 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. |
|
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. |

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. |
|
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. |
|
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. |
|
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. |

Thu Oct 6 11:45:39 2022, Nikolay Sosnin, Assembly Setup Days 1 and 2 25x
|
| Photographs of assembly up to the first pulser test with LiF3. |
|
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 |
