 note = {The origin of Galactic Cosmic Rays (GCRs) nuclei is still unknown. The precise observation of ultra heavy nuclei (Z is greater than or equal to 30) in GCRs is important to resolve the problems remained in cosmic ray astrophysics. Observation program of these nuclei in GCRs is proposed with the use of high performance Solid-State Track Detector (SSTD) on board long-duration balloon or International Space Station (ISS). The program focuses to measure the isotopic abundance above iron-peak elements and the composition of the rare ultra heavy nuclei up to actinide elements with relativistic energy. The observation of their nuclear composition covers a wide range of scientific themes including studies of nucleosynthesis of cosmic ray sources, chemical evolution of galactic material, the characteristic time associated with cosmic rays, such as heating and acceleration mechanism of cosmic ray particles. In order to achieve the objectives, long-duration balloon and/or ISS capable of carrying very large scientific payloads for long extended period is thought as best suited. The possible approach is based on a large telescope array consisting of modularized SSTD stacks., 資料番号: AA0063706014},
