The University of Chicago Measurement in Space of Cosmic Rays at Energies above 0.5 MEV

The three-fold coincidence telescope is a compact, flexible instrument providing cosmic-ray measurements related to the charged-particle flux at a well-defined low-energy cutoff. The output to the space-crafts data-handling system may be in either analog or digital form. The experimental results to date have provided useful information of the space environment at distances from 200 miles to some 22 million miles from Earth.
