Plasma physics at the final focus of high‐energy colliders

摘要: The plasma physics associated with intense electron and positron beams in high‐energy colliders is discussed. focusing oscillation of these are studied the presence an externally supplied (a lens) self‐consistent fields interpenetrating beams. A lens can provide strong a beam by shielding beam’s radial space‐charge electric field allowing it to self‐pinch its self‐generated azimuthal magnetic field. force be equivalent quadrupole magnet strengths order hundreds MG/cm. Theoretical computational work characterizing aberrations final spot sizes possible lenses presented. Furthermore, when e+ e− overlap at interaction point (i.e., collide), they behave (temporarily) as two‐component plasma. self‐pinching or disruption one another e+e− modeled analytically two‐dimensional particle‐in‐cel...
