PERFORMANCE AND CAPABILITIES OF THE NASA SPACE RADIATION LABORATORY AT BNL

The NASA Space Radiation Laboratory (NSRL) at BNL was commissioned in October 2002 and the facility became operational in July 2003. NSRL was constructed in collab- oration with NASA for the purpose of performing radiation effect studies for the NASA space program. NSRL can ac- cept a wide variety of ions from BNL's AGS Booster; these are slow extracted with kinetic energies ranging from 0.3 to 3 GeV/n. Fast extraction from Booster to NSRL has also been developed and used. Many different beam conditions have been produced for experiments at NSRL, including very low intensity. In this report we will describe the fa- cility and its performance over the eight experimental run periods that have taken place since it became operational. We will also describe the current and future capabilities of the NSRL. designed to accelerate protons and heavy ions. It is a 201.78 m circumference separated function alternating gra- dient synchrotron that can operate up to a maximum rigid- ity of 16 Tm. In its experiments, NRSL has used iron, titanium, chlorine, silicon, oxygen, and carbon ions, and protons delivered from Booster at kinetic energies rang- ing from 0.3 to 3.0 GeV/nucleon. Resonant extraction is used in order to deliver a continuous stream of particles. Fast extracted beam also has been developed and used for a small set of experiments. Table 1 lists the ion species, max- imum beam intensities, beam sizes, and maximum dose rates delivered to the NSRL experiments. For experiments requiring low intensity, the minimum flux density operated on target is on the order of . The maxi-
