The following is a report on the study and development of a system of magnetostrictive read-out wire spark chambers designed for recording high energy events involving high statistics in a magnetic field. The apparatus, consisting of a large 10 kgauss magnet, five spark chambers and their read-out wires, together with associated H.T. and read-out electronics, is described in full. A brief outline of the analysis procedure is given. The characteristics of the individual components of the system are investigated separately. Particular emphasis is placed on the study of the behaviour of the read-out wires in magnetic field; the results of this study provided the necessary criteria for shimming the 10 kgauss magnet to achieve the optimal field configuration for the wires. Finally, the performance of the whole system is evaluated using data taken during operation in a test beam. The conclusions are that although the present system is unsuitable for the recording of multi-track events, with twice the number of chambers, it should be possible to record two or even three track events successfully.
