摘要：

As part of the NA24 experiment at the CERN-SPS a photon position detector serves to separate direct photons from abundantly produced pi **0 decay photons: electromagnetic showers are measured with an energy- and position-resolution sufficiently good to give a two-gamma resolving power of 1. 2 cm. The shower detector covers 3 multiplied by 3 m**2 and consists of 12 layers of triangular proportional tubes (7. 73 mm pitch) sandwiched with lead (altogether 9. 6X//0). For eight layers the analog information is provided by an ADC system. Ambiguities are resolved by the digital information of four additional layers inclined by 45 degree . Prototypes were built in order to test gas mixtures and electronics. The electromagnetic shower development in the PPD and the prototypes are reproduced by Monte Carlo calculations. The homogeneity of the PPD has been checked by calibration measurements.
