Journal ArticleDOI
Theoretical and experimental aspects of the energy loss of relativistic heavily ionizing particles
TL;DR: In this article, the theory of the electromagnetic interactions between rapidly moving charged particles and the matter through which they pass is reviewed and the stopping power of the projectile and the response of the absorbing medium to the excitation caused by the projectile is considered.
Journal ArticleDOI
Cosmic ray isotope abundances from chromium to nickel
TL;DR: In this article, the isotopic composition of the iron-group elements Cr, Mn, Fe, and Ni with an average mass resolution of 0.65 amu for the energies 320-500 MeV per amu at the detector.
Journal ArticleDOI
Energy straggling eliminated as a limitation to charge resolution of transmission detectors
G. Tarle,S. P. Ahlen,P. B. Price +2 more
TL;DR: In this paper, it is shown that this limitation can be overcome with a new nuclear track detector, CR-39(DOP), and that the charge resolution of this detector exceeds that of any other, including semiconductor diodes.
Journal ArticleDOI
Can we detect antimatter from other galaxies
TL;DR: In this paper, a particle detection technique employing well established principles of high order quantum electrodynamics for searching for antimatter in cosmic rays is described, and shown to have both collecting power and resolution superior to conventional alternatives.
Journal ArticleDOI
Search for nonintegrally charged projectile fragments in relativistic nucleus-nucleus collisions
TL;DR: Using dioctyl-phthalate-doped CR-39 plastic track detectors with charge resolution of approximately 0.06e, the first dynamic search for fractionally charged particles bound to nuclei was performed in this article.
