High energy femtosecond fiber laser at 1018 nm and high power Cherenkov radiation generation
… fiber laser system generating 4 W of femtosecond Cherenkov radiation at that wavelength was built. The characteristics of the Cherenkov radiation were well studied.

A classical view of the quantum vacuum
… charged particle moving through a medium emits Cherenkov radiation when its velocity exceeds the phase velocity of light in that medium. Under the influence of a strong electromagnetic field the nonlinear nature of the vacuum allows for the possibility of high-energy particles to radiate via the …

Metamaterial structures for Wakefield acceleration and high power microwave generation
… and simulated. The novel phenomenon of reversed Cherenkov radiation has been found to enhance the beam-wave interaction in metamaterials. A metallic wagon wheel metamaterial structure was designed and built for use in an experiment at the Argonne Wakefield Accelerator (AWA) Facility. On the …

Commissioning the DIRC Detector and Searching for Axion-like Particles at GlueX
… of the strong nuclear force. The GlueX DIRC, a Cherenkov radiation-based detector, was proposed to upgrade the particle identification capability of the GlueX experiment, which aims to perform quantitative tests of Quantum Chromodynamics in the nonperturbative regime by searching for and …

Design, optimization, and applications of few-cycle Ti:Sapphire lasers
… technologies (broadband zero-GDD mirror sets and Cherenkov radiation in the few-cycle regime) which are developed to increase the repetition rate and spectral coverage of the laser systems operated in the few-cycle regime. Fiber-optic Cherenkov radiation in the few-cycle regime excited by sub-10fs …

Sensitivity of an expanded inclusive search for MiniBooNE-like excess in MicroBooNE data
… Some particles are too low velocity to generate Cherenkov radiation in a MiniBooNE-like detector. Therefore, MiniBooNE-like cuts were used to search for the specific topology of one Cherenkov-visible shower and zero Cherenkov-visible muon tracks to simulate the MicroBooNE Monte Carlo coming out …

Nonlinear Dynamics of Vortices in Different Types of Grain Boundaries
… resistivity of grain boundary. We found that Cherenkov radiation of rapidly moving vortices in grain boundaries can produce a new instability causing generation of expanding vortex-antivortex pair which ultimately drives the entire GB in a resistive state. This effect is more pronounced in …

R&D of a High-Performance DIRC Detector For a Future Electron-Ion Collider
… Detection of Internally Reflected Cherenkov light (DIRC) detector design. The passage of a high energy charged particle through a fused silica bar of the DIRC generates optical Cherenkov radiation. A large fraction of this light propagates by total internal reflection to the end of …

Artificial engineered materials for novel accelerator applications
… to be used for the generation of reverse Cherenkov radiation. The proposed initial design exhibits a left handed TM31-like mode at 5.5 GHz with a R/Q of 6.6 kΩ/m and a shunt impedance of 10.9 MΩ/m, indicating strong beam coupling, this is verified by the strong longitudinal wake impedance …

A Dark Matter line search using 3D-modeling of Cherenkov showers below 10 TeV with VERITAS
… focused on the latter method. The Very Energetic Radiation Imaging Telescope Array System, V ERITAS, is a telescope array that detects Cherenkov radiation. Theory predicts that DM particles annihilate into, e.g., a γγ pair and create a distinctive energy spectrum when detected by such telescopes, …
