The effect of latent track ageing on the charge resolution that can be achieved in polycarbonate Solid State Nuclear Track Detectors exposed for long periods in space is investigated. Several exposures of polycarbonate stacks to different ultra heavy relativistic ions have been undertaken at the Berkeley Bevalac in order to study this effect. Following an increase in signal strength in the first few weeks after exposure, our results do not indicate any further significant change during a period of nearly three years. The implications of these results for the expected charge resolution from the Ultra Heavy Cosmic Ray Experiment are discussed. © 1989.
