Wed Mar 4 11:00:57 2026, CLW, 35Cl(n,p) proton peak, run with 3 MeV neutrons over night
|
Plot from Fran showing peak around expected proton energy in both detectors. Top half are strips of detector placed at 180degrees wrt neutron beam, bottom
half 0 degrees. Hence, proton peak from bottom half should be at slightly higher energy.

Mon Mar 2 11:11:18 2026, FGI, TD, SB, CLW, Second configuration.
|
After the first weekend, we change the setup configuration. We removed the shadow cone, and we placed the chamber closer to the LiF target.
The voltage was increased upto 100V for both detectors, but there was a problem in DSSSD1. Therefore, The voltage was setup at 70V for DSSSD
#1 and 100V for DSSSD #2. |
|
Mon Mar 2 10:39:30 2026, SW, TD, SB, CLW, Detector SetUp. First Configuration 9x
|
The first sample on beam is the NaCl target #4. The shado cone was placed between the LiF target and the chamber.
The shadow cone was a cupper cilinder of 4cm diameter and 30 cm lenght, placed at 0.8 cm from the LiF target and 2.8 cm from the chamber. See
first figure 1. |
