Paper Abstract

Electron cooling of electron (and positron) sources may be important for future linear collider applications. Electron cooling works by superimposing a cooling electron beam on a hot particle beam. Heat is transferred from the hot beam to the cooling electron beam until thermal equilibrium is reached. The cooling electron beam is continuously generated and discarded into a collector, allowing the minimum beam temperature to be obtained. In order to cool electrons with electrons, an intermediary positron beam must be employed, since it is impossible to merge two beams of identical particles into the cooling straight. By adjusting the beta functions of the electron and positron lattices appropriately the final emittance of the stored electron beam can be made less than the emittance of the cooling electron beam. This paper will discuss accelerator physics issues relating to an electron cooled electron beam source.
