A major problem for experimenters designing detectors for use at ISABELLE is the high interaction rate, one event every 25 nanoseconds at a luminosity of 10/sup 33/ cm/sup -2/ sec/sup -1/. Typical multiplicities range from a few at large angles (> approximately 45/sup 0/) to approximately 10 nearer the forward direction. This implies average rates as high as a particle every few nanoseconds. For experiments which require high luminosities, detectors must be designed which have very short (approximately 1 nsec) response time and/or intercept a small solid angle per element. These requirements are met by fine-grained scintillation counter hodoscopes. However, it is, at present, impractical to maintain a 10,000 element hodoscope array because of the difficulty of light piping, the complexity and expense of maintaining that many phototubes, and the problems of packaging and readout. Several developments which promise to make such large arrays feasible are discussed.
