A new experimental apparatus, designed principally for a high sensitivity search for ν
μ → ν
τ oscillation, has been successlly constructed and made operational by the CHORUS Collaboration for the ...CERN-WA95 experiment. It consists of a large emulsion target, a scintillating fiber tracker system with optoelectronics read-out, an air-core magnet, a set of trigger hodoscopes, a calorimeter based on the lead/scintillating-fiber technique, and a muon spectrometer. The design, construction and performance of the entire apparatus and of the different detectors are described.
The HARP detection system is a novel device which can be used for both neutron detection and for the determination of neutron and proton polarizations in nuclear physics experiments. It is currently ...under construction by the HARP collaboration, comprising Utrecht University, ISN-Grenoble and NIKHEF-Amsterdam. The instrument will be completed in 1995. A brief description of HARP is given. The physics which can be addressed with HARP is illustrated by presenting simulated data of a
12C(e,e′
