Revision as of 18:05, 21 November 2022

CaGaS Phase II (Capture Gamma Spectroscopy) is a repeat of capture gamma energy spectroscopy experiments performed during the summer of 2021 in the ISU clean room. The purpose of revisiting the capture gamma experiment is to use a new, higher activity 252Cf source (U2-622) and to investigate different thicknesses of Gadolinium foils and the effect on the high energy photon flux produced. This work is being performed in support of the main conversion process for the In-Situ Positron Annihilation Spectroscopy experiment being designed and performed by INL staff and external collaborators.

To Do

  • Measure up as close to Gd as possible and then ~12" away to calculate the adjustment factors necessary for coincidences
