The NASA Space Radiation Laboratory (NSRL) at BNL uses many different beams to do experiments associated with evaluating the possible risks to astronauts in space environments. This facility became operational in 2003 and operates from the AGS Booster synchrotron. In order to simulate the space radiation environment some of these experiments need to make use of beams of various energies. To simulate solar flare events, we implemented the Solar Particle Simulator in 2005. This system put in modifications to the accelerator controls to allow beam energies to be changed automatically, enabling target samples to be irradiated with many energies of the same type of ion, without having to make use of degraders. To simulate Galactic Cosmic events, they need to also be able to automatically change the ions used to irradiate a single sample. This project aims to allow NSRL to change ions as well as beam energies within a very short period of time. To do this requires modifications to existing controls as well as building new controls for a laser ion source. In this paper we describe NSRL, our plans to implement the Galactic Cosmic Event Simulator, and the status of the laser ion source.
