ISOMAX (Isotope Magnet Experiment)

Un magneto spectrometro. Consta de un magneto superconductor de doble bobina y "driftchambers" de alta resolución.

El objetivo del instrumento es la medición de isótopos ligeros, especialmente las concentraciones de Berilio9 y Berilio10, en rangos de energía de varios GeV.

Este fue su primer vuelo.
