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

Med 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.

Evaluation of a CdTe semiconductor-based gamma camera for real-time dose dosimetry in boron neutron capture therapy. [PDF]

Med Phys
Abstract Background Boron neutron capture therapy (BNCT) is a cancer treatment that leverages the nuclear reaction between boron‐10 (10B$^{10}{\rm B}$) and thermal neutrons to generate high‐energy α$\alpha$ particles and 7Li$^{7}{\rm Li}$ nuclei that selectively destroy cancer cells while sparing healthy tissues.

X-ray and γ-ray Sensing from Aqueous-Based Lead Sulfide Telluride Nanocomposites. [PDF]

Small
PbSxTey nanoparticles integrate into flexible, size‐scalable aramid polymeric scaffolds, forming percolation paths capable of efficiently transporting the electrons and holes created by penetrating photonic interactions. The resulting nanosemiconductor‐nanofiber composite forms the basis for room‐temperature spectroscopic sensors of X‐rays and γ‐rays ...

Effects of magnetic fields on HPGe tracking detectors [PDF]

Nuclear 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]

The 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$

Operation of a high purity germanium crystal in liquid argon as a Compton suppressed radiation spectrometer [PDF]

, 2006
A high purity germanium crystal was operated in liquid argon as a Compton suppressed radiation spectrometer. Spectroscopic quality resolution of less than 1% of the full-width half maximum of full energy deposition peaks was demonstrated.
