Investigation of inter-source and intra-source spectral variations in an electronic brachytherapy source using spectral measurements and Monte Carlo simulations. [PDF]

open access: yesMed Phys
Abstract Background The Xoft electronic brachytherapy source is commonly used to treat superficial lesions and tumors located at shallow depths. However, uncertainties in material composition and geometry, mainly arising due to the manual assembly of the x‐ray tube components, contribute to inter‐source variability in the tube output spectrum.

Effects of magnetic fields on HPGe tracking detectors [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2021
We present a study of magnetic fields effects on the position resolution and energy response of hyper-pure germanium detectors. Our results provide realistic estimates of the potential impact on the resolving power of tracking-arrays from (fringe) magnetic fields present when operating together with large spectrometers.

$$\alpha $$-event characterization and rejection in point-contact HPGe detectors [PDF]

open access: yesThe European Physical Journal C, 2022
AbstractP-type point contact (PPC) HPGe detectors are a leading technology for rare event searches due to their excellent energy resolution, low thresholds, and multi-site event rejection capabilities. We have characterized a PPC detector’s response to $$\alpha $$ α particles incident on the sensitive passivated and p$
