What is the difference between wigglers, bending magnets and undulators?

At storage ring of a synchrotron we have three systems: wigglers, bending magnets and undulators, which have influence on the electron flow. Could you answer, what exact difference between them in a ...

Does a superconductor spinning in a magnetic field radiate?

According to the cyclotron radiation formula: $$ \frac{dE}{dt} = - \frac{\sigma_t B^2 V^2}{c \mu_0 }$$ charges will radiate even when moving perpendicular to the magnetic field (which presumably ...

Kinetic energy of an electron in synchrotron

The question states as follows: An electron is accelerated in a LINAC (LINear Accelerator) so that it's kinetic energy is 1.00 GeV. Then it is transferred to a synchrotron where it's energy (didn't ...

Do atoms produce synchrotron radiation?

Since synchrotron radiation is created when charged particles are radially accelerated and electrons are definitely orbiting a nucleus (assuming a Bohr model), electron should then logically emit ...

Is “microbunching” in a free electron laser limited by the Pauli exclusion principle?

As I understand it, a free electron laser can basically be pictured as a synchrotron light source with an undulator which by the particular setup causes the electrons to self-attune so that they ...

What's the difference between cyclotron radiation and synchrotron radiation?

What's the difference between cyclotron radiation and synchrotron radiation? The title says it. If there is a difference between a cyclotron and a synchrotron beyond the particles being accelerated in ...

Electron energy in a synchrotron storage ring vs. X-ray energy from the wiggler: why is the latter much lower?

I know in large synchrotron facilities some beamlines produce very intense X-rays by injecting the accelerated electrons into "wigglers". I have read that the typical energy of the electrons in the ...

Do particle accelerators produce (dangerous) radiation?

I was under the impression that particle accelerators were pretty harmless, but some article said that they produce harmful radiation when you're in the tunnel. Given that the Internet... isn't always ...

Free Electron Lasers (FEL) and limits on laser wavelength

Free Electron Lasers are based on Synchroton coherent radiation when a collimated electron beam suffers trajectory curvature due to a strong bouncing magnetic field inside an undulator. Free Electron ...

Is synchrotron radiation considered incandescent?

Synchrotron radiation is produced via the acceleration of charged particles, much like incandescence. However, all information I've seen state that incandescent light is produced exclusively from the ...

The Synchrotron at CalTech

In the Feynman Lectures Vol. 1, it says that the Synchrotron at the California Institute of Technology is capable of producing electromagnetic Radiations with a frequency of $10^{24}$ cycles per ...

How do I rearrange dE/dt to find an electron's 'half-life' due to synchrotron radiation?

I know that $-\frac{\mathrm{d}E}{\mathrm{d}t} \propto E^2$ for an electron losing energy to synchrotron radiation, but I can't find how to arrange this to give the time it would take for the electron ...

Does bunching reduce synchrotron radiation?

A continuous charge distribution flowing as a constant current in a closed loop doesn't radiate. Is it therefore true that as you increase the number of proton bunches in the LHC, while keeping the ...

Converting between brilliance, intensity, and flux

This one should be a bit of a softball, but I can't find it explicitly stated anywhere on the internet, and my basic unit analysis doesn't seem to work. Suppose you have a beam of synchrotron ...
