使用Nd:YAG激光器在Al、Cu、Ge、Ag和月球模拟物的靶上产生等离子体。1×109 W/cm 2的离子能量在550 ~ 900 eV之间。其中一些离子沿着11.1米的真空管向下行进到离子阱1米飞行时间光谱仪,产生月球模拟物的质谱,展示了在相当远的距离上分析目标的能力。
A Nd:YAG laser is used to produce a plasma on targets of Al, Cu, Ge, Ag, and a lunar simulant. Ion energies for 1×109 W/cm2 were found to be between 550 and 900 eV. Some of these ions travel down a 11.1‐m evacuated tube to an ion trap 1‐m time‐of‐flight spectrometer producing a mass spectrum of a lunar simulant, demonstrating the ability to analyze targets at significant remote distances.
