Propagation of charged particle inside a set of magnets

Click For Summary

Discussion Overview

The discussion centers around the equations governing the motion of charged particles within a configuration of dipole and quadrupole magnets, particularly in the context of simulating a particle beam passing through these magnetic fields. Participants express interest in both classical relations and more complex parameters such as momentum components and exit angles.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant seeks equations for simulating a charged particle's trajectory in a dipole-quadrupole-dipole arrangement, emphasizing the need for more than just basic calculations.
  • Another participant suggests a specific reference, "The Optics of Charged Particle Beams," as a potential resource.
  • There is a request for more recent literature, indicating a concern about the relevance of older texts.
  • One participant questions whether the fundamental laws of physics have changed, implying that older references might still be valid.
  • A suggestion is made to use "beam optics" as a keyword for further research.
  • Another participant expresses frustration about the limitations of their library's resources, indicating a desire for alternative suggestions.
  • There is a mention of reluctance to engage in guessing which books might be available in libraries, highlighting a challenge in accessing relevant literature.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the availability of recent literature or the necessity of newer references, indicating a mix of perspectives on the relevance of older texts versus the need for updated resources.

Contextual Notes

Limitations include the lack of specific equations or derivations requested by the original poster, as well as the uncertainty regarding the availability of literature in participants' libraries.

Hi

I am trying to find the equations of a charged particle inside a dipole & quadripole. Practically, I need to write a simulation program for it which assumes a beam passing through a dipole-quadripole-dipole which are setting around an arc. Is there some recommended literature ? Of course, I am not just interested into the classical relation of calculating the radius of the bended particle, rather than the px,py, exiting_angle etc-. For instance, I found in some outdated code, that costheta = q/sqrt(px*px+1) but could not find how to derive this formula.

Any help/tips appreciated.

Regards

something more recent? my library does not have it...
 
More recent? Do you think the laws of physics have changed in the last few years?
 
Probably you missed that my library does not have it..so any other book suggestion ?
 
No, I just didn't want to play the game of "guess which books my library has".
