limits, plunger distance within the given tollerance, gamma spectra ok, everything looks good but....

(yes there must be some "but"), refreshing of EAGLE_array_monitor.mat and NEDA_array_monitor.mat are out of sync. Mostly pure red colour is dysplayed. Not very usefull and (I suppose) missleading information.
