Wed Sep 27 09:54:06 2023, Emmanuel, 10B sample in
|
We switched from Aluminium target to Boron Target (number 1) on Tuesday (26th of Sept.). The Aluminium target was placed in the material room
by the RP. We will change to LiF (number 3) on Thursday (28th of Sept.) |

Tue Sep 5 16:09:45 2023, Emmanuel, Drop in gain for DEED 14
|
Dear all,
There was an issue with one of the strips of the deltaE detector (DEED 14), for run216644. The gain dropped to almost a factor of 3. Find attached.
Somehow, it was fixed, but still lags, when compared to other strips of deltaE. This was tested for a more recent run, run216651. Find attached. |

On the morning of Monday 14 August 2x RAL108 +/-15V PSUs were borrowed from the Edinburgh equipment in the ISOLDE hall to check whether the same transient
noise is observed at the +/-15V PSU outputs.

Fri Aug 11 16:50:58 2023, Nikolay Sosnin, EDET24
|
After inserting aluminium target, previously-dead channel 24 on EDET was re-plugged into a 12-bit card SPD02872. It is the only EDET on 12-bit card,
the rest are on 14-bit. From pulsers, there appears to be a 90 ns offset from this EDET to others, with EDET24 preceeding the rest. The last channel on
14-bit cards was broken, hence havng to use 12-bit. |

Fri Aug 11 13:16:56 2023, Nikolay Sosnin, E Front Incorrect Cabling
|
E front 2x16-way to 1x34-way IDC cable from the Junction Box to the IDC-Lemo 00 adaptor was found to be inserted upside-down - the 16-way IDC connectors
did not have polarisation keys - meaning the E detector p+n junction strip signals collected with 26Al for the first night are not working. Signals
from the dE p+n junction strips and E n+n Ohmic strips will be OK. The mistake occurred at the conclusion of the noise tests yesterday - see https://elog.ph.ed.ac.uk/nToF/52 |

Fri Aug 11 13:06:54 2023, Annie, Signal Spreadsheet info
|
Spreadhseet made for shifters to manually enter that they have checked each signal and that they can see gamma-flashes. It is saved as "26Al_EAR2_Signal_Checks.ods",
it is located on the second monitor on the right of the control room, next to the monitor used to see the beam intensity (same monitor used to see signals).
It will stay open throughout the campeign. Shifters have been told to check signals more than just the once to record that they're okay, |
