This paper describes the development of the Solar Wind Implanter (SWIM) to implant helium into JSC-1A lunar simulant for volatile extraction system testing. The SWIM device accelerates helium ions to simulate solar wind conditions and implants them into regolith simulant. The study focuses on helium implantation processes and their implications for lunar volatile extraction systems. This paper describes the development of the Solar Wind Implanter (SWIM) system for implanting helium into JSC-1A lunar regolith simulant to test volatile extraction systems. The system uses electrostatic grids and tungsten filaments to accelerate helium ions into the simulant. Experimental results show helium release patterns similar to Apollo 11 regolith and other lunar analog materials. This paper discusses helium implantation into JSC-1A lunar simulant for volatile extraction system testing. It references prior work on lunar volatiles, extraction systems, and helium-3 resources but does not describe new experiments or properties of JSC-1A.
These are the records this paper contributes to the simulant, returned sample, method, and property browsers.
