Cornell University has prototyped technology essential for any high-brightness electron ERL. This includes a DC gun and an SRF injector Linac, a high-current CW cryomodule, a high-power beam stop, and several diagnostics tools for high-current and high-brightness beams. All these are now available to equip a one-cryomodule ERL, and laboratory space has been cleared out and is radiation shielded to install this ERL at Cornell. BNL has designed a multi-turn ERL for eRHIC where beam is transported 22 times around the RHIC tunnel. The number of transport lines is minimized by using two non-scaling FFAG arcs. A collaboration between BNL and Cornell has been formed to investigate the new NS-FFAG optics of this design, built with permanent magnets, and to commission the unprecedented multi-turn ERL operation. This collaboration plans to install a NS-FFAG return loop and the associated optics-matching sections at Cornell’s one-cryomodule ERL. This FFAG-ERL will be installed in several stages, each of which investigates crutial parts of this new design.

The Low-energy RHIC electron Cooler (LEReC) system has been approved to be build at the Brookhaven National Laboratory. The electron cooling system will be able to deliver an electron beam of adequate quality in a wide range of electron beam energies (1.6-5 MeV). While existing electron coolers use a DC electron beam this will be the first application of using a bunched electron beam provided by an ERL, paving the way for future electron coolers at higher energies.
