A High Energy Proton-electron-positron Colliding Beam System*
A system of two intersecting storage rings of gross radius 260 m, one for protons and the other for electrons and positrons, is described. The maximum energy of the stored proton beam is 70 GeV, that of the electron and positron beams 15 GeV; so the center-of-mass energies are 65 GeV for e-p collisions and 30 GeV for e+ecollisions. The performance of the system is determined by the RF power ava...
متن کاملLONGITbDINAL EFFECTS OF COLLIDING BEAM SPACE CHARGE FORCES IN ELECTRON-POSITRON STORkE RINGS WITH CROSkNG ANGLES*
In electron-positron storage rings in which the orbits of the colliding beams cross at a substantial angle, a phase-dependent longitudinal force is exerted on the particles of each beam by the bunches of the other. The effects of this force on both incoherent and coherent longitudinal particle motion are investigated. These effects impose a limit on the number of particles which can be stored i...
متن کاملOptimization of Process Parameters of Electron Beam Welded Fe49Co2V Alloys
Electron beam welding has shown a remarkable job in the space industry for welding of components. It is performed under a vacuum environment that eliminates foreign matter such as hydrogen, oxygen, and other gases. Joining of similar and dissimilar materials is the main advantage of electron beam welding with high depth to width ratio as well as sharp focus at the point where parts are to be we...
متن کاملMeasurement of Colliding Beam Parameters with Wide Angle Beamstrahlung
where the N1,2 and σx,y,z are the beam populations and spatial dimensions at any given time t (which is a run-time variable of order one hour). This formula becomes rather complex over time. Particles are deflected by the other beam at each crossing, significantly affecting the Twiss matrix of the machine. The beam currents Ni(t) decrease due to beam lifetime also causing the machine’s Twiss ma...
متن کاملExperimental demonstration of colliding-beam-lifetime improvement by electron lenses.
We report the successful application of space-charge forces of a low-energy electron beam for improvement of particle lifetime determined by beam-beam interaction at a high-energy collider. In our experiments, an electron lens, a novel instrument developed for the beam-beam compensation, was set on a 980-GeV proton bunch at the Fermilab Tevatron proton-antiproton collider. The proton-bunch loss...
