EXPERIMENTAL OBSERVATIONS OF
THE COSMIC RAY ELECTRON SPECTRUM

Among the many diverse avenues of research conducted in the field of physics
at the University of Chicago is the study of cosmic rays. Numerous experiments
have been designed and built here at the Enrico Fermi Institute, Laboratory for
Astrophysics and Space Research to investigate cosmic rays. Among the many
experiments, several have been designed to observe cosmic ray electrons. Prior
to results gained through these experiments, very little was known about cosmic
ray electrons. Two unique experiments have provided the means to monitor the
time dependence and the long term solar modulation of cosmic ray electrons for
nearly two decades. Such observations have provided insight into the structure
of our heliosphere.
