Download or read book Quadrupole Ion neutral Mass Spectrometer for Space Shuttle Applications written by Donald Edward Hunton and published by . This book was released on 1986 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Quadrupole Ion/Neutral Mass Spectrometer (QINMS) was developed for the fourth flight of the Space Shuttle in June and July of 1982. Several additional instruments have been built for other programs using the same design. The instruments are designed to measure the neutral and positive ion composition in the vicinity of the Space Shuttle or similar satellites. Other experimental capabilities include the measurements of total neutral pressure, total ion density, and species kinetic energy distributions. This report describes in detail the design and construction of the QINMS instruments, the integration requirements, ground testing and calibration procedures, typical flight operations, and finally, data requirements.

Available in PDF, EPUB and Kindle. Book excerpt: A quadrupole mass spectrometer system employing a liquid nitrogen chilled zeolite pump has recently been developed for sampling positive ions at altitudes above 50 kilometers. This system was flown successfully on a Nike-Cajun rocket on 31 October 1963, and has provided the first positive ion composition measurements in the D-region. For simultaneous environmental measurements of ion and electron densities, two spherical electrostatic analyzers were included in the rocket payload. Supplemental information on ionospheric conditions was provided by a ground-based ionosonde. Due to the high sensitivity of the system approximately twenty (20) positive ion peaks were detected in the mass range 10 to 45 amu within the altitude range of 64 to 112 km. The predominant ions detected within the D-region (64 to 82 km) were 18(+), 30(+) and (37=1)(+), with 32(+) rapidly rising above 75 km approaching the abundance of 30(+) at 83 km. At 82.5 km a sharp transition occurred in the spectra, characterized by the rapid disappearance of 18(+) and 37(+) and instantaneous appearance of six (6) new ion peaks. Five (5) of these ion peaks are suggested to be the metallic ions of sodium (23(+)), magnesium (24(+), 25(+), 26(+)) and calcium (40(+)). The metallic ions all exhibited an identical altitude profile, a ten (10) km-wide peak with a maximum at 95 km, a minimum at 105 km, and then continuously increasing until apogee at 112 km.

Book excerpt: This report presents the positive-ion mass spectrometer that was part of a SWIR rocketborne electron-accelerator experiment. A quadrupole mass filter with a specially designed ion collection configuration is described. Special attention is given to the problem introduced by high positive vehicle potentials which result from the high emission currents of the electron-accelerator. A comprehensive ion mass scanning program is described and important instrument parameters are specified. Typical data is included only to illustrate instrument performance.

Available in PDF, EPUB and Kindle. Book excerpt: Explores the impact of the latest breakthroughs in cluster SIMS technology Cluster secondary ion mass spectrometry (SIMS) is a high spatial resolution imaging mass spectrometry technique, which can be used to characterize the three-dimensional chemical structure in complex organic and molecular systems. It works by using a cluster ion source to sputter desorb material from a solid sample surface. Prior to the advent of the cluster source, SIMS was severely limited in its ability to characterize soft samples as a result of damage from the atomic source. Molecular samples were essentially destroyed during analysis, limiting the method's sensitivity and precluding compositional depth profiling. The use of new and emerging cluster ion beam technologies has all but eliminated these limitations, enabling researchers to enter into new fields once considered unattainable by the SIMS method. With contributions from leading mass spectrometry researchers around the world, Cluster Secondary Ion Mass Spectrometry: Principles and Applications describes the latest breakthroughs in instrumentation, and addresses best practices in cluster SIMS analysis. It serves as a compendium of knowledge on organic and polymeric surface and in-depth characterization using cluster ion beams. It covers topics ranging from the fundamentals and theory of cluster SIMS, to the important chemistries behind the success of the technique, as well as the wide-ranging applications of the technology. Examples of subjects covered include: Cluster SIMS theory and modeling Cluster ion source types and performance expectations Cluster ion beams for surface analysis experiments Molecular depth profiling and 3-D analysis with cluster ion beams Specialty applications ranging from biological samples analysis to semiconductors/metals analysis Future challenges and prospects for cluster SIMS This book is intended to benefit any scientist, ranging from beginning to advanced in level, with plenty of figures to help better understand complex concepts and processes. In addition, each chapter ends with a detailed reference set to the primary literature, facilitating further research into individual topics where desired. Cluster Secondary Ion Mass Spectrometry: Principles and Applications is a must-have read for any researcher in the surface analysis and/or imaging mass spectrometry fields.
