|
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) |

Setup to be used: 1 dE (16 strips, 20 um thickness)
+ 1 E (16x16 strips, 150 um thickness. We have a spare for each thickness
Sample and detectors to be mounted on the same flange

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 |
|
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. |
