Download or read book Backgrounds in XENON1T written by P. A. Breur and published by . This book was released on 2019 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are missing 85% of the matter in our Universe. This simple statement motivates thousands of physicists around the world to search for and explain dark matter. The first observations suggesting the existence of more non-luminous (e.g., dark matter and neutrinos) than luminous matter (e.g., stars, planets and gas) are now about 100 years old. The XENON1T experiment searches for a specific Dark Matter particle candidate, namely the weakly interacting massive particle (WIMP) with a liquid xenon target in an ultra-low background detector. XENON1T, located at the Laboratori Nazionali del Gran Sasso in Italy, uses 3.2 t of xenon as target material, which is purified and cooled continuously during operation. 248 light detectors are used to measure every particle interaction. To determine if dark matter interactions are found we compare the number of light flashes seen with the number we expect from Monte Carlo simulations. To have a chance of measuring WIMPs scattering off xenon nuclei, XENON1T was designed and built as an ultra-low background experiment. Monte Carlo simulations show that the main background component in the low energy region is from (naturally occurring) radon. This thesis starts with understanding the process of signal reconstruction and data selection in XENON1T to show its amazing performance. The second part is dedicated to determining the concentration and spatial distribution of the main background component. The last part presents the new, and most stringent, constraints on WIMPs in the space of mass versus cross-section. XENON1T is now proudly world leading in finding nothing.
Book Synopsis The Light Response of the XENON100 Time Projection Chamber and the Measurements of the Optical Parameters with the Xenon Scintillation Light by : Bin Choi

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A similar but a revised setup was built later at the University of Muenster in Germany for measuring the reflectivity of the PTFE (Chapter 5). These measurements are important for a deeper understanding of XENON100 and the next phase of the program with a XENON1T as well as for other liquid xenon experiments. Chapter 6 explains the details of the energy scale derived from the measurement of the light signals in XENON100 and the cuts used for the analysis, which has led to the most recent scientific results from this experiments. In 2012, the XENON100 dark matter results from 225 live days set the most stringent limit on the spin-independent elastic WIMP- nucleon interaction cross section for WIMP masses above 8 GeV/c 2, with a minimum of 2 × 10and minus;45 cm 2 at 55 GeV/c 2 and 90% confidence level. With this result XENON100 continues to be the leading experiment in the direct search for dark matter.

Book excerpt: "One of the most promising detector technologies to directly detect weakly interacting massive particle (WIMP) dark matter are time projection chambers (TPCs) filled with dual-phase (liquid and gaseous) xenon. The hypothetical WIMP could scatter with atoms in the liquid and the transferred recoil energy would lead to a prompt light signal (S1) and, after a drift time of ionisation electrons into the gas phase, to a secondary signal (S2). Only a detection of a dark matter particle interaction can provide evidence beyond doubt for its existence and could potentially solve a puzzle that combines astroparticle physics and cosmology. To date, even the most sensitive detectors (filled with more than 100 kg of liquid xenon) could not produce indisputable proof of dark matter. In order to improve the sensitivity of future dual-phase xenon TPCs this thesis investigated the GridPix detector as an alternative for the detection of the S2 signal. Unlike the typically used photomultiplier tubes, GridPix offers a lower radioactive content. This could reduce the intrinsic background of the TPC, hence making it more sensitive to small energy deposits. However, the studies showed that GridPix does not operate stably enough at the challenging conditions of high-purity, low-temperature gas. To test other detector technologies as well as to study xenon properties and data acquisition techniques, a small-scale dual-phase xenon TPC was built and commissioned at Nikhef: XAMS, a xenon facility at Amsterdam. Calibration measurements showed the basic functioning of the TPC and led to improvements that make XAMS a valuable testing ground for future dark matter search experiments."--Samenvatting auteur.

Book Synopsis Fluoropolymers 2 by : Gareth G. Hougham
Download or read book Fluoropolymers 2 written by Gareth G. Hougham and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fluorine atom, by virtue of its electronegativity, size, and bond strength with carbon, can be used to create compounds with remarkable properties. Small molecules containing fluorine have many positive impacts on everyday life of which blood substitutes, pharmaceuticals, and surface modifiers are only a few examples. Fluoropolymers, too, while traditionally associated with extreme high performance applications have found their way into our homes, our clothing, and even our language. A recent American president was often likened to the tribology of PTFE. Since the serendipitous discovery of Teflon at the DuPont Jackson Laboratory in 1938, fluoropolymers have grown steadily in technological and marketplace importance. New synthetic fluorine chemistry, new processes, and new apprecia tion of the mechanisms by which fluorine imparts exceptional properties all contribute to accelerating growth in fluoropolymers. There are many stories of harrowing close calls in the fluorine chemistry lab, especially from the early years, and synthetic challenges at times remain daunting. But, fortunately, modem techniques and facilities have enabled significant strides toward taming both the hazards and synthetic uncertainties, In contrast to past environmental problems associated with fluorocarbon refrigerants, the exceptional properties of fluorine in polymers have great environmental value. Some fluoropolymers are enabling green technologies such as hydrogen fuel cells for automobiles and oxygen selective membranes for cleaner diesel combustion.
Book Synopsis Measurements of Neutrino Mass by : F. Ferroni
Download or read book Measurements of Neutrino Mass written by F. Ferroni and published by IOS Press. This book was released on 2009-09-29 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a valuable insight into various aspects of the ongoing work directed at measuring neutrino mass. It took twenty years to refute the assertions of Bethe and Peierls that neutrinos were not observable, but it has since been realised that much can be learnt from these particles. The moral is, as Fiorini argues here, that the study of neutrinos was and remains demanding but rewarding. Subjects addressed in this volume include; clarifying the meaning of the Klapdor-Kleingrothaus results, probing the Majorana nature of neutrinos, observing lepton number violating effects for the first time, studying the end point of the spectrum in the search for neutrino masses and speculating whether it is possible to measure neutrino masses in cosmology. Lectures are enriched with rich historical overviews and valuable introductory material. Attention is also given to theoretical topics such as the evolution of the concept of mass in particle physics, a status report on neutrino oscillations and current discussion on neutrino masses. The reader is further reminded that neutrino masses may also have some bearing on the very origin of the matter among us, and have many deep links with other important lines of current physics research.
