Title: Final Technical Report - Diamond Beam Monitor for Medical Dosimetry

Abstract

In this technical report we will discuss the efforts to develop diamond radiation detectors as dosimeters for therapeutic proton beam diagnostics, measuring the proton fluence as well as the beam profiles in high energy proton beams. The detector performance was recorded as the ion beam induced current (IBIC) from the 800MeV proton beam using different beam conditions. The lifetime of the detectors was also measured by monitoring the real-time detector response changes during the extensive proton irradiation. All irradiated diamond detectors were then characterized using synchrotron X-rays, by measuring the detector performance including I-V curves, response maps, flux scan and timing. The device performance decay was further studied with several simulation packages (SRIM\TRIM and FLUKA), and radiation damage mechanism was investigated by using experimental data and simulation models. Several impact factors (fluence rate, total dose, contact materials and cooling time) were discussed and the radiation effect on carrier transport was studied.
