Linac-Lhc Ep Collider Options

Abstract

We describe various parameter scenarios for a linac-ring ep collider based on LHC and an independent electron linac. Luminosities between 1031 and 1033 cm-2s-1 can be achieved with a s.c. linac, operated either pulsed or in cw mode with optional recirculation, at a total electric wallplug power of order 20MW. Higher luminosities of several 1033 cm-2s-1 can be reached by investing more electric power or by energy recovery. Finally, merits of a linac-ring ep collider are discussed.
