摘要：

A silicon sensor with 64 large area pads ('' pad '', of 1 cm(2) area) was developed to identify relativistic ions in direct measurements of the elemental composition of cosmic rays. A single-element discrimination can be achieved via an accurate measurement of the electric charge Z(2) taking advantage of the Z(2) dependence of specific ionization in silicon. Space-based or balloon-borne cosmic ray experiments of the next generation require the coverage of large sensitive areas with arrays of this kind of detectors. Preliminary results on the performance of the sensor are presented.
