Estimation of potential gain by changing. Files from this points are going to rubbish. Potential gains are c. 20%
22:04: The current acquisition window is recording for 2.9 s. And is not recording for 3.9 s. We are running currently with a spill cycle of 5s every repetition.
22:22 The spill cycle between each injection was changed to 4->3->2s progressively and FRS also stopped taking spills so we settled on 2s spill request.
In the morning the spill request has to be changed back to 5s when the FRS goes back into operation.
new file with the setting is

We stop taking beam at 10:47 for tuning a new setting.
Team PLEIADES is wanting to get access for 10 mins to install a remote oscilloscope, so entry to the ESR has been requested. |

Beam is back with some fluctuations.
We did not have beam from 9:34 until 10:08, around 35 minutes. |
