Abstract
We describe the development of new high-resolution Cerenkov detectors for use in an
instrument designed to measure the isotopic composition of cosmic ray nuclei from Be to
Ni (Z = 4 to 28). The latest version of this balloon-borne instrument contains two new
large-area, (-0.5 m^2) Cerenkov detectors, one composed of Teflon and a second of Pilot-
425. Through the use of improved light-collection techniques, and a novel radiator design,
the photoelectron yield of these counters has been upgraded significantly over that of
earlier counters. In particular, the greatly improved Cerenkov light yield achieved with
Teflon makes it an attractive alternative to available liquid counters of similar index of
refraction. Laboratory tests of these and other Cerenkov radiators are described, along
with estimates of the mass resolution that can be achieved.
