A Low Emittance, Flat-beam Electron Source for Linear Colliders
We present a method to generate a flat (large horizontal to vertical emittance ratio) electron beam suitable for Linear Colliders. The concept is based on a round-beam rf-laser gun with finite solenoid field at the cathode together with a special beam optics adapter. Computer simulations of this new type of beam source show that the beam quality required for a Linear Collider may be obtainable ...
متن کاملLaser cooling of electron beams at linear colliders . ∗
A method of electron beam cooling is considered which can be used for linear colliders. The electron beam is cooled during collision with focused powerful laser pulse. The ultimate transverse emittances are much below those achievable by other methods. This method is especially useful for high energy gamma-gamma colliders. In this paper we review and analyse limitations in this method, also dis...
متن کاملA Perspective on Lepton-photon Physics
WOLFGANG K. H. PANOFSKY Stanford Linear Accelerator Center Stanford University, Stanford, California 94309 ABSTRACT This paper reviews some key experiment,s of the past in which the same basic physical processes are attacked both through lepton-photon interactions and by using hadron machines as primary tools. Not surprisingly, it is conrludeh that the basic distinction between lepion-photon ph...
متن کاملGamma - Gamma , Gamma - Electron Colliders ∗
It is very likely that in 3-4 years the construction of one or two linear colliders with c.m.s energy up to 0.5–1.5 TeV will be started. Besides eecollisions, linear colliders give a unique possibility to study γγ and γe interactions at energies and luminosities comparable to those in ee collisions. High energy photons for γγ and γe collisions can be obtained using laser backscattering. These t...
متن کاملAlternative Positron-Target Design for Electron-Positron Colliders*
Current electron-positron linear colliders are limited in luminosity by the number of positrons which can be generated from targets presently used. This paper examines the possibility of using an alternate wire-target geometry for the production of positrons via an electron-induced electromagnetic cascade shower.
