NASA SBIR 01-II Solicitation

FORM 9B - PROPOSAL SUMMARY


PROPOSAL NUMBER: H3.03-8501 (For NASA Use Only - Chron: 013498 )
PHASE-I CONTRACT: NAS10-01066
PROPOSAL TITLE: A Compact, Low-Power Time-of-Flight Mass Spectrometer

TECHNICAL ABSTRACT (LIMIT 200 WORDS)
Many hazardous gases that NASA needs to monitor on and around space vehicles during launch could be detected using mass spectrometers that need operate over only a limited mass range. But, stringent requirements of low weight and low power operation, plus the ability to tolerate high G-forces and excessive vibration prevent the ready adaptation of existing, commercial mass spectrometers to these applications. This Phase I SBIR project successfully tested a novel, compact, inexpensive, low power, time-of-flight mass spectrometer (TOFMS) for quantitative measurement of hydrogen, helium, nitrogen, oxygen, and argon. The key insight behind our approach is recognizing that a useful TOFMS can be built incorporating a short flight tube that is operated at low energies. Phase I proof-of-principle experiments provide the essential information needed to design and build a prototype instrument that will be delivered to NASA KSC at the end of Phase II. We anticipate that deliverable will meet most of the target parameters specified in the Phase I solicitation: operation between 2 and 40 amu; a measurement dynamic range of 1,000,000; less than 3500 cubic centimeter volume; and, less than 10 kg total weight.

POTENTIAL COMMERCIAL APPLICATIONS
The planned technology also has commercial application as a low cost, portable sensor for leak detection, hygrometry, breathing air monitoring, and residual gas analysis.
