Download or read book Bias and Signal Processing Circuits for a Mass Spectrometer in the Project EXCEDE SWIR Experiment written by Raimundas Sukys and published by . This book was released on 1975 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bias and signal processing circuits designed for a mass spectrometer in the project EXCEDE: SWIR experiment are described in this report. In this experiment a rocket-based electron gun injects a stream of electrons into the atmosphere. This causes a buildup of a positive charge on the vehicle severely limiting the measurement capability of the positive ion mass spectrometer. To overcome this limitation under a wide range of vehicle potential buildup a varying negative bias voltage is applied to the front plate and the grid-rod structure of the quadrupole mass filter. Circuits generating and controlling the variable bias voltages are described in detail. Logarithmic data signal processing circuits and modifications, dictated by the bias requirements, of some already existing circuits are presented. (Author).
Download or read book EXCEDE II written by Robert R. O'Neil and published by . This book was released on 1976 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: EXCEDE is a program designed to study atmospheric infrared emissive processes induced by a rocketborne electron accelerator in the altitude range 80 to 140 km. The primary scientific interest is the investigation of the detailed production and loss processes of various excited electronic and vibrational states resulting in optical and infrared emission as energetic primary electrons and their secondary and all subsequent generation electrons are stopped in the atmosphere. The electron-induced optical and infrared emissions simulate natural auroral processes with the very significant advantage that the dosing conditions of electron energy and power, deposition volume and altitude, and dosing duration are parameters that may be controlled and monitored. To date, three payloads have been launched in the EXCEDE series of artificial auroral experiments. The program status is reviewed and a follow on experiment, EXCEDE II, is described. Both rocket-based and ground-based imaging and spectro-radiometric instruments are proposed. The feasibility of the scientific approach, the magnitude of the atmospheric emissions, the capabilities of ground-support systems, and the engineering design of the proposed experiment are extensions of the technology base established in the earlier EXCEDE launches.

This book was released on 2012-12-06 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the Fifth International Confer ence on Secondary Ion Mass Spectrometry (SIMS V), held at the Capitol Holiday Inn, Washington, DC, USA, from September 30 to October 4, 1985. The conference was the fifth in a series of conferences held bienni ally. Previous conferences were held in Miinster (1977), Stanford (1979), Budapest (1981), and Osaka (1983). SIMS V was organized by Dr. R.J. Colton of the Nayal Research Lab oratory and Dr. D.S. Simons of the National Bureau of Standards un der the auspices of the International Organizing Committee chaired by Prof. A. Benninghoven of the Universitat Miinster. Dr. Richard F.K. Herzog served as the honorary chairman of SIMS V. While Dr. Herzog is best known to the mass spectrometry community for his theoretical development of a mass spectrometer design, known as the Mattauch-Herzog geometry, he also made several early and impor tant contributions to SIMS. In 1949, Herzog and Viehbock published a description of the first instrument designed to study secondary ions pro duced by bombardment from a beam of ions generated in a source that was separated from the sample by a narrow tube. Later at the GCA Cor poration, he brought together a team of researchers including H.J. Liebl, F.G. Riidenauer, W.P. Poschenrieder and F.G. Satkiewicz, who designed and built, and carried out applied research with the first commercial ion microprobe.

Download or read book Advances in Mass Spectrometry written by J. D. Waldron and published by Elsevier. This book was released on 2017-01-31 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Mass Spectrometry documents the proceedings of a Joint Conference on Mass Spectrometry held at the University of London, Great Britain on September 24-26, 1958. This compilation reviews the instruments, techniques, applications, and major developments in mass spectrometry over the past years. The topics discussed include the performance and image error correction of the new stigmatic focusing mass spectrograph; correction of second order aberrations in inhomogeneous magnetic sector fields; and high sensitivity solid source mass spectrometry. The isotope dilution analysis; digitization of mass spectra; ionization potentials of alkyl and halogenated alkyl free radicals; and negative ion formation and electric breakdown in some halogenated gases are also elaborated. This book likewise covers the mass spectrometer as a geological instrument and absorption and desorption of gases in the ionized state on metal and glass surfaces. This publication is a useful reference to students and researchers conducting work on mass spectrometry.

Available in PDF, EPUB and Kindle. Book excerpt: The latest edition of a highly successful textbook, Mass Spectrometry, Third Edition provides students with a complete overview of the principles, theories and key applications of modern mass spectrometry. All instrumental aspects of mass spectrometry are clearly and concisely described: sources, analysers and detectors. Tandem mass spectrometry is introduced early on and then developed in more detail in a later chapter. Emphasis is placed throughout the text on optimal utilisation conditions. Various fragmentation patterns are described together with analytical information that derives from the mass spectra. This new edition has been thoroughly revised and updated and has been redesigned to give the book a more contemporary look. As with previous editions it contains numerous examples, references and a series of exercises of increasing difficulty to encourage student understanding. Updates include: Increased coverage of MALDI and ESI, more detailed description of time of flight spectrometers, new material on isotope ratio mass spectrometry, and an expanded range of applications. Mass Spectrometry, Third Edition is an invaluable resource for all undergraduate and postgraduate students using this technique in departments of chemistry, biochemistry, medicine, pharmacology, agriculture, material science and food science. It is also of interest for researchers looking for an overview of the latest techniques and developments.

Download or read book Secondary Ion Mass Spectrometry SIMS III written by A. Benninghoven and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the biannual meetings in MUnster (1977) and Stanford (1979) the Third International Conference on Secondary Ion Mass Spectroscopy was held in Budapest from August 31 to September 5, 1981. The Conference was attended by about 250 participants. The success of the 1981 Conference in Budapest was especially due to the excellent preparation and organization by the Local Organizing Committee. We would also like to acknowledge the generous hospitality and cooperation of the Hungarian Academy of Sciences. Japan was chosen to be the location for the next conference in 1983. SIMS conferences are devoted to two main issues: improving the application of SIMS in different and especially new fields, and understanding the ion formation process. Needless to say, there is a very strong interaction be tween these two issues. The major reason for the rapid increase in SIMS activities in the last few years is the fact that SIMS is a powerful tool for bulk, thin-film, and surface analysis. Today it is extensively and successfully applied in such different fields as depth profiling and imaging of semiconductor devices, in isotope analysis of minerals, in imaging biological tissues, in the study of catalysts and catalytic reactions, in oxide-layer analysis on metals in drug detection, and in the analysis of body fluids.
