Cf252 Neutron and Gamma (no shielding) -- PE Counts
These are a comparison between Cf252 Neutrons and Gammas, placed 20.7 cm above the plastic scintillator slab, with no shielding.
Red = Neutrons Blue = Gammas
PE Counts, Unshielded Neutrons vs Gammas
Cf252 Neutron PE Counts: No shielding, Bucket, Bucket + Gd vial
Comparison between Cf252 Neutrons with no shielding, with shielding, and with shielding and Gd vial
Red = No shielding Blue = Shielding, no Gd Green = Shielding, with Gd
[there are clear inconsistencies here; I want to investigate more to see if this is still a result of the same issue I was encountering on Tuesday.]
