A telescope is described that is used to determine the directional characteristics of the Cherenkov radiation accompanying extensive cosmic ray air showers. The reflecting telescope has a 12.5-in. apenture, a 48-in. focal length and is of an off-axis design to permit the use of a 19-photomultiplier-tube light detection array. Pulseheight information from each tube is fed to separate, spaced inputs on a delay line which supplies the resulting signal for oscilloscope presentation. The various pulse heights provide the Cherenkov radiation directional information. An average of 75% of the Cherenkov photons arrive at the telescope within a half-angle of 2.3 deg .
