No sign of the resonance during night shift. New run started but when operators are avaiable we will likely move to higher energies to try and
observe the (p,a) reaction. |

Fri Jun 14 14:52:02 2024, JM, Beam-Target Overlap Scan
|
The orbit of the beam in the ring was re-configured so that the beam position is more central.
With the target density at ~6e11 at/cm2 this allowed a target overlap scan using the beam lifetime to be performed.
Beam put into bunched mode to allow the number of particles to be observed on Grafana. |
