Field output correction factors using a scintillation detector

Medical Physics, Volume 52, Issue 6, Page 4844-4861, June 2025.
Abstract Background As small radiation fields play an ever‐increasing role in radiation therapy, accurate dosimetry of these fields becomes critical to ensure high quality dose calculation and treatment optimization. Despite the availability of several small volume dose detectors, small field dosimetry remains challenging.

Direct Annihilation Position Classification Based on Deep Learning Using Paired Cherenkov Detectors: A Monte Carlo Study

Applied Sciences, 2020
To apply deep learning to estimate the three-dimensional interaction position of a Cherenkov detector, an experimental measurement of the true depth of interaction is needed. This requires significant time and effort. Therefore, in this study, we propose

Coherent Radio Pulses From GEANT Generated Electromagnetic Showers In Ice

, 2002
Radio Cherenkov radiation is arguably the most efficient mechanism for detecting showers from ultra-high energy particles of 1 PeV and above. Showers occuring in Antarctic ice should be detectable at distances up to 1 km.

Study Cherenkov radiation by production of positrons and its annihilation in dense plasma focus

Results in Physics, 2019
The purpose of the current study was to evaluate the production of positrons through natNe2D4He18F, nuclear reactions and its possible Cherenkov radiation (CR) before annihilating in the hot and dense plasma medium (pinch) of a Mather type dense plasma ...

Numerical growth of emittance in simulations of laser-wakefield acceleration

Physical Review Special Topics. Accelerators and Beams, 2013
Transverse emittance is a crucial feature of laser-wakefield accelerators, yet accurately reproducing its value in numerical simulations remains challenging. It is shown here that, when the charge of the bunch exceeds a few tens of picocoulombs, particle-
