The Isotopic Composition of Cosmic-Ray Iron and Nickel
Observations from the Cosmic Ray Isotope Spectrometer (CRIS) on ACE have been used to derive contraints on the locations, physical conditions, and time scales for cosmic-ray acceleration and transport.

Energetic (sup 3)He in the Interplanetary Medium and its Acceleration by Shocks
Observations of number of relatively large solar energetic particle (SEP) events that have occurred since the launch of ACE in August 1997 have shown that the ratio of (sup 3)He/(sup 4)He can be enhanced over the solar wind value by more than an order magnitude in such events.

Constraints on the Time Delay Between Nucleosynthesis and Cosmic-Ray Acdeleration from Observations of (sup 59)Ni and (sup 59)Co
Measurements of the abundances of cosmic-ray (sup 59)Ni and (sup 59)Co are reported form the Cosmic Ray Isotope Spectrometer (CRIS) on the Advanced Composition Explorer (ACE).

Two-Dimensional Interdigitated Pixel Detector for Energetic Particle Spectrometers
This paper describes a type of cosmic ray detector suitable for the construction of a small, low power space-based instrument to detect the energy and isotope of energetic nuclei, such as those produced by solar flares. The detector is similar to previous types of silicon PIN detectors where the fully depleted body of the wafer comprises intrinsic region of the PIN structure. The novel aspect of this detector is that the one surface is divided into a two-dimensional array of pixels, and that the collected holes are divided between a row and a column collector in each pixel, yielding both dimensions of position information from this side of the detector.

A particle astrophysics magnet spectrometer facility for Space Station
Planning for and design tradeoff studies related to the particle astrophysics magnet spectrometer known as Astromag are presented. This facility is being planned for the Space Station Freedom and address questions regarding the origin and acceleration of cosmic rays, explore the synthesis of elements by making detailed measurements of cosmic ray isotopic composition, and search for evidence of antimatter and other cosmologically significant particles. This work was supported by an international study team which includes particle physicists and cosmic ray physicists.
