| spectrometer based on an air-core, superconducting solenoid has been constructed, tested, and demonstrated to be useful as a heavy-ion reaction-product collection and detection device. Two detector systems which measure ion energy loss, residual energy, time-of-flight, and position in the detector plane have been developed for use with the spectrometer. This spectrometer is the first which uses an air-core rather than a steel-yoked magnet. The characteristics of the two different designs are compared. The spectrometer's cylindrical symmetry, focusing properties, and large solid angle make it well-suited for several different types of experiments, including reactions with low cross sections and experiments requiring detection of reaction products emitted at small angles to the beam.;The optical properties of the spectrometer were determined using alpha-particle sources and elastically scattered particles from an accelerator beam. Simple first-order and ray-tracing calculations are shown to reproduce well the measured effects. The spectrometer was then used in the study of... |
