| 14 bit card replaced for DEED 9-12, to prevent issue with pulser arriving before gamma flash. |

Thu Oct 6 11:07:47 2022, Nikolay Sosnin, Change of sample/Addition of pulser
|
Changed from LiF 4 to LiF 3 after running with LiF 4 overnight (run title on n_TOF DAQ was not updated to refelect the change, and still says LiF 4,
but the material setting of the run states correctly that hte run is with LiF 3).
Added pulser triggered from protons. 12 microsecond delay from protons to gamma-flash + 1.75 microsecond delay from gamma flash to pulser. 20 |

Thu Oct 6 14:58:29 2022, Nikolay Sosnin, Change of Pulser Delay
|
Still using pulser triggered from protons. 12 microsecond delay from protons to gamma-flash + 1.75 microsecond delay from gamma flash to pulser. 20 mV
pulser output into 50 ohm impedance (10 mV final output) of both polarities (using two pulsers, one NE pulser and one BNC PB5 pulser). Changed pulser setting
to run with 5 microsecond delay for approx. 1 hour, then change to 10 microsecond delay. |

Fri Oct 7 17:17:08 2022, Nikolay Sosnin, Change of Pulser Delay
|
Still using pulser triggered from protons. 12 microsecond delay from protons to gamma-flash + 11 microsecond delay from gamma flash to pulser. 20 mV
pulser output into 50 ohm impedance (10 mV final output) of both polarities (using two pulsers, one NE pulser and one BNC PB5 pulser). Changed pulser setting
to run with 11 microsecond delay for approx. 2 hour, then change to an overnight run with pulser running NOT triggered from beam. |
|
Fri Oct 7 20:04:30 2022, Nikolay Sosnin, Change of Pulser Setting
|
The pulser has been switched from triggering from beam trigger to running at a 10 Hz rate, and will now appear in random places in signal traces. Planned
to run overnight measuring LiF3, switch to empty + detector in beam in the morning. |

Sat Oct 8 11:56:49 2022, Nikolay Sosnin, Silicon Strips of Concern
|
DEED 6 and 9 no signal throughout the campaign.
EFED 27 high oscillations in baseline throughout the campaign. |
|
Sat Oct 8 11:57:36 2022, Nikolay Sosnin, Change of Detector-Target Separation 17x
|
Increased detector-target (LiF 3) separation by 1.5 cm. Had to replace the support strut under the detectors due to the previous one being fuly retracted
even for minimal target-detector separation. This change may affect detector rotation relative to the target. |
|
Sun Oct 9 20:57:54 2022, Nikolay Sosnin, Detectors in-beam, no target 12x
|
| After long beam-off, changed detector mount by moving it 2 cm forward into the beam, after removing LiF 3. |
|
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 |

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 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. |
