Performance of HPGe detectors in high magnetic fields [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2007
A new generation of high-resolution hypernuclear gamma$-spectroscopy experiments with high-purity germanium detectors (HPGe) are presently designed at the FINUDA spectrometer at DAPhiNE, the Frascati phi-factory, and at PANDA, the antiproton proton hadron spectrometer at the future FAIR facility.

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.
