JG found target off (target data stopped c. 02.30 this morning) and beam off (not re-enabled from previous CRYRNG area entry - target related?) JG re-enables |

15:30
Waiting for the target to cool down. ETA is 16:30 for cooling to be finished and then we need to try and make target.
While waiting we havve been running a background (R3). I noticed the rates on aida10 had increased (300k) and aida09 were slowlly creeping up |

Arrived at GSI.
We have 6Li1+ beam in the ring at 2 MeV/u. Injection is about 2.5e7 pps and lifetime with no target is about 40 seconds. We have injection every |

CARME_Sort histogramming has been updated to aid our understanding online.
> XY plots have been updated to reflect the true position of the beam relative to each detector. Online we will be able to layout in a grid
to reflect looking downstream in YR09 (see attachment 1) |

An MBS DAQ is running to collect two types of data:
1. WR timestamps for machine events (injection, target ON/OFF, ...)

Proxy bridge enabling anydesk and generic Internet access dropped due to atppc025 being rebooted. Found it dropped again late today.
Restarted bridge inside a screen session. |

Just after midnight on 20/04 it appears DSSD #4 leakage current has perfectly stabilised. See attached.
DSSDs remain biased.

|
D+D minimum energy Ecm = 150 keV which corresponds to Ed=150 keV/u or Ed=300 keV. Therefore we need a threshold below this.
Test 1 - Current status
Current slow comparator threshold is 0x64 (1 MeV). ADC data items rate in all FEEs is essentially zero with this threshold. (except aida03 and |

09:10
Arrived at GSI. Leakage currents status same as before, DSSD4 is still fluctuating. DSSD1 and DSSD3 currents are definitely lower again compared
to previous days. I am convinced they are decreasing over time, whether this will be enough for our measurement.... |

Came in to see the bias for DSSD4 which has been fluctuating for the past few days had tripped during the night. From the gnuplot it looks like
it was fluctuating all night and just after midnight it went above 20uA and tripped. |

Leakage currents this morning again appear to have lowered during the night. Current plot shows a day/night variation but I think the minimum
is decreasing ever so slightly. |

Arrived at GSI in the afternoon.
Found that the coolant loop on aida08 had popped out which resulted in the high FEE temperatures observed (see attachment 1). Female swagelock |

There appear to be issues with Shahab's caenlogging program. It crashes occasionally, with an error indicating the number of columns in the terminal
is incorrect. We will have to ask Shahab.
