Work with a Noble Gas Scintillation Counter (thesis).

Book Description
Submitted to United States Naval Postgraduate School Monterey, Calif. More than 1450 runs were made and analyzed with a noble gas scintillation counter and its associated equip ment. The counter itself consists of a special photomultiplier tube looking into a scintillation chamber, and is used in conjunction with a vacuum and filling system, an output-pulse amplification system, and a 12-channel pulse-height analyzer. Because gas contamination presented a major problem, a dynamic gas-purification system was desigaed and effectively employed. Adequate mixing of the binary mixtures of argon and helium was a second major problem and was solved by a specially designed diaphragm pump and by close control of the flow of the constituent gases. Although the results obtained were most conclusive with pure argon and pure helium, sufficient work was completed on intermediate mixtures of these two gases to indicate that further investigation in this direction is appropriate. It is planned that future investigations will be made using xenon and krypton. (auth).
Noble Gas Detectors

ISBN: 3527609636
Category : Science
Languages : en
Pages : 362
Book Description
This book discusses the physical properties of noble fluids, operational principles of detectors based on these media, and the best technical solutions to the design of these detectors. Essential attention is given to detector technology: purification methods and monitoring of purity, information readout methods, electronics, detection of hard ultra-violet light emission, selection of materials, cryogenics etc. The book is mostly addressed to physicists and graduate students involved in the preparation of fundamental next generation experiments, nuclear engineers developing instrumentation for national nuclear security and for monitoring nuclear materials.
A Low-pressure Noble-gas Scintillation Counter for Heavy-ion Detection
Author: M. MuttererThe Theory and Practice of Scintillation Counting
Author: J. B. BirksPublisher: Elsevier
ISBN: 1483156060
Category : Technology & Engineering
Languages : en
Pages : 685
Book Description
The Theory and Practice of Scintillation Counting is a comprehensive account of the theory and practice of scintillation counting. This text covers the study of the scintillation process, which is concerned with the interactions of radiation and matter; the design of the scintillation counter; and the wide range of applications of scintillation counters in pure and applied science. The book is easy to read despite the complex nature of the subject it attempts to discuss. It is organized such that the first five chapters illustrate the fundamental concepts of scintillation counting. Chapters 6 to 10 detail the properties and applications of organic scintillators, while the next four chapters discuss inorganic scintillators. The last two chapters provide a review of some outstanding problems and a postscript. Nuclear physicists, radiation technologists, and postgraduate students of nuclear physics will find the book a good reference material.
Particle Discrimination Using a High-Pressure Xenon Gas Scintillation Detector

Book Description
This work presents results on the study of the scintillation of high-pressure Xenon gas irradiated by various sources. Noble gases such as Xenon give off characteristic scintillation light when irradiated. The goal of the study was to develop a characteristic based on the scintillation time response of Xenon gas that would reliably discriminate between events from different types of primary radiation (neutron or gamma). A reliable discrimination characteristic would enable the development of room temperature, gas phase detectors for use in the search for Galactic Dark Matter. The surprising result of the present work was that a reliable discrimination characteristic existed for distinguishing x-ray, gamma ray, and alpha particle events. Results for neutrons were negative. This was due to several factors: Ionization tracks in xenon generally form two roughly cylindrical regions. A region near the center of the track, called the core, has very dense ionization. An outer region, called the penumbra, has sparse ionization. In Xenon, recombination of ions and the subsequent scintillation from the penumbra region happens slowly and can be easily distinguished from scintillation that happens in the core region. Nuclear recoils resulting from neutron collisions that give recoil energies in the same range as that predicted for WIMP-nuclear collisions are of such low energy that they do not produce a significant penumbra region in Xenon gas. As such, the scintillation time response for these events is similar to that of high-energy gamma rays. Other results of the present work include: The amount of energy deposited in the gas needed to produce a scintillation photon was measured for gamma rays and was found to be in agreement with results from other experiments. Low-energy gamma rays appeared to produce more scintillation photons for an equal amount of energy deposited than high-energy gamma rays. The decay of the singlet and triplet molecular states of xenon was observed and the lifetimes of these states were measured. The singlet state lifetime was found to be independent of pressure while the triplet state lifetime was dependent on pressure. The lifetimes were measured and compared to previous results. A better understanding of the ionization, recombination, and scintillation processes of gaseous Xenon was achieved. Argon gas has been proposed as an alternative to Xenon gas for use in a high-pressure gas scintillation detector due to its lower mass and its property of forming a core ionization region that is much less dense than the core region of xenon. This substitution may allow for a reliable discrimination characteristic to be developed.
