Space Radiation Research Unit, International Open Laboratory in NIRS

The radiation environment encountered by astronauts during spaceflight is far more complex than any radiation field existed on Earth. Space crew living and working in the International Space Station (ISS) are exposed to a mixed radiation field comprises primary high-energy cosmic rays, including energetic protons and heavy ions, and to secondary radiations, including energetic neutrons, produce...

Introduction to NIRS International Open Laboratory (IOL)

Brief history: IOL started at the end of 2008 and its first term ended in March 2011after 2 years and four months. Drs Hirohiko Tsujii and Ohtsura Niwa were very instrumental in the establishment of IOL. The first term IOL has three unit leaders and three distinguished scientists: These are Yukio Uchihori for the Space Radiation Research unit working with Professor Tom Hei from Columbia Univers...

International Space Station Radiation Shielding Model Development

The projected radiation levels within the International Space Station (ISS) have been criticized by the Aerospace Safety Advisory Panel in their report to the NASA Administrator. Methods for optimal reconfiguration and augmentation of the ISS shielding are now being developed. The initial steps are to develop reconfigurable and realistic radiation shield models of the ISS modules, develop compu...

Laser-plasma-based Space Radiation Reproduction in the Laboratory

Space radiation is a great danger to electronics and astronauts onboard space vessels. The spectral flux of space electrons, protons and ions for example in the radiation belts is inherently broadband, but this is a feature hard to mimic with conventional radiation sources. Using laser-plasma-accelerators, we reproduced relativistic, broadband radiation belt flux in the laboratory, and used thi...
