What is Accelerator physics: Definition and 22 Discussions

Accelerator physics is a branch of applied physics, concerned with designing, building and operating particle accelerators. As such, it can be described as the study of motion, manipulation and observation of relativistic charged particle beams and their interaction with accelerator structures by electromagnetic fields.
It is also related to other fields:

Microwave engineering (for acceleration/deflection structures in the radio frequency range).
Optics with an emphasis on geometrical optics (beam focusing and bending) and laser physics (laser-particle interaction).
Computer technology with an emphasis on digital signal processing; e.g., for automated manipulation of the particle beam.The experiments conducted with particle accelerators are not regarded as part of accelerator physics, but belong (according to the objectives of the experiments) to, e.g., particle physics, nuclear physics, condensed matter physics or materials physics. The types of experiments done at a particular accelerator facility are determined by characteristics of the generated particle beam such as average energy, particle type, intensity, and dimensions.

    I About Direct Laser Acceleration

    How does this Lawson–Woodward theorem work. I read on the wiki that the particles cannot be accelerated by lasers. But I do see acceleration of electrons with free space. I wonder how this is done. https://rdcu.be/c0fRw http://dx.doi.org/10.1103/PhysRevAccelBeams.19.021303 In addition, I have...

    B Gamma rays over very large areas

    According to this link https://apps.dtic.mil/dtic/tr/fulltext/u2/a351472.pdf, HERMES III at Sandia National Labs can generate very large area gamma rays by converting the electron beam into bremsstrahlung radiations after hitting the tantalum target. As we can see in the isodose contours in the...

    Question about accelerator physics

    In accelerator physics, mapping matrix is often used to describe particle's motion.For a given one turn mapping matrix,namely M(s+L|s) ,and initial (x,x').After matrix multiplication, I find the value of (x,x') changes which means particle's position and angle changes at the same s after one...
