Development and application of a novel scintillation gel‐based 3D dosimetry system for radiotherapy

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 3, March 2025.
Abstract Purpose This study introduced a novel 3D dosimetry system for radiotherapy in order to address the limitations of traditional quality assurance methods in precision radiotherapy techniques. Methods The research required the use of scintillation material, optical measurements, and a dose reconstruction algorithm.

Quantum Cherenkov radiation and noncontact friction [PDF]

open access: yesPhysical Review A, 2013
We present a number of arguments to demonstrate that a quantum analog of Cherenkov effect occurs when two dispersive objects are in relative motion. Specifically we show that two semi-infinite plates experience friction beyond a threshold velocity which, in their center-of-mass frame, is the phase speed of light within their medium.

Results and prospects on registration of reflected Cherenkov light of EAS from cosmic particles above 10^{15} eV

open access: yes, 2014
We give an overview of the SPHERE experiment based on detection of reflected Vavilov-Cherenkov radiation (Cherenkov light) from extensive air showers in the energy region E>10^{15} eV.

Generation of incoherent Cherenkov diffraction radiation in synchrotrons

open access: yesPhysical Review Accelerators and Beams, 2020
Incoherent Cherenkov diffraction radiation was recently produced in the Cornell electron storage ring using counterpropagating beams (electrons and positrons) passing in the close vicinity of a dielectric made of fused silica.

All-fiber femtosecond Cherenkov source

open access: yesEPJ Web of Conferences, 2013
An all-fiber femtosecond Cherenkov radiation source is demonstrated for the first time, to the best of our knowledge. Using a stable monolithic femtosecond Ybdoped fiber laser as the pump source, and the combination of photonic crystal fibers as the wave-

Enhanced Cherenkov radiation in twisted hyperbolic Van der Waals crystals

open access: yesInfoScience, Volume 2, Issue 1, March 2025.
Efficient Cherenkov radiation over a wide range of momenta is highly demanded for many applications but still remains a challenging task. Here, we demonstrated that twisted hyperbolic Van der Waals crystals enable enhancement of Cherenkov radiation in a broad range of wave vectors.

Detection of Atmospheric Cherenkov Radiation Using Solar Heliostat Mirrors

open access: yes, 1996
The gamma-ray energy region between 20 and 250 GeV is largely unexplored. Ground-based atmospheric Cherenkov detectors offer a possible way to explore this region, but large Cherenkov photon collection areas are needed to achieve low energy thresholds ...

Consensus statement on the exploration of clinical translation and application of electron ultra‐high dose rate FLASH radiotherapy

open access: yesPrecision Radiation Oncology, Volume 9, Issue 1, Page 4-12, March 2025.
• FLASH‐RT as a novel irradiation technique shows a protective effect on normal tissues while maintaining comparable tumor killing effect as CONV‐RT, also known as the FLASH effect. • We develop a consensus statement on the exploration of clinical translation of FLASH‐RT, and provide insights for the further application of this technology in clinical ...

Recent Advances in Strategies to Enhance Photodynamic and Photothermal Therapy Performance of Single‐Component Organic Phototherapeutic Agents

open access: yesAdvanced Science, Volume 12, Issue 7, February 17, 2025.
Single‐component organic phototherapeutic agents (SCOPAs) for photodynamic therapy and photothermal therapy hold promise in treating diseases. This review delves into strategies for enhancing SCOPAs performance, such as boosting ROS generation, improving the photothermal conversion efficiency, and summarizes potential synergies with other therapeutic ...
