### Energy loss due to Cherenkov radiation

I'm trying to find a formula for (or some sort of direction towards approximating) the energy lost by a ultra relativistic positron when traveling through a cherenkov detector but I can't seem to find ...

### Speed in a medium

Let's say, that there is medium, where the speed of light is $10^8 \, \rm m/s$. So in that medium if there exists a particle that is moving through without any hindrance what would be the speed limit ...

### Amaterasu particle's secondary particles travel faster than the speed of light?

From this article in The Guardian When ultra-high-energy cosmic rays hit Earth’s atmosphere, they initiate a cascade of secondary particles and electromagnetic radiation in what is known as an ...

### Is the speed of causality slower in water?

I've recently read that what most people learned to think of as the 'speed of light' is actually the 'speed of causality', and that light just happens to travel at that speed (through free-space.) I'...

It is explained that Cherenkov radiation is light that emit a particle inside a refractive material when the speed of the emitted light is slower than $c$. So my hypothetical question is what would be ...

### Cherenkov radiation in glass via electron tube?

Recently I was experimenting with an vacuum tube attached to a wimshurst machine and measuring the X-Rays emissions. While doing so, I noticed the the surface of the tube began to glow blue in some ...

### Cherenkov light and refractive index

LHCb’s Ring Imaging CHerenkov detector (RICH) is aimed at telling different charged particles apart by measuring their velocity, which, together with an independent measurement of their momentum, is ...

### Minimal frequency for Cherenkov radiation

I'm trying to figure out the possible range of frequencies of the photons emitted in the Cherenkov effect, and came across something strange: If I assume that the emitting electron's initial energy ...

### What is Cherenkov radiation? [duplicate]

What is Cherenkov radiation? I came across this concept when I was learning SR. Why can't particles moving at speed of excess of speed of light in the medium. Why it does not violate the limitation ...

### Why only charged particles can emit Cherenkov in glass (and Neutrinos themselves not)

I have read this: https://en.wikipedia.org/wiki/Cherenkov_radiation https://en.wikipedia.org/wiki/Measurements_of_neutrino_speed https://en.wikipedia.org/wiki/Neutrino We know that neutrinos ...

### Do massless particles create tiny gravity-booms?

So just a precursor, my main focus is math and I don't fully understand everything in physics so I apologize if this has an obvious answer or the wrong tags are used. That being said, I do know that ...

### Is it possible to create anti-muons in a particle accelerator?

I love particle and nuclear physics and I'm starting to search some things about it even. So, my doubt is: is it possible to create antimuons (positive charged muons) in a particle accelerator, but ...

### Trouble with Classical Derivation of Cherenkov Radiation Mechanism -- Magnetic Field Intensity

I've been going through a translation of Frank and Tamm's original theory on Cherenkov radiation published by Jelley in 1958, and the bottom line is that I'm stuck on one of the intuitive leaps that ...

### Cherenkov radiation in non-water solvents

Will we see or can we measure Cherenkov radiation in media different from pure water? It is well known that Cherenkov radiation is observable by bare eye in nuclear pools. But if we replace water ...

### Faster than light in a medium [duplicate]

It is a remarkable well-stablished fact that the light velocity in vacuum, $c \simeq 3.10^8 m/s$ is the upper limit for the velocity of ordinary matter, never to be achieved. It is also well-...

### How is the energy of a particle measured in a Cherenkov detector [closed]

I don't understand how is the energy measured in a cherenkov detector. How is the number of photons radiated related to the energy of the particle or the measure of energy has nothing to do with the ...

### Can a particle be identified when one knows $\left<dE/dx\right>$ and the Cherenkov angle $\theta_c$?

I have a question about if it would be possible to identify a particle by measuring the energy loss due to ionization $\langle dE/dx\rangle$ and the Cherenkov angle $\theta_c$. I assume that we know ...

Cherenkov radiation is electromagnetic radiation emitted when a charged particle passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. Neutrons are ...

### Which has better reflective properties? Aluminum oxide or Titanium dioxide?

I know TiO2 reflects better than Al2O3 but I can't understand why, in most radiation detection applications using scintillation, aluminum oxide is used as a reflective coating more than titanium ...
