• The instrumentation included a High-Energy Telescope The instrumentation included a High-Energy Telescope System (HETS) and a Low-Energy Telescope System System (HETS) and a Low-Energy Telescope System (LETS). The HETS covered an energy range between 6 (LETS). The HETS covered an energy range between 6 and 500 MeV/nucleon for nuclei ranging in atomic and 500 MeV/nucleon for nuclei ranging in atomic numbers from 1 through 30. In addition, electrons in numbers from 1 through 30. In addition, electrons in the energy range between 3 and 100 MeV/nucleon were the energy range between 3 and 100 MeV/nucleon were measured by this telescope and an electron telescope. measured by this telescope and an electron telescope. The LETS measured the energy and determined the The LETS measured the energy and determined the identity of nuclei for energies between 0.15 and 30 identity of nuclei for energies between 0.15 and 30 MeV/nucleon and atomic numbers from 1 to 30.
