About this file
This is a Statement of Work (SOW) for the purchase of an ion gun system to be integrated into the Space Radiation Effects in Dust and Ice (Space REDI) experimental chamber at NASA's Goddard Space Flight Center (GSFC) Astrochemistry Lab in Greenbelt, Maryland.
The ion gun system will enable experimental analysis of hydrogen, helium, and oxygen radiation effects on regolith samples and characterization of secondary ion and neutral species ejected through sputtering processes. The system will support research on ion interactions with lunar surfaces and other airless bodies, volatile species detection relevant to lunar in-situ resource utilization (ISRU) applications and astronaut safety, organic molecule characterization for astrobiology, and extraterrestrial material interactions. The required equipment includes an ion gun head, monitoring and control hardware, multi-gas compatible gas manifold, mechanical bellows adjuster for beam positioning, differential pumping module with total pressure gauge, and spare filament kits. System specifications include 0.5 to 5.0 kev beam energy, 100 micron spot size, 0.1 to 800 nA current density, oxygen compatibility, neutral dump capability, beam scanning functionality, easily replaceable twin filaments, and DN35 Conflat flange mounting. The system is specifically designed to integrate with the recently installed Hiden EQS-1000 SIMS/SNMS instrument. Equipment will be purchased in Fiscal Year 2026 with approximately four months leadtime following purchase order completion. After installation, the equipment will be used on an ongoing basis without requiring manufacturer servicing.

STATEMENT OF WORK
1. Objective/Requirements The ion gun system will allow for the experimental analysis of H, He, and O radiation effects on regolith samples and characterization of the secondary ion and neutral species ejected due to sputtering processes. These experiments will be used to understand ion interactions with the lunar surface and other airless bodies such as asteroids and comets. Detection of sputtered species will allow for the characterization of volatile species (e.g., water and methane) in contact with regolith relevant to lunar ISRU applications and astronaut safety concerns, characterization of organic molecules relevant to astrobiology, and better understanding of extraterrestrial material interactions with ions relevant to numerous priority science questions.
2. Characteristics, Scope, and Specs
The purchase will consist of the following items:
Ion gun head, monitoring and control hardware, a gas manifold compatible with multiple gases, mechanical bellows adjuster for beam positioning, differential pumping module with total pressure gauge, and spare filament kits.
The system specs are as follows:
0.5 to 5.0 kev beam energy 100 Micron Spot Size
0.1 to 800 nA Current Density Oxygen Compatible Neutral Dump Beam scanning Easily Replaceable Twin Filaments DN35 Conflat Flange Mounting
This system will be integrated into the newly built Space Radiation Effects in Dust and Ice (Space REDI) experimental chamber in the GSFC Astrochemistry Lab. This system is specifically designed to work with the recently installed Hiden EQS-1000 SIMS/SNMS instrument.
3. Place of Performance Goddard Space Flight Center (GSFC), Greenbelt, Maryland.
4. Period of Performance Equipment with be purchased in FY26 with a leadtime of ~4months after completion of the purchase order. After installation, the equipment will be used on an ongoing basis without the need for manufacturer servicing.
