Abstract: | The NASA Space Radiation Laboratory (NSRL) located at Brookhaven National Laboratory (BNL) is a center for space radiation
research in both the life and physical sciences. BNL is a multidisciplinary research facility operated for the Office of Science
of the US Department of Energy (DOE). The BNL scientific research portfolio supports a large and diverse science and technology
program including research in nuclear and high-energy physics, material science, chemistry, biology, medial science, and nuclear
safeguards and security. NSRL, in operation since July 2003, is an accelerator-based facility which provides particle beams
for radiobiology and physics studies (Lowenstein in Phys Med 17(supplement 1):26–29 2001). The program focus is to measure the risks and to ameliorate the effects of radiation encountered in space, both in low
earth orbit and extended missions beyond the earth. The particle beams are produced by the Booster synchrotron, an accelerator
that makes up part of the injector sequence of the DOE nuclear physics program’s Relativistic Heavy Ion Collider. Ion species
from protons to gold are presently available, at energies ranging from <100 to >1,000 MeV/n. The NSRL facility has recently
brought into operation the ability to rapidly switch species and beam energy to supply a varied spectrum onto a given specimen.
A summary of past operation performance, plans for future operations and recent and planned hardware upgrades will be described.
Work performed under the auspices of the auspices of the US National Aeronautics and Space Administration and the US Department
of Energy. |
