[en] The performance of a low pressure position sensitive multistep parallel plate avalanche counter designed for studying the angular distribution of fission fragments in high energy α-induced fission of heavy elements is reported. The detector consists of a ionization collection and amplification stage followed by a multiwire proportional counter. The horizontal position spectrum of fission fragments from a 225Cf source is given. A resolution of less than 1 mm was achieved. (M.G.B.)
