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.

|
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

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
