These proceedings contain over 80 contributions from an international group of scientists and engineers actively working on applications of fiber technology in high energy physics and related fields. Sessions included reviews of past, current and possible future detectors incorporating fiber technology for tracking and calorimetry. Special sessions covered photodetection techniques, including VLPCs, APDs and hybrid phototubes; recent advances in fiber structure, optical interconnection and mechanical support; and scintillation materials, including new developments in scintillation dyes and studies of radiation and environmental effects.Technical advances have been rapid in this promising area of detector development, and the SciFi93 proceedings serve as a useful reference on the state of the art.
