Performance of aerogel as Cherenkov radiator [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2004
Abstract Aerogel with index of refraction around 1.03 has been studied as Cherenkov radiator in a test at CERN PS using a π− and a mixed π+/p beam of momenta between 6 and 10 GeV /c . The Cherenkov photons were detected by means of four large HPD tubes designed and constructed at CERN.

Transforming Cherenkov radiation in metamaterials [PDF]

SPIE Proceedings, 2015
In this contribution, we explore the generation of light in transformation-optical media. When charged particles move through a transformation-optical material with a speed larger than the phase velocity of light in the medium, Cherenkov light is emitted.

Transverse‐Electric Cherenkov Radiation for TeV‐Scale Particle Detection

Advanced Science, EarlyView.
Finite refractive indices of naturally existing materials place a fundamental ceiling on the momentum of detectable particles in traditional Cherenkov detectors. This work demonstrates transverse‐electric graphene plasmon Cherenkov radiation, breaking the momentum barrier for particle detection beyond the TeV scale with exceptional robustness and ...

Imaging radiation dose in breast radiotherapy by X-ray CT calibration of Cherenkov light

Nature Communications, 2020
Imaging Cherenkov emission during radiotherapy can provide information on the delivered radiation dose, but is attenuated by optical properties of the tissue.

Water‐Wave Pancharatnam‐Berry Phase Induced by 4D Spin‐Orbit State Evolution

Advanced Science, EarlyView.
The first observation of the Pancharatnam‐Berry (PB) phase in water waves is reported, revealing its extraordinary properties including unbounded phase values, spin‐momentum‐locked unidirectional channels, and a Poincaré hypersphere representation. These findings demonstrate the universality of the PB phase across different wave systems and in higher ...

Cherenkov radiation in a photon gas

New Journal of Physics, 2005
It is well-known that a charged particle moving with constant velocity in vacuum does not radiate. In a medium the situation can be different. If the so called Cherenkov condition is satisfied, i.e. the particle velocity exceeds the phase speed in the medium, the particle will radiate.

Bogoliubov-Cherenkov radiation in an atom laser [PDF]

Physical Review A, 2018
We develop a simple yet powerful technique to study Bogoliubov-Cherenkov radiation by producing a pulsed atom laser from a strongly confined Bose-Einstein condensate. Such radiation results when the atom laser pulse falls past a Bose-Einstein condensate at high-hypersonic speeds, modifying the spatial profile to display a characteristic twin jet ...
