XStorm: A New Gamma Ray Spectrometer for Detection of Close Proximity Gamma Ray Glows and TGFs
Journal of Geophysical Research: Atmospheres, Volume 128, Issue 24, 27 December 2023., 2023 Abstract In this paper, we present XStorm, a gamma ray spectrometer developed to detect gamma ray glows and terrestrial gamma ray flashes (TGFs) in close proximity. Measurements are mostly planned to take place on balloon campaigns but also on the ground using bigger detectors.

Citizen Science Observation of a Gamma‐Ray Glow Associated With the Initiation of a Lightning Flash
Geophysical Research Letters, Volume 50, Issue 13, 16 July 2023., 2023 Abstract Gamma‐ray glows are observational evidence of relativistic electron acceleration due to the electric field in thunderclouds. However, it is yet to be understood whether such relativistic electrons contribute to the initiation of lightning discharges.

Nuclear‐medicine probes: Where we are and where we are going
Medical Physics, Volume 49, Issue 7, Page 4372-4390, July 2022., 2022 Abstract Nuclear medicine probes turned into the key for the identification and precise location of sentinel lymph nodes and other occult lesions (i.e., tumors) by using the systemic administration of radiotracers. Intraoperative nuclear probes are key in the surgical management of some malignancies as well as in the determination of positive surgical ...

Silicon photomultiplier‐based scintillation detectors for photon‐counting CT: A feasibility study
Medical Physics, Volume 48, Issue 10, Page 6324-6338, October 2021., 2021 Purpose The implementation of photon‐counting detectors is widely expected to be the next breakthrough in X‐ray computed tomography (CT) instrumentation. A small number of prototype scanners equipped with direct‐conversion detectors based on room‐temperature semiconductors, such as CdTe and CdZnTe (CZT), are currently installed at medical centers. Here,
