The clinical translation of FLASH radiotherapy (RT) requires challenges related to dosimetry
and beam monitoring of ultra‐high dose rate (UHDR) beams to be addressed. Detectors …

A paradigm shift is occurring in clinical oncology exploiting the recent discovery that short
pulses of ultra-high dose rate (UHDR) radiation—FLASH radiotherapy—can significantly …

FLASH irradiations use dose-rates orders of magnitude higher than commonly used in
patient treatments. Such irradiations have shown interesting normal tissue sparing in cell …

Objective. This work aims at characterizing LiF: Mg, Ti thermoluminescence detectors (TLDs)
for dosimetry of a 250 MeV proton beam delivered at ultra-high dose rates (UHDR). Possible …

Introduction Radiation-induced oxygen depletion in tissue is assumed as a contributor to the
FLASH sparing effects. In this study, we simulated the heterogeneous oxygen depletion in …

Purpose To characterize an experimental setup for ultra-high dose rate (UHDR) proton
irradiations, and to address the challenges of dosimetry in millimetre-small pencil proton …

Abstract Background A Faraday cup (FC) facilitates a quite clean measurement of the proton
fluence emerging from clinical spot‐scanning nozzles with narrow pencil‐beams. The …

Background Experiments with ultra‐high dose rates in proton therapy are of increasing
interest for potential treatment benefits. The Faraday Cup (FC) is an important detector for …

Objective. Ionization chambers, mostly used for beam calibration and for reference
dosimetry, can show high recombination effects in pulsed high dose rate proton beams. The …

Background. At the Center for Proton Therapy at the Paul Scherrer Institute (PSI) the delivery
of proton radiation is controlled via gas-based ionization chambers: the beam is turned off …
