Abstract: A helical multiwire proportional chamber for detection of minimum ionizing particles consisting of an array of anode wires surrounded by a cathode wound in the form of a bifilar flattened helix nearly orthogonal to the anode wires and this chamber having an active area rectangular in shape, a frame comprising two pieces of plexiglass with a central cutout which forms the said active area, the anode wires being fastened to one of the frame pieces and the second frame piece being fastened to the first and the anode wires being connected in parallel to a positive high voltage supply and the cathode wire being connected to ground through a resistor.
