Abstract

Lithium fluoride crystals have been routinely employed as passive radiation detectors based on radiophotoluminescence to assess the energy characteristics of the TOP-IMPLART linac proton beam during commissioning. This is achieved by leveraging their capability to record full Bragg curves through the stable formation of visible-light-emitting color centers in the LiF crystal lattice due to interactions with incoming protons. Here, a brief overview of the current state of this simple and powerful energy diagnostics method is presented, focusing on the latest improvements made to the theoretical model used for analysis. In particular, a new method to correct the analysis for systematic errors introduced by angular misalignment between the proton beam and the LiF crystal is presented.

期刊介绍： The journal seeks to publish papers that present advances in the following areas: spontaneous and stimulated luminescence (including scintillating materials, thermoluminescence, and optically stimulated luminescence); electron spin resonance of natural and synthetic materials; the physics, design and performance of radiation measurements (including computational modelling such as electronic transport simulations); the novel basic aspects of radiation measurement in medical physics. Studies of energy-transfer phenomena, track physics and microdosimetry are also of interest to the journal. Applications relevant to the journal, particularly where they present novel detection techniques, novel analytical approaches or novel materials, include: personal dosimetry (including dosimetric quantities, active/electronic and passive monitoring techniques for photon, neutron and charged-particle exposures); environmental dosimetry (including methodological advances and predictive models related to radon, but generally excluding local survey results of radon where the main aim is to establish the radiation risk to populations); cosmic and high-energy radiation measurements (including dosimetry, space radiation effects, and single event upsets); dosimetry-based archaeological and Quaternary dating; dosimetry-based approaches to thermochronometry; accident and retrospective dosimetry (including activation detectors), and dosimetry and measurements related to medical applications.
