Comprehensive characterization and validation of a fast-resolving (1000 Hz) plastic scintillator for ultra-high dose rate electron dosimetry. [PDF]

Med Phys
Abstract Background The normal tissue sparing effect of ultra‐high dose rate irradiation (≥40 Gy/s, UHDR), as compared to conventional dose rate (CONV), has attracted significant research interest for FLASH radiotherapy (RT). Accurate, dose rate independent, fast‐responding dosimeters capable of resolving the spatiotemporal characteristics of UHDR ...

Study of Cherenkov light lateral distribution function around the knee region in extensive air showers [PDF]

Serbian Astronomical Journal, 2015
The Cherenkov light lateral distribution function (LDF) was simulated with the CORSIKAcode in the energy range (1013 - 1016) eV. This simulation was performed for conditions and configurations of the Tunka EAS Cherenkov array for the two primary

Cherenkov radiation in a strong magnetic field

Physics Letters B, 2020
According to quantum electrodynamics, in a strong magnetic field that is constant and spatially uniform, the vacuum becomes polarized with a refractive index greater than unity.

Cherenkov radiation of light bullets [PDF]

Physical Review A, 2019
Electrically charged particles, moving faster than the speed of light in a medium, emit Cherenkov radiation. Theory predicts electric and magnetic dipoles to radiate as well, with a puzzling behavior for magnetic dipoles pointing in transversal direction [I. M. Frank, Izv. Akad. Nauk SSSR, Ser. Fiz. 6, 3 (1942)].

Cherenkov-Channeling radiation from sub-GeV relativistic electrons

Physics Letters B, 2019
Quantization of transverse energy levels for planar channeled relativistic electrons together with crystal dispersion may drastically change Cherenkov radiation resulting in mixed Cherenkov-Channeling Radiation (ChCR).

Cherenkov emissions for studying tumor changes during radiation therapy: An exploratory study in domesticated dogs with naturally-occurring cancer.

PLoS ONE, 2020
PurposeReal-time monitoring of physiological changes of tumor tissue during radiation therapy (RT) could improve therapeutic efficacy and predict therapeutic outcomes. Cherenkov radiation is a normal byproduct of radiation deposited in tissue.

Cherenkov radiation from electrons passing through human tissue [PDF]

Journal of Innovative Optical Health Sciences, 2017
A method for investigating the optical properties of human tissues is suggested. The method is based on the measurement of Cherenkov radiation produced by relativistic electrons passing through the tissue.

Sources of Low-Energy Events in Low-Threshold Dark-Matter and Neutrino Detectors

Physical Review X, 2022
We discuss several low-energy backgrounds to sub-GeV dark-matter searches, which arise from high-energy particles of cosmic or radioactive origin that interact with detector materials. We focus, in particular, on Cherenkov radiation, transition radiation,
