 
Abstract
The LHeC project aims to supplement the CERN machine infrastructure with a      
(nominally 60 GeV) electron accelerator, producing electron-proton              
collisions at an instantaneous luminosity of order 10^33 cm^-2 s^-1             
simultaneously with the existing LHC proton-proton collisions. An               
electron-ion programme is also foreseen. This seminar will focus mainly on      
the physics potential of an LHeC with this specification and will also          
briefly cover accelerator and detector aspects.
