“…When the stored-beam parameters cross the condition for a depolarizing resonance at the appropriate rate, the spins are reversed in a process called adiabatic fast passage. The ability to flip the spin of the stored beam is clearly important to nuclear experiments, and thus extensive tests of this technique were carried out (60)(61)(62)(63)(64)(65)(66). In these studies, an induced resonance was moved by ramping its driving rf frequency.…”

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.

“…When accelerating the beam to higher energies, eventually depolarizing resonances have to be crossed. In order to preserve the polarization, imperfection resonances may be enhanced to affect a complete spin flip [10], while a sudden tune change may be used to jump over intrinsic resonances (as is done at COSY). Another method to avoid depolarizing resonances involves the use of spin rotators (so-called Siberian snakes).…”
