Measurements of nuclear fragmentation cross sections and of particle production in thick targets are needed for the development of space radiation shielding. Cross sections are used as source terms for models of fragmentation and transport, and thick target measurements for model validation and to evaluate candidate shielding materials and concepts. Here we briefly review how HIMAC ion beams have been used to simulate elements of the space radiation field for cross section and thick target measurements.

Key words: HIMAC (Heavy Ion Medical Accelerator in Chiba); nuclear fragmentation; thick target measurement; space craft shielding
