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

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
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
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
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
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 ...

• 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 ...

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 ...
