Comparison of Three Pulse Processing Systems for Microdosimetry

Three different pulse processing systems coupled to a tissue-equivalent proportional counter were tested in performance for various counting rates. The Tandetron accelerator at the McMaster Accelerator Laboratory was used to produce a mixed neutron-gamma field. Depending on the proton energy, different neutron and gamma dose rates were observed. The proton energy ranged from 1.8 to 2.5 MeV with the current set at 100, 200 and $300 \mu {\rm A}$. …
