In this work the feasibility of using epitaxial (EPI) silicon diodes for clinical dosimetry was studied with a Siemens Primus Linear Accelerator from Sírio-Libanês Hospital. Three samples of EPI diodes were investigated, concerning the influence of pre-irradiation on their response as on-line clinical photon and electron beam dosimeter. All measurements were performed with the diodes unbiased, operating...
The rad-hard EPI diode was characterized envisaging its application in on-line 1.5 MeV electron beam dosimetry in radiation processing. As expected from a current sensitivity loss (13.5%) to the accumulated dose up to 750 kGy, the EPI diode exhibited good short-term repeatability (CV = 1.9%) which is better than that required for CTA dosimeters, routinely applied in radiation processing. The dose-response...
