|
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. |

Run 37 stopped by itslelf at 15:43. This was noticed at about 16:10 by observing that grafana data rates do not change.
Stop at Run COntrol. LF looks disabled.
