    I Are there currently working colliders with unequal beam sizes?

    As a small remark: for electron storage rings the equilibrium emittance is determined by the radiative effects and scale as ##\epsilon_0 \propto \gamma^2##. So for two identical lattices the high-energy beam will have larger emittance.

    Physics Job prospects for accelerator physics

    Just to add to my last comment: If you're interested in working at the national laboratories around Europe, you can always check what kinds of positions they have open right now to get a feeling of the job prospects. Here is a (non-exhaustive) list of the larger laboratories (heavily light...

    Physics Job prospects for accelerator physics

    IBA makes medical cyclotrons in Belgium. As was mentioned above, a PhD is a requirement if you want to hold a research position. With e.g. an engineering degree you can work on components for accelerators such as RF cavities, magnets and vacuum components. If you want to do beam dynamics you...

    I What are the differences between Ion Linac and Electron Linac?

    It seems to me that you've got the basic right. I think a better and more accessible resource than those MIT handouts is the lecture notes from the major accelerator schools, e.g. the CERN Accelerator School (CAS) or the Joint Universities Accelerator School (JUAS). In [1,2] you have the...

    I Clarification of accelerator physics terminology

    Orbit bumps are modifications to the closed orbit by the use of corrector (steerer) magnets in a local part of the machine. Orbit bumps are typically either 2-, 3- or 4-corrector bumps: before the first corrector and after the last corrector, the orbit will be unchanged. 2-corrector bumps are...

    I Clarification of accelerator physics terminology

    This is again not really my area of expertise, and I'm not completely sure about the collider-jargon, but here are my two cents: When you have a stored beam of particles, you will always loose some particles. The "luminosity burn-off" is the loss of particles due to the Luminosity, i.e. the...

    Accelerating electrons and positrons

    Hi! You've already received the correct answers above, but I just wanted to correct the statement regarding the injection energy into colliders made by @ZapperZ above: For LEP, and most other high-energy colliders, the injected particles have a lower energy than the final energy. For LEP, the...

    I Clarification of accelerator physics terminology

    Some of the concepts of ion- (and proton-) machines aren't within my area of expertise, so unfortunately I cannot give you a whole lot of (qualified) help here. Please take my reply with a grain of salt and extra caution! ;-) An electron lens is a setup originally developed to compensate...

    I Clarification of accelerator physics terminology

    Glad I could help! The best list of acronyms for I could find online was from the LHC working group [1]. Note that these acronyms are CERN (and maybe even LHC) specific, meaning that the acronyms might differ at e.g. Fermilab, Brookhaven etc. One must probably be an LHC expert to know the...

    Computational projects in Accelerator Physics

    I can mostly speak for Accelerator Toolbox (AT), since that is the main tool for my own work. How it normally works is that one must first define a "lattice", which is the accelerator structure so to say. In AT, there is already implemented all the standard magnetic elements, so one defines...

    Computational projects in Accelerator Physics

    Hi, First of all, I think it would be good for you to get a better feeling of the field of accelerator physics. Since you aren't (as I understand) enrolled at a school with an accelerator program, I would recommend you to start looking into the basis of accelerator physics yourself. I interpret...

    I Clarification of accelerator physics terminology

    Hello! It seems that I’m a bit late, so you might already have found answers to your questions. Most (if not all) of your questions are addressed in during the lectures of the CERN Accelerator School (CAS), either the introductory [1] or the advanced [2] one. The lectures are generally easy to...
