The Indiana Cooler: A Retrospective

Abstract

From 1983 to 2002, the Indiana Cooler was constructed and operated at the Indiana University Cyclotron Facility. During that period, a relatively small group of people built an accelerator complex, explored the new technology of electron cooling, and demonstrated its usefulness in nuclear and particle physics. This review recounts the history of the project, describes the facility, and summarizes the scientific results in atomic, nuclear, and particle physics, and in the physics of beams.

Signatures of three-nucleon interactions in few-nucleon systems

“…At higher energies, one uses cyclotrons to accelerate particles up to a few hundred MeV. At IUCF, Uppsala and Jülich, particles are also accelerated in rings [182]. Since the beam has gone through a secondary stage of acceleration to achieve higher energies, one should perform polarimetry of the beam in order to determine the degree of the polarization of the beam.…”

“…Due to kinematical constraints (low energy of the outgoing particles), the angular ranges of the measurements are also generally more limited than in the case of other observables. The measurements of spin-correlation coefficients have been done only at IUCF with the help of the polarized target used in the ring [182]. An overview of the IUCF-PINTEX setup can be found in [207] describing extensively the polarized beams and targets for all their double spin experiments.…”
