There was a spark in TAndem at ~ 5.30 AM , HAkim came and said we will have a beam back at around 2 hours.

Sat Jun 17 13:12:26 2023, KWL GC, Problems, , Other, swap between 62Ni and 58Ni beam for run 6 and 7
|
Attached is the particle-gated gamma-ray spectrum for run 5 (green), run 6 (blue), run7 (red).
In run 5 we see clearly transition of 2+1 --> 0+1 in 62Ni, while in run 6 both transitions are visible from 58Ni and 62Ni (which is a result
of a wrong beam tunning in to increase the intensity during which the ion changed by mistake). Now we are running with 58Ni (run 7) and waiting for |

We see the the background lines coming probably from some activation inside the chamber as the target wheel is removed and we run only
with the alpha source at the moment.
The spectrum is the same means that something inside the chamber is activated, not the target 197Au used in the coulex run or neither it's |

test_noDSSD_62Ni_197Au.fast - run with the FC on, good for background (the beam was on but not on the target)
test_withDSSD_62Ni_197Au.fast - 58Ni beam on the target, E~210, intensity ~20 enA
test_withDSSD_62Ni_197Au_2.fast - 58Ni beam on the target, E~210, intensity ~20 enA |
