Abstract We describe the (2×800 kg ) emulsion target in the CHORUS hybrid detector set-up for the search of ν μ →ν τ oscillations, together with the CERN pouring and processing facilities (upgraded for this purpose), and the techniques employed to treat the emulsions used as the active target in the experiment.

Abstract A scintillating fiber tracker system consisting of more than one million fibers has been successfully constructed and made operational for the CERN WA95/CHORUS experiment. The design and construction of the tracker system as well as its opto-electronic readout are described. The performance of the detector with high-energy muons is presented.

Research and development of fiber trackers for a nu /sub mu /- nu /sub tau / oscillation experiment are in progress. In order to satisfy required specifications, i.e., a position resolution of less than 100 mu m and an effective area of 1.6*1.6 m, dopant densities of fibers have been tuned, and a computer controlled machine for the construction of multilayer ribbons of the required size has been developed. In order to make quite large area fiber trackers, the basic characteristics of fibers of 500- mu m diameter produced by Kuraray Co. Ltd. have been checked. The light yield and attenuation length of the fiber are large enough to detect minimum ionizing particles using a reflective surface whose reflectivity is at least 60% on the other end.<<ETX>>
