 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, |

|
Gafchromics foil was mounted on empty brass frame back to back with Li sample
Neutron beam goes well through the sample. Centered ~1 cm from sample center. Conclusion: no changes needed (too risky to make it worse and it
is ok now) |

Sun Oct 9 21:07:02 2022, Nikolay Sosnin, Boron Sample 3 Measurement 14x
|
21:15 Changed from detectors in-beam to boron-10 sample 3 in-beam (in-beam measurement got 1000 triggers, 500 of which were dedicated). The sample was
mounted identically to LiF 3. An attempt was made to replace the 20-micron dE detector with a 50-micron one, but the screwholes on the 50-micron detector
did not match the 300-micron E-detector ones and therefore could not be mounted. 20-micron detector was therefore re-attached. Planning to run for 12 hours |
