Ultra heavy $(Z>30)$ and heavy $(10⩽Z⩽30)$ cosmic-ray measurements on ACCESS with the charge (Z) identification module (ZIM)

The Charge (Z) Identification Module (ZIM) for ACCESS has as its primary objective the measurement of the cosmic-ray abundance of every individual element in the interval $10⩽Z⩽83$ with cleanly resolved individual element resolution and with sufficient collection power to give excellent statistical significance. This instrument will, for the first time, determine the full element-by-element composition of cosmic rays, throughout the heavy two-thirds of the periodic table, providing definitive tests of theories of sites and mechanisms of cosmic-ray acceleration. We expect that detectors with this UH configuration will serve as the Charge Module for the full ACCESS instrument. In this paper we describe the science objectives of ZIM and the measurements that can be achieved with this instrument.
