Attachment D - GCR Sim Table.pdf

This is an appendix to a federal contract solicitation (80JSC026Q0003) that defines the technical specifications for a Galactic Cosmic Ray (GCR) Simulation exposure test.

The document provides a detailed table specifying 33 separate ion beams required for a complete GCRSim exposure, organized in delivery sequence. The simulation comprises seven different ion species (H, He, Si, Ti, C, O, and Fe) across fourteen different energy levels ranging from 20 MeV/n to 1000 MeV/n. Each beam in the table is identified by ion type and corresponding energy level in MeV/n. The exposure procedure is designed to take approximately one hour to complete. The document includes a sample graph illustrating the temporal distribution of the GCR Simulation exposure, with ion flux plotted against time, showing the sequential delivery of different ion species over a one-hour period from 13:45 to 14:40. This technical specification defines the performance requirements and parameters that a contractor must be capable of delivering as part of the contract scope.
