Things to organise for the future:

- plastic detecor mounts to electrically isolate detectors

- storage boxes

Wiith the adjustments:

voltage and leakage current in dE are 7 V and 0.03 µA,  respectvely. (W1-20, 3186-9, 20 um)

voltage and leakage current in E are 47 V and 0.04 µA,  respectvely. (W1-150 3458-4, 144 um)

A logbook is attached to record what happened in the first weekend of the campaign, so as to keep track of the changes we made, before the 40K sample gets in. It will be updated tomorrow 15th Sept., 2024.

This is the energy deposited vs neutron energy plot of all ~220 runs of K40 and a few resonances can be seen.

October 22th. It's planned to remove the dummy sample on beam. We are planning to measured 4 references samples during the next two days.

- 6LiF #2. The 6LiF is deposited in the backing side. The measurement will be performed by using Al filter, Co - Mo- W and no filters.

- 6LiF #3. The 6LiF is deposited in the backing side. The measurement will be performed by using Al filter, Co - Mo- W and no filters.

-10B #3. The 10B is deposited in the frame side. The measurment will be performed without filters.

-10B #2. The 10B is deposited in the backing side. The measurment will be performed without filters.

For the moment 6 reference samples have been measured.

- 2 x 6LiF. The 6LiF is deposited in the backing side for both samples, #2 and #3. (Backing means the side from where the mylar has been glued)

- 4 x 10B. For the samples #1 and #2 the 10B is deposited in the frame facing the detector, and the samples #3 and #4 the 10B is deposited in the backing side.

During the last days, the two 6LiF samples will be measured, and the samples #2 and #3 samples with 10B.

I want to update about the DSSSD analysis and the processing routine. First, I attach a few screenshots of how the average signals work. Still, it can be improved looking at the average signal close to the gamma flash or optimizing the PSA parameters.

On the other hand, the data processing is already working. I attacha document where I explain the steps that must be follow and changes needed to make it work.

Two different runs of B2 and the DEED-EDET amplitudes.

Strip 13 ampltiude spectra for the LiF and B samples. Also a picture of a simulation of what would be expected in a 20 um detector in terms of energy deposition for several reactions (assuming a thin sample).

- for B-10 n,alpha, the dominant reaction is n,alpha_1, so just seeing one peak makes sense

- for LiF we would expect 2 peaks, one around 1 MeV and one around 1.8. In the data it looks more like 1 peak while the lower energy "peak" is likely noise. My guess is that the sample is quie thick, which leads to a lower energy alphas, and a lower energy triton. As a consequence, the two peaks merge.

Conclusion:

- check the other LiF samples to see if we have any thinner samples

- try and rotate LI sample to confirm that the direction we are using now is the correct one.
