Fine grained hodoscopes based on scintillating optical fibers
Abstract
Scintillating optical fibers were developed and tested for use in a fine grained hodoscope for experiments in high energy physics. The need for such a device in experiments in high rate environments is discussed and the process of drawing and cladding a plastic scintillator to form scintillating optical fibers is described. The test procedures used to evaluate the resultant fibers both in the laboratory and at the accelerator are given. Three possible readout schemes individual photomultiplier tubes, avalanche photodiodes, and microchannel plates with segmented anodes are considered. The results of this study are then presented. The present status of the project is summarized, in which it is pointed out that significant improvement in useful fiber length was achieved. The difficulty of quality control in fiber production remains a serious limitation, and a satisfactory readout scheme with good optical coupling between many hodoscope elements and photodetectors is not yet achieved.
