Simulation of a miniature, low-power time-of-flight mass spectrometer for in situ analysis of planetary atmospheres
2008
Micro (MEMS) and Nanotechnologies for Space, Defense, and Security II
We are implementing nano-and micro-technologies to develop a miniaturized electron impact ionization mass spectrometer for planetary science. Microfabrication technology is used to fabricate the ion and electron optics, and a carbon nanotube (CNT) cathode is used to generate the ionizing electron beam. Future NASA planetary science missions demand miniaturized, low power mass spectrometers that exhibit high resolution and sensitivity to search for evidence of past and present habitability on
