Nucleus-nucleus collisions

Current research falls into the following five principal areas: (1) relativistic heavy ion research (DOE support); (2) search for highly ionizing particles in e+e- annihilation (PEP-2 experiment, supported by NSF) and in pp anti annihilation (NSF support); (3) cosmic-ray astrophysics (NASA and NSF support); (4) new detectors (NASA support); and (5) search for grand-unification magnetic monopoles (NSF and Calspace support). Among the experiments in progress or planned for the next two years at the Bevalac are a high-energy gamma-ray experiment with 100 times higher collecting power; detection of many new nuclides delineating the neutron dripline; hadron calorimetry with large solid angle; search for Lee-Wick matter in U-U collisons; measurement of higher order electrodynamics in dE/dx and Cerenkov radiation by ions up to U; detailed studies of anomalons, including measurement of lifetimes, with detectors capable of resolving nonintegral charge; and determination of the response of plastic track detectors to relativistic ions up to U (the latter being of crucial importance for the proof that cosmic rays come from freshly synthesized supernova debris)
