Title: Preliminary Design of the Interaction Region Beam Transport Systems for JLEIC

Abstract

The Jefferson Lab Electron Ion Collider (JLEIC) is a proposed new machine for nuclear physics research. As proposed, it will deliver between 15 and 65 GeV center of mass energy collision between electrons and nuclei. It uses the existing CEBAF accelerator as a full energy injector to deliver 3 to 10 GeV electrons into a new electron collider ring. An all new ion accelerator and collider complex will deliver up to 100 GeV protons, or 40 GeV/nucleon ions. The machine will have luminosity goals above 10 33cm -2 sec -1 in the whole energy range with a maximum of a few 10 34 cm -2 sec-1. The two collider rings use a unique figure eight layout to deliver a high degree of polarization in both beams. The machine will include room for two interaction regions with only one initially installed. The crossing angle in the primary interaction region will be 50 mrad. The whole detector region including forward detection covers about 80 meters of the JLEIC complex. This paper will describe the requirements and preliminary designs for both the ion and electron beam transport systems in the most complex 32m region immediately around the interaction point. The beam transport systemmore » includes three separate cryostats housing over thirty-seven superconducting magnets operating at ~4.5K. Thus, the design of these cryostats must be closely integrated with the elements of the JLEIC detector.« less
