Accelerator and Beams - Tools for Discovery and Innovation

SUMMARY

The discussion centers on the misconceptions surrounding particle accelerators, particularly the distinction between particle accelerators and particle colliders in high energy physics. The American Physical Society (APS) has published a brochure clarifying that the majority of particle accelerator applications extend beyond high energy physics. Key resources mentioned include the brochure from APS, an article by Michael Turner, and a downloadable book titled "Principles of Charged Particle Acceleration" by Stanley Humphries. The conversation also touches on synchrotron radiation and its relationship to kinetic energy and magnetic forces.

PREREQUISITES
  • Understanding of particle accelerators and their applications
  • Familiarity with synchrotron radiation and its effects
  • Knowledge of classical electromagnetism, particularly Lorentz force
  • Basic principles of kinetic energy in particle physics
NEXT STEPS
  • Read the APS brochure on particle accelerators
  • Study Michael Turner's article on particle accelerator applications
  • Download and review "Principles of Charged Particle Acceleration" by Stanley Humphries
  • Research the mechanics of synchrotron radiation and its energy implications
USEFUL FOR

Physicists, engineers, and students interested in particle physics, particularly those exploring the applications and principles of particle accelerators and synchrotron radiation.

The Division of Physics of Beams of the American Physical Society (APS) has produced this wonderful brochure titled "http://www.aps.org/units/dpb/upload/brochure.pdf" ". It essentially describe what a particle accelerator is, and more importantly, what it is used for.

The main purpose here is to eliminate the wrong myth that "particle accelerator" automatically means "particle collider" in high energy physics. Nothing could be further than the truth, and hopefully, someone reading this brochure will get the idea that the MAJORITY of the application for a particle accelerator has NOTHING to do with high energy physics.

A supplement for this brochure is a useful article written a while back by Michael Turner titled "http://scitation.aip.org/journals/doc/PHTOAD-ft/vol_56/iss_9/10_1.shtml" ", that essentially tried to convey the same message.

Thanks for the link, it looks like good read. i just started reading the introduction and on page 3 Humphries states that " magnetic forces cannot affect a particles kinetic energy".
1 question.
Do the photons of synchrotron radiation not carry away/convert the kinetic energy of the particle?

You are correct in that sunchrotron radiation is a direct consequence of the F = q(v x B) (Lorentz) force. I think the author was trying to say is that since both B and F are orthogonal to v, no work is being done, and the force does not add to or subtract from the velocity.

thx for reply Bob, where does the energy come from for synchrotron radiation... is there a change in mass of the charged particle, or is the amount of energy needed for S.R. equal to the magnetic energy/force applied to the particle.

The synchrotron radiation comes from the deflection of positrons or electrons in bending magnets. it orthogonal to the velocity in the center of mass coord system, but is very forward radiation in the lab system, and comes from the particles' kinetic energy, which is replaced by RF cavities. I have seen potted copper coils on magnets turn black and crack by synchrotron radiation damage.

Er... you should be very careful here not to use "E=mc^2" in this process. This is simply classical E&M. The electron (or electron bunch) is losing kinetic energy in such a process.

How about E2= (pc)2+ (m0c2)2 ?
