Accelerator Physics: Questions from a Physicist

Click For Summary

Discussion Overview

The discussion revolves around the field of accelerator physics (AP), exploring its accessibility for physicists with backgrounds in materials science and other disciplines. Participants inquire about the difficulty of working in AP, the relevance of programming skills, job opportunities, and the relationship between accelerator physics and particle physics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Career-related

Main Points Raised

  • One participant questions the difficulty of entering accelerator physics for someone with a materials science background and asks about the necessary programming experience.
  • Another participant suggests that a PhD is likely required for postdoc positions and notes that a background in particle or nuclear physics may facilitate entry into the field.
  • It is mentioned that accelerator physics heavily relies on classical electromagnetism and differential equations, with references to specific textbooks like Jackson's.
  • Programming skills are deemed important, particularly for using various codes related to beam dynamics and electromagnetic field solutions.
  • Some participants express interest in specific aspects of accelerator physics, such as synchrotrons and vacuum systems, while noting their lack of experience in particle physics.
  • There is a claim that accelerator physics is distinct from particle physics, with one participant emphasizing that accelerator physics can also apply to medical facilities and does not solely pertain to high-energy physics experiments.
  • Resources such as the USPAS are mentioned as valuable for gaining knowledge in accelerator physics, with courses available for both students and professionals transitioning into the field.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between accelerator physics and particle physics, with some asserting that they are distinct fields while others acknowledge their intersection. The discussion remains unresolved regarding the exact nature of this relationship and the implications for entering the field.

Contextual Notes

Some participants highlight the need for specific programming skills and knowledge of certain codes, but there is no consensus on the exact requirements for entering the field or the nature of job opportunities available.

Hello all,
for a normal physicist (a bit with materials science) how easy will be accelerator physics (AP). Is AP is that difficult to work with ?
Is AP is purely applying theory to beam physics ?
How much programming experience needed ?
Is it easy to get a job/postdoc in accelerator physics area for a normal physicist?

It will be highly helpful for me. If anyone working in AP area please discuss.
[these days i see lots of accelerator physics jobs..]-is this area has lots of demand?

thanks a lot

Judging by your question I'm guessing you have a PhD (since you asked about postdocs). They are out there (look at the major accelerator facilities like SLAC, Fermi, CERN, DESY, etc).

AP is a lot of applying what you know about fundamental physics (think a combination of E&M and Mechanics with differential equations to your hearts content).

A background in particle or nuclear physics would probably be an easy step. A number of the people I work with did their PhD work in plasma physics and even electrical engineering.

As to programming experience it certainly helps. Being able to build computer models is of great utility.

Hope that helped.(If you're wondering I'm an accelerator operator with a BS on the way to a MS)
 
Accelerator physics involves predominantly classical E&M. This is where if you think the Jackson's textbook is mainly used as a torture device to graduate students, you will have to change your mind. You literally will need the book. You will need it in understanding the design of RF cavities, accelerating structure, and beam dynamics. This is also why electrical engineers are also common within this field of study.

You will need to know programming, especially if you are in beam physics. But you need to know it for your ability to use the various codes that are commonly used. Codes like PAMELA, PICT, etc, for beam dynamics, and more commercial packages such as COMSOL, Microwave Studio, etc. for EM field solution are quite common.

Most students who major in accelerator physics WILL enroll in one or more particle accelerator schools that are offered throughout the US, Europe, and Asia. Since no one school is able to offer all the necessary coursework for such a major, the particle accelerator community throughout the world has decided to offer college-credit courses for students. But these courses are also taken by professionals and people who already have degrees in other fields but are switching into accelerator physics. So the accelerator schools are quite useful.

Hi Both of you,

AP seems like a classical electrodynamics [as you mentioned JD Jackson's book]. Also like pure theory. But stuffs like syncrotron, beam physics, vacuum system in syncrotrons, are interesting for me. As i am not a particle physicist, i don't know how can i enter in these challenging areas.
Programming: I am ultra good..but average level programmer (only C).
PhD-not yet finished but in last stage of writing work..after writing i will apply..
Recently i notice few jobs (postdoc) in Fermilab..but all are particle physics, beam physics, AP, etc..But preference will be given to those who will take the 1st long-term postdoc.
let me see.
thanks, rajini

Accelerator physics has NOTHING to do with particle physics. That is a myth and a misunderstanding. A synchrotron light source isn't a "high energy physics" facility!

Now, accelerator physics DO work at collider facilities. This is because in that case, they are producing beams for high energy physics experiments. But accelerator physicists also work at medical accelerator facility that has nothing to do whatsoever with high energy/particle physics!

Look at the curriculum given in the link I gave to the USPAS. Do you see any "particle physics" class?

Zapper is spot on. Don't confuse the two subjects, they intersect but are certainly not the same.

If you want a better idea the texts by S. Y. Lee and Helmut Wiedemann are pretty comprehensive and are worth a look.
