We con­sid­er three dif­fer­ent sce­nar­ios for the re­cir­cu­lat­ing elec­tron lin­ear ac­cel­er­a­tor (RLA) of a linac-ring type elec­tron-pro­ton col­lid­er based on the LHC (LHeC): i) a basic ver­sion con­sist­ing of a 60 GeV pulsed, 1.5 km long linac, ii) a high­er lu­mi­nos­i­ty con­fig­u­ra­tion with a 60 GeV 4 km long cw en­er­gy-re­cov­ery linac (ERL), and iii) a high en­er­gy op­tion using a 140 GeV pulsed linac of 4 km ac­tive length. This paper de­scribes the foot­print, op­tics of linac and re­turn arcs, emit­tance growth from chro­matic­i­ty and syn­chrotron ra­di­a­tion, a set of pa­ram­e­ters, and the per­for­mance reach for the three sce­nar­ios.

We re­port on the anal­y­sis of data col­lect­ed in the MERIT ex­per­i­ment at CERN dur­ing the Fall of 2007. These re­sults val­i­date the con­cept of a free mer­cury jet in­side a high-field solenoid mag­net as a tar­get for a pulsed pro­ton beam of 4-MW power, as need­ed for a fu­ture Muon Col­lid­er and/or Neu­tri­no Fac­to­ry.
