Abstract A lange experiment on extensive air showers was recently set up at Cornell University, similar to that at M. 1. T., which employs 15 plastic scintillators. Five of the detectors are near the center of the array at spacings of 3 to 80 m. Five others are spaced about the center on a circle of 150- m radius. and the remaining five are on a circle of 500-m riulius. The main component of the apparatus is a magnetic meson spectrometer located near the central counters. When a lange shower occurs, a photograph is taken of a bank of 15 oscillograph tubes upon which all the scintillator pulses are registered. The times and heights of the pulses determine the direction and location of the shower axis and the size of the shower. If a meson has been recorded simultaneously, this fact and the approximate meson energy are registered on the same film by means of neon bulbs. With the oscilloscope method about 200 showers per day are exanfined. (A.C.)
