COSMIC RAY GROUP .
CALIFORNIA UNIV BERKELEY
The work is divided into two general categories research in high energy particle physics and research on cosmic rays and solar particle emissions. High energy physics was concerned with the observation of various particles produced in high-energy nuclear interactions, first using cosmic rays as the source of such particles and more recently using the accelerator at CERN, Geneva. The research on cosmic rays was concerned with temporal and spatial variations of cosmic rays studied by means of neutron monitors located at Berkeley and a neutron monitor which voyaged between San Francisco and Australia. Routine observations of neutron cosmic ray intensity were made for a period of several years and were correlated with cosmic ray increases that occurred during solar flares. Numerous studies were made of the solar particle radiation at high altitudes through balloon flights.
