Abstract A programme has been in progress in our laboratory to determine the performance of a cylindrical proportional counter filled with argon or xenon at pressures up to 30 atmospheres, using methane as the quenching agent. The successful operation of a prototype counter has led to the design of a large area balloon-borne detector for hard x-ray astronomy. The ultra high pressure in an array of cylindrical proportional counter modules, together with the large dimensions possible, will enable us to fabricate a detector with very high efficiency and sensitivity, capable of extending its energy response well beyond the limits of contemporary flow detectors. The details of our investigations and the proposed detector are described.
