Small Cloud Chamber for Use with Unmanned Balloons

Abstract

A small lightweight cloud chamber, designed for high altitude cosmic-ray researches, has been operated successfully in unmanned balloon flights up to an 80,000-ft. altitude. In view of the current interest in high altitude cosmic-ray studies, it seems appropriate to describe briefly some of the design features of the present apparatus.
