Initial images from a 24-wire liquid xenon γ-camera

A prototype liquid xenon γ-camera has been constructed and preliminary results obtained. The sensitive volume is 7 cm × 7 cm in area and 4.5 cm thick. Orthogonal coordinates for each interacting γ-ray are provided by 24 anode wires 5 μ in diameter spaced 2.8 mm apart and 24 cathode strips.
