This book was released on 2012 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis High Pressure Xenon Detectors for Rare Physics Searches by : Joshua Edward Renner
Download or read book High Pressure Xenon Detectors for Rare Physics Searches written by Joshua Edward Renner and published by . This book was released on 2014 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: High pressure xenon gas detectors have the potential to significantly contribute to searches for rare physics processes such as neutrinoless double beta (0[nu][beta][beta]) decay and interactions of dark matter with ordinary matter. We summarize the physics and implications of these two phenomena and discuss experimental developments conducted with an electroluminescent high pressure xenon time projection chamber (TPC). The detector was constructed as a prototype for the NEXT experiment - Neutrino Experiment with a Xenon TPC - and was intended to demonstrate an ability to detect electron recoils with an energy resolution sufficient for a strong neutrinoless double beta decay search. Using the low-gain ionization signal amplification process of electroluminescence, we are able to obtain an energy resolution of approximately 1% FWHM in the detection of 662 keV gamma rays. In addition, we demonstrate basic particle tracking capabilities using a silicon photomultiplier-based tracking plane, a technique also relevant to the NEXT approach in searching for 0[nu][beta][beta] decay. To investigate the possibility of a gaseous xenon dark matter detector, we also characterize the ionization and scintillation signals produced by nuclear recoils in the TPC and compare them to the corresponding signals produced by electron recoils. The nuclear recoils are produced using radioisotope neutron sources. Our measurements demonstrate the ability to discriminate between electron and nuclear recoils using the ratio of ionization to scintillation produced on an event-by-event basis and provide an estimate of the ionization and scintillation yields of nuclear recoils in gaseous xenon. We end with a discussion of the physical principles behind another approach to obtaining nearly-intrinsic energy resolution in a noble gas detector. This approach, called negative ion drift, consists of drifting negative ions produced by intentionally introducing impurities into a gaseous medium that capture ionization electrons. These negative ions are then counted individually by detaching and amplifying the electron they carry. We develop a basic formalism in an attempt to understand the ion drift and detachment processes that are critical to the implementation of this technique.

Book Synopsis Particle Detectors by : Hermann Kolanoski
Download or read book Particle Detectors written by Hermann Kolanoski and published by Oxford University Press. This book was released on 2020-06-30 with total page 949 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the fundamentals of particle detectors as well as their applications. Detector development is an important part of nuclear, particle and astroparticle physics, and through its applications in radiation imaging, it paves the way for advancements in the biomedical and materials sciences. Knowledge in detector physics is one of the required skills of an experimental physicist in these fields. The breadth of knowledge required for detector development comprises many areas of physics and technology, starting from interactions of particles with matter, gas- and solid-state physics, over charge transport and signal development, to elements of microelectronics. The book's aim is to describe the fundamentals of detectors and their different variants and implementations as clearly as possible and as deeply as needed for a thorough understanding. While this comprehensive opus contains all the materials taught in experimental particle physics lectures or modules addressing detector physics at the Master's level, it also goes well beyond these basic requirements. This is an essential text for students who want to deepen their knowledge in this field. It is also a highly useful guide for lecturers and scientists looking for a starting point for detector development work.

This book was released on 2006-02-23 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: TheFifthHEIDELBERGInternationalConferenceonDarkMatterinAst- and Particle Physics, DARK 2004, took place at Texas A&M University, College Station Texas, USA, October 3–9, 2004. It was, after Cape Town 2002, the second conference of this series held outside Germany. The earlier meetings, starting in 1996, were held in Heidelberg. Dark Matter is still one of the most exciting and central ?elds of ast- physics, particle physics and cosmology. The conference covered, as usual for this series, a large range of topics, theoretical and experimental. Theoretical talks covered SUSY/SUGRA phenomenology, which provides at present a preferred theoretical framework for the existence of cold dark matter. Also included were other possible explanations of dark matter such as SUSY Q balls, exciting New Symmetries, etc. The most important experiments in the underground search for cold and hot dark matter were presented. Talks describing the current experimental dark matter bounds, what might be obtained in the near future, and the reach of future large (i.e. one ton) detectors were given. The potential of future colliders to correlate accelerator physics with dark matter searches was also outlined. Thus the reader will be able to see the present status and future prospects in the search for dark matter. The exciting astronomical evidence for dark matter and corresponding observations concerning the Milky Way’s black hole, high-redshift clusters, wakes in dark matter halos were other important topics at the conference.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We report a demonstration of the scalability of optically transparent xenon in the solid phase for use as a particle detector above a kilogram scale. We employ a liquid nitrogen cooled cryostat combined with a xenon purification and chiller system to measure the scintillation light output and electron drift speed from both the solid and liquid phases of xenon. Scintillation light output from sealed radioactive sources is measured by a set of high quantum efficiency photomultiplier tubes suitable for cryogenic applications. We observed a reduced amount of photons in solid phase compared to that in liquid phase. We used a conventional time projection chamber system to measure the electron drift time in a kilogram of solid xenon and observed faster electron drift speed in the solid phase xenon compared to that in the liquid phase.
