Proton-ring and Electron-linac Collider (PRELC) as a (first) TeV-rangeelectron-proton or photon-proton collider

Abstract

The use of the existing proton storage rings combined with electron linear accelerator as a ring-linac type electron-proton or photon-proton collider is investigated. The total CM-energy of Proton-ring and Electron-linac Collider (PRELC) is in the range of 1.0 TeV. The most important physical issues are listed and the most critical machine aspects of the PRELC are studied. It is shown that the luminosities in the range of $10^{31}$ to $10^{32}$ could be achieved. The PRELC could be used simultaneously with the $e^+e^-$-collider if the refocused electron beam could be used as the electron beam for the PRELC.
