### Do lasers with optical isolator or synchrotron radiation sources allow for Rabi cycles?

In Rabi cycle two-level system cyclically transitions between ground and excited state - bringing question where their energy difference goes during these transitions? For transition from ground to ...

### Minimum size of a synchrotron required to get desired wavelength?

Synchrotrons are regularly used to generate various wavelengths of light. I get that there is a tradeoff between electron energy and bending radius/angle required to obtain a given wl. (For example, ...

### How can one make a visible light bulb that works through cyclotron radiation?

I figure that I first start with a charged particle accelerator. Let's say we can make this from electromagnets arranged in a circular ring in the XY plane with a magnetic field $B$, perpendicular to ...

### Synchrotron radiation calculation details and expressing the flux

In chapter 14 of Jackson the energy radiated per unit frequency interval per unit solid angle is given: Integration over the angles gives: Finally, dividing by $\hbar \omega$ equation (14.91) gives ...

### When doesn't an accelerating charge emit light?

An accelerating electron or proton emits light via synchrotron radiation, but an accelerating ring of charge does not and Larmor suggests that a standing wave of charge wouldn't either {1}. Are there ...

### Could you use a synchrotron particle accelerator in a descending spiral pattern to create ion thrust for space travel?

Would it be theoretically possible to use a synchrotron particle accelerator that utilizes a spiral pattern to create ion thrust for space travel? In this scenario, ions would be accelerated in a ...

### Synchrotron Emission: Physical Intuition for the Broad Spectrum

I understand what is happening to the electron to have it emit synchrotron light. However, I am not physically understanding the reason that a pulse of light that an observer sees will be made up of ...

### Production of Light by Acceleration of Charged Particles

I'm reading the Willmott's book titled "An introduction to synchrotron radiation". At pg 55 it is stated: "The electric-field lines of a charged particle at rest or in uniform motion ...

### In a synchrotron, do the charged particles within the beam lose mass (or another type of energy) after radiation has been produced?

I've been researching accelerators and synchrotrons and am a bit confused on what happens to the particles within the storage ring once radiation has been produced. Do they keep circling the ring, do ...

### Effective Lorentz Factor in Cold Plasma, Razin Effect

I was studying about the synchrotron radiation in plasma medium and got stuck at a point. Usually the Lorentz factor is defined in the following way $$\gamma = \frac{1}{\sqrt{1-\frac{v^2}{c^2}}}$$ ...

### What is the field responsible for the synchrotron emission?

Consider a usual synchrotron emission electron. What is the field responsible for its emission? I know, for example, that the magnetic field that we have in the problem is not because magnetic fields ...

### The mechanism behind the Lorentz force [duplicate]

It has been known for 130 years that a moving electron entering an external magnetic field is deflected (Lorentz force, Hall effects, synchrotrons). What I have never read is a description of how this ...

### Physical interpretation of relativistic synchrotron radiation

When an electron approaches the speed of light, the emission pattern is sharply collimated forward, in the direction of motion. I can see how this is mathematically true from taking the relativistic ...

### Is Inelastic Neutron Scattering (INS) any good compared to synchrotron IXS for determining phonon dispersion relations?

Both INS and IXS can be used to study phonon dispersion relations. While INS requires large sample size due to low inelastic scattering cross section, IXS using synchrotron x-ray sources do not ...

### Bremsstrahlung in synchrotrons

In synchrotons electrons are accelerated by undulators or wigglers. However, I don't get how you produce Bremsstrahlung, because Bremsstrahlung is a 3-particle process: charged particles, ions and ...

### What is the difference between an undulator and a free-electron laser (FEL)?

I am very confused by the graphic below: In particular, why are undulators and FEL separated? Furthermore, I do not quite understand how the intensity values come to be: Wiggler: Every electron ...

### Why is the opening angle of synchrotron radiation less than $1/\gamma$?

I am currently studying free-electron laser which accelerate electrons and use undulators to create synchrotron radiation. In a variety of graphics and diagrams I see an opening angle of $\pm 1/\gamma$...

### Are Bremsstrahlung and the Unruh effect equivalent?

This paper argues that the absorption and emission rates from and to the thermal Unruh bath of a proton viewed in a coaccelerated frame is equal to the emission rated viewed from an inertial observer. ...

### Origin of the energy distribution of synchrotron radiation

Is there an easy explanation why synchrotron radiation from a bending magnet (e.g. in an electron storage ring) has an energy distribution? In other words, given a specific magnet with a defined ...
