  The NASA Space Radiation Laboratory (NSRL) was constructed in collaboration with NASA for the purpose of performing radiation effect studies for the NASA space program. The results of commissioning of this new facility were reported in [*]. In this report we will describe the results of the first run. The NSRL makes use of heavy ions in the range of 0.05 to 3 GeV/n slow extracted from BNL's AGS Booster. Many modes of operation were explored during the first run, demonstrating all the capabilities designed into the system. Heavy ion intensities from 100 particles per pulse up to 2×109 particles per pulse were delivered to a large variety of experiments, providing a dose range up to 70 G/min over a 5x5 cm2 area. Results presented will include those related to the production of beams that are highly uniform in both the transverse and longitudinal planes of motion [**].

  The NASA Space Radiation Laboratory (NSRL) was constructed in collaboration with NASA for the purpose of performing radiation effect studies for the NASA space program. The NSRL makes use of heavy ions in the range of 0.05 to 3 GeV/n slow extracted from BNL's AGS Booster. The purpose of the NSRL beam studies program is to develop a clear understanding of the beams delivered to the facility, to fully characterize those beams, and to develop new capabilities in the interest of understanding the radiation environment in space. In this report we will describe the first results from this program.

  The NASA SPACE RADIATION LABORATORY (NSRL) has started operations at the Brookhaven National Laboratory in 2003. The NSRL facility will be used by NASA to study radiation effects. The NSRL facility utilizes proton and heavy-ion beams of energies from 50 to 3000 MeV/n which are accelerated by the AGS_Booster synchrotron accelerator. The beams were extracted[1] ,and transported to a sample which is located 100 m downstream. To date, protons, 12C, 56Fe, 48Ti ion beams of various magnetic rigidities have been transported to the sample location. The NSRL beam transport line has been designed to employ octupole magnetic elements[2] which transform the normal (Gaussian) beam distribution on the sample into a beam with rectangular cross section, and uniformly distributed over the sample. No beam-collimation is applied along any point of the NSRL beam transport line and the beam focusing on the sample is purely magnetic. The experimental and theoretical horizontal and vertical beam envelopes of the first order optics will be presented. The theoretical beam profiles and uniformities at the location of the sample, when the magnetic octupoles are excited (third order optics), will be compared with the experimentally measured ones.
