COUNTER TELESCOPE

Developed by University of Rochester / Office of Naval Research (ONR)

Balloon launched on 8/7/1966, from Fort Churchill Airport, Manitoba, Canada

Purpose of the flight and payload description

The telescope consists of two 1/4 -in.-thick plastic scintillators used to measure dEdx, followed by a 5-in.-thick crystal of NaI (Tl) to measure the residual energy E of stopping particles. From these measurements the charge and the mass of each particle are calculated. The accuracy of the measurements is sufficient to separate the isotopes of hydrogen and helium and to identify the nuclei of elements up to oxygen.
