High-brightness electron beams for linac-based bunched beam electron cooling

Abstract: A high-current high-brightness electron accelerator for low-energy RHIC electron cooling (LEReC) was successfully commissioned at Brookhaven National Laboratory. The LEReC accelerator includes a dc photoemission gun, a laser system, a photocathode delivery system, magnets, beam diagnostics, a superconducting rf booster cavity, and a set of normal conducting rf cavities to provide enough flexibility to tune the beam in the longitudinal phase space. Cooling with nonmagnetized rf accelerated electron beams requir… Show more

“…RHIC physics searches for a critical point in the nuclear matter phase diagram [343] required operation below the nominal injection energy of 10 GeV/u. In order to reach the integrated luminosity goals, the first bunched beam electron cooler, with electrons from a high-current highbrightness RF accelerator [344], was successfully commissioned for the lowest RHIC energies [345].…”

“…Two cooling schemes are currently under consideration: a somewhat conventional cooling with a bunched electron beam, or variations of coherent electron cooling, where an electron beam is used as a pickup and kicker in a very high bandwidth stochastic cooling scheme [412]. The feasibility of the former, based on the electron RF photoinjector system has recently been demonstrated [344,345], but the required high beam intensities for a bunched beam electron cooler for eRHIC by far exceed the capabilities of present-day electron guns. An alternative scheme, in which the electron beam is stored in a small storage ring equipped with strong damping wigglers, is being evaluated.…”

“…A * fedotov@bnl.gov † Presently at Fermi National Laboratory natural approach of accelerating electron bunches to high energies is RF acceleration. The Low Energy RHIC electron Cooler (LEReC) is the first electron cooler based on RF acceleration of electron bunches [6,7]. With this approach now experimentally demonstrated, one can consider its application to much higher energies opening new possibilities by producing high-quality hadron beams.…”

“…A high-current high-brightness electron accelerator (layout shown in Fig. 1) was successfully commissioned in 2018 [7]. In 2019 cooling of Au ions was commissioned using electron beams with kinetic energy of 1.6 MeV to cool ions at 3.85 GeV/nucleon total energy and then using 2 MeV electron beams to cool ions at 4.6 GeV/nucleon.…”
