Future Detector Needs for High Energy Physics

High energy physics, as exemplified by the SSC, requires the analysis of increasingly complex events which occur at ever higher event rates. The SSC detectors embody an order of magnitude increase in cost and complexity. Research and development for a 500 M$ detector with 500K data channels must procede in step with accelerator design. Up to a decade of R&D at 1% per year (5M$) invested should be expected. This implies the close involvement of industry.
