What would happen if the electric field was cut to a cyclotron half-way?
After accelerating say a proton, half way, if the alternating electric field was cut, would the proton maintain a perpetual circular motion at the same radius? I know that any charged particle moving...
View ArticleHow does a synchroton work?
I know that a linear accelerator (linac) works by having terminals that get longer progressively and changes polarity due to AC current. And I also know that a cyclotron works by having two...
View ArticleWhy doesn't the LHC accelerate electrons?
Electrons have a much bigger charge density as the protons (and especially lead nuclei), aren’t compound particles as the protons (and especially lead nuclei) are able to get a much bigger energy with...
View ArticleIs “microbunching” in a free electron laser limited by the Pauli exclusion...
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...

When beam (bunch of electrons) transverse RF cavity, it will excite modes (resonant frequencies). The mode for steady state is quite well described, I am wondering is there any theory describe the...

Using ion beam to create strong magnetic field
Consider, I want to make very strong magnetic field in some spot in space ( focus ) but I cannot put any solid material ( like metal conductor, or superconductor ) close to that spot (e.g. because...
View ArticleElectron beam in magnetic field – increase or decrease the field?
When I fire an electron beam into homogenous magnetic field ( eg. inside Helmholtz coil ) it will bend into a circle => it will form a coil ( = current loop ) itself. The magnetic field created by...
View ArticleHow would the CLIC accelerator work?
After reading what I could find about the CLIC accelerator, I still don’t understand how it would work. If someone could explain how the CLIC would work, I would greatly appreciate it.

LinAc standing wave
I have a question regarding Linear Accelerators (Linacs): Originally, traveling HF waves were used to accelerate electrons inside a Linac. You can see a sketch in the following picture. The further the...
View ArticleWhy do positron generators use solenoid magnets to focus positrons instead of...
When positrons are generated from a particle beam hitting a dense target, why do we use solenoid electromagnets to focus the resulting positrons? As far as I can see, a FODO (focus-open-defocus-open,...
