BOLIVIAN AIR SHOWER JOINT EXPERIMENT (CHACALTAYA COLLABORATION).

Abstract

The Bolivian Air Shower Joint Experiment (BASJE) is a cooperative effort of Japanese, Bolivian and U. S. physicists to study the phenomena of cosmic ray air showers under half an atmosphere. The experiment is set up on Mt. Chacaltaya near La Paz, Bolivia at an altitude of 17,600 feet above sea level. The prime motivation for the experiment has been that air showers generated by primary gamma rays (as opposed to ordinary showers generated by protons or heavier nuclei) could be detected and identified by pecularities in the features of the showers observed. The air shower array was designed for this purpose and features a large (60 m2) shielded detector and an accurate means of determining the arrival direction of the showers. This report covers the period September 1, 1966--August 31, 1968. The document includes a status report on the gamma ray search. It also includes summaries of two other efforts which have been of recent interest to the collaborators of the experiment.
