“…Providing cooling at even higher energies would be easier with RF acceleration of electron beam, and thus using bunched electron beam for cooling. Significant efforts were devoted to explore various aspects of such bunched electron beam cooling as part of R&D of high-energy electron cooling for RHIC [2,3]. However, experimental studies of such cooling are still lacking.…”

“…R&D ERL, shown in Fig.1, will serve as a test-bed for future RHIC projects -RHIC II with ERL-based electron cooling [1,2] and 10-to-20 GeV ERL for lepton-ion collider eRHIC [3,4]. It will also address more general issues expanding capabilities of ERLS: from novel SRF injectors [5], high current and high brightness beam ERL operation [6] and highly flexibility lattice [7,8] to enable covering a vast operational parameter space from nonachromatic lattice to achromatic large range tunability of of R 12 , R 34 and R 56 parameters.…”

In this paper we present status and plans for the 20-MeV R&D energy recovery linac (ERL), which is under construction at Collider Accelerator Department at BNL. The facility is based on high current (up to 0.5 A of average current) super-conducting 2.5 MeV RF gun, single-mode super-conducting 5-cell RF linac and about 20-m long return loop with very flexible lattice. The R&D ERL, which is planned for commissioning in early 2009, aims to address many outstanding questions relevant for high current, high brightness energy-recovery linacs. Figure 1: Layout of R&D ERL in Bldg. 912 at Collider-Accelerator Department, BNL: 1 -R&D ERL control room; 2 -diagnostic and control racks; 3 -703.75 MHz, 50 kW CW RF transmitter; 4 -703.75 MHz, 1 MW CW klystron; 5-2 MW CW HV power supply for the klystron; 6 -power supplies and other electronics; 7 -shielded R&D ERL vault with removed roof beams; 8 -2 MeV, 703.75 MHz SRF photo-injector; 9 -20 MeV, 703.75 MHz 5-cell SRF linac; 10 -return loop; 11 -beam dump; 12-part of the 1.8 K o cryogenic system (most of the system is outside the picture).

“…The electron cooler for the proposed luminosity upgrade of RHIC [4,13] represents a significant design challenge due to the high energy of the ion beam. While lower energy ion beams can be cooled by continuous electron beams, the 55 MeV electron beam needed by RHIC must be a bunched beam, with consequently higher temperature electrons.…”
