ALSEP magnetic deflection mass spectrometer

Abstract

The scope of this document is to present a report on the development, schedule, tests, and status of the Lunar ALSEP Mass Spectrometer designed to measure the composition of the lunar atmosphere from a position on the lunar surface as part of an ALSEP array of scientific experiments. Included also is a discussion of the rationale for choosing a magnetic mass spectrometer for this program. Expenditure of funds to date is given. Projected development and delivery schedules, along with manpower requirements, and cost projections are presented to show the feasibility of building flight mass spectrometers commensurate with the Apollo 17 flight schedules.
