JLEIC Collaboration Meeting Spring 2019

US/Eastern
Description
A high energy high luminosity polarized electron-ion collider was identified and recommended by the US DOE/NSF Nuclear Science Advisory Committee (NSAC) as the next major US nuclear science research facility in its 2015 Long Range Plan (LRP). JLEIC, an electron-ion collider based on the CEBAF recirculating Superconducting RF linac, has been proposed at Jefferson Lab for responding to this NSAC-LRP recommendation an as the lab's future nuclear science program beyond 12 GeV CEBAF fixed target program. The design studies and accelerator R&D of JLEIC have been actively pursued over the last ten years by Jefferson Lab staff and external collaborators.
