Questions tagged [accelerator-physics]
is appropriate for questions dealing with the physics of beams in accelerators (synchrotrons, cyclotrons, linacs, betatrons and other types of accelerators); the ways in which beams are generated; the accelerating, bending and focusing equipment; and the intrinsic limits that arise in trying to manipulate beams. DO NOT USE THIS TAG for questions that concern the use of the particle beams once they arrive in the experimental hall.

Highly relativistic electron scattering in thin plasma
I am curious about how extremely relativistic electrons (10s of GeVs to single TeVs) scatter when going through the interplanetary and interstellar medium, which is a thin plasma. I have read about ...

Going from a photon flux to a photon flux after a slit (partial photon flux)
Thanks to the help of someone here and others a few weeks ago (who referred me to the Jackson), I have managed to express the flux of a bending magnet like so:
$\frac{d_N}{\frac{d\omega}{\omega}} = \...

Expressing synchrotron radiation, bending magnet flux
In chapter 14 of Jackson the number of photons per unit frequency interval is given by:
How can I go from $\frac{photons}{d \omega}$ to a flux expressed in photons per second per 0.1% bandwith $\frac{...

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 ...

Bending angle equation of particle in a magnetic and electric field
Using the equations for an Electric field and Magnetic field between two plates:
$$
E = \frac Vr
$$
$$
B=\frac{2I}{2\pi r}\cdot\mu_0
$$
where $V$ is plate voltage, $r$ is plate separation, $I$ is ...

Particle acceleration - why are colliders seemingly so limited?
I imagine this has been asked before but I am wondering why particle accelerators are so limited.
- Why do they have to be big circles? Is there no other technique of accelerating charged particles?

Efficiency of particle accelerators
Say the SLAC linear accelerator, to perform inelastic scattering, wants to fire an electron accelerated to 0.99c the speed of light at targets of atomic nuclei.
After the collision, the resulting ...

As the speed time graph for a body thrown vertically upwards is not differentiable at the top point so why acc. is taken as 9.8 m/s² at the top point?
In the shown speed - time graph for a body thrown vertically up there is a sharp kink in the graph at the instant for which body is at highest position ie not differentiable so we can't find ...
