Abstract
The cyclotron trap was developed at SIN/PSI to increase the stopping density of nega-
tively charged particle beams for the formation of exotic atoms in low pressure gases. A
weak focusing magnetic field, produced by superconducting solenoids, is used. Particles
are injected radially through the fringe field to a moderator, which decelerates them into
orbits bound by the field. Further deceleration by moderators and/or low-pressure gases
leads the particles to the center of the device, where they can be stopped or eventually
extracted. Experiments became feasible with this technique, such as those dealing with
pionic hydrogen/deuteriumat SIN/PSI.Muonic hydrogen laser experiments also became
possible with the extraction of muons from the cyclotron trap. The formation of antipro-
tonic hydrogen in low pressure targets led to successful experiments at LEAR/CERN.
