Available in PDF, EPUB and Kindle. Book excerpt: A precision measurement of the anomalous g value, a{sub {mu}}=(g-2)/2, for the positive muon has been made using high intensity protons available at the Brookhaven AGS. The result based on the 1999 data a{sub {mu}}=11659202(14)(6) x 101° (1.3ppm) is in good agreement with previous measurements and has an error one third that of the combined previous data. The current theoretical value from the standard model is a{sub {mu}} (SM)=11659159.6(6.7) x 101° (0.57 ppm) and differ by over 2.5 standard deviation with experiment. Issues with reducing systematic errors and enhancing the injection and storage efficiencies are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Accelerators as research and industrial tools are increasingly becoming a key driver of the advances of a modern society. As accelerators and its science evolved to meet the ever-increasing needs of society, the field of accelerator physics has evolved and deepened over the past few decades, and many of its branches developed into special topics of research by their own rights. It is appropriate at this time to start accumulating this hard-earned expertise by the accelerator physics community. With this view, a selection of these special topics is presented in this volume, Special Topics in Accelerator Physics. Although not exhaustive, they are chosen to present accelerator physics as a diversified and exciting field and written based on the practicing and teaching experiences of the author accumulated over the past decades. The book is presented as an advanced textbook. The material on each topic has been intended to be self-contained. The reader is assumed to have a basic knowledge of accelerator physics to put the material in some context.

Book excerpt: The Muon (g-2) Experiment (E821) at Brookhaven National Laboratory (BNL) started data taking in 1997. The latest result a{sub {mu}} = 11659202(14)(6) x 10−1°, based on statistics of about 1 billion decays collected in 1999, is in good agreement with the previous measurement. With the precision of 1.3 ppm, the result, compared with the Standard Model evaluation a{sub {mu}}(SM) = 11659159.6(6.7) x 10−1°, shows a difference of a{sub {mu}}(exp)-a{sub {mu}}(SM) = 43(16) x 10−1°.
Download or read book Optimization of Muon Injection and Storage in the Fermilab G 2 Experiment written by Nathan Seth Froemming and published by . This book was released on 2018 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anomaly of the muon magnetic dipole moment, a[subscript mu] [triple bar] (g[subscript mu] -2)/2, is a sensitive probe into the Standard Model (SM) of particle physics because it can be calculated with high precision and also measured with high precision. Comparison of the experimental and theoretical values of a[subscript mu] therefore provides a stringent test of the completeness of the Standard Model, with any deviation suggesting the existence of new physics as a possible explanation. The most recent experimental determination of a[subscript mu] was performed by the E821 collaboration at Brookhaven National Laboratory (BNL) from 1997--2001, where a final precision of [delta]a[subscript mu]/a[subscript mu] = ±540 was achieved. The value of a[subscript mu] obtained by E821 presently differs from the SM prediction by 3.5--4.0 standard deviations, hinting strongly---albeit inconclusively---of the existence of new physics. The BNL experiment was limited by statistics. A next-generation experiment at Fermi National Accelerator Laboratory (Fermilab), which utilizes the same BNL storage-ring magnet with many significant upgrades, aims to measure a[subscript mu] to a final precision of 140ppb, thus helping to resolve the discrepancy between experiment and theory once and for all. The new Fermilab measurement of a[subscript mu] requires approximately ~20X the entire BNL dataset to be recorded and analyzed, a difficult task. Therefore, optimization of the muon injection efficiency, capture fraction, and stored-muon beam properties are critical requirements for completing the new measurement in a timely manner with the required precision. These topics are the subject of this thesis.

Download or read book History of CERN II written by A. Hermann and published by North Holland. This book was released on 1987 with total page 936 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first volume of the History of CERN (published in 1987) dealt with the launching of the European Organization for Nuclear Research covering the period 1949 to 1954. Volume II continues the history through to the mid-1960's, when it was decided to equip the laboratory with a second generation of accelerators and a new Director-General was nominated. It covers the building and the running of the laboratory during these dozen years, it studies the construction and exploitation of the 600 MeV Synchro-cyclotron and the 28 GeV Proton Synchrotron, it considers the setting up of the material and organizational infrastructure which made this possible, and it covers the reigns of four Director-Generals, Felix Bloch, Cornelis Bakker, John Adams and Victor Weisskopf. Three considerations are relevant to the treatment of the material in this volume. Firstly the political dimension, in the broad sense of the term, was no longer omnipresent as during the process of creation. Alongside it scientific and technical determinations were at work. The second consideration is that the institutional dimension was also inescapably present. Finally, there was no longer one dominant process in the organisation's life but several and it was no longer possible to tell just one story. The authors therefore decided to focus attention on various aspects of CERN's life. Part I attempts to describe the various aspects which together constitute the history of CERN and aims to offer a synchronic panorama year by year account of CERN's many activities. Part II deals primarily with technological achievements and scientific results and it includes the most technical chapters in the volume, chapters using as main sources publications in the open literature, internal reports, and minutes of specialized committees or of divisional meetings. Part III aims to define how the CERN ``system'' functioned, how this science-based organization worked, how it chose, planned and concretely realized its experimental programme on the shop-floor and how it identified the equipment it would need in the long term and organized its relations with the outside world, notably the political world. The concluding Part IV aims to bring out the specificity of CERN, to identify the ways in which it differed from other big science laboratories in the 1950's and 1960's, and to try to understand where its uniqueness and originality lay.

Download or read book From The Preshower To The New Technologies For Supercolliders written by Albrecht Wagner and published by World Scientific. This book was released on 2002-12-24 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the year 2000, the city of Bologna was the European Capital for Culture. For this reason, the University of Bologna and its Academy of Sciences, following the Gugliemo Marconi Centenary and the Luigi Galvani Bicentenary Celebrations, decided to call attention to the major achievements of their most distinguished members, in science and technology.This invaluable volume presents a series of inventions and technological developments, some thought of and directly implemented by Professor Antonino Zichichi, others suggested and developed under his leadership, all of them having contributed to the discovery of new particles and new phenomena in the field of subnuclear physics. The book was conceived by an eminent scientist, Professor Dr Björn H Wiik, Director of Germany's most prestigious physics laboratory, DESY (Hamburg). It would not be published were it not for Professor Dr Albrecht Wagner, Chairman of the DESY Board of Directors, and Dr Horst Wenninger from CERN (Geneva), the greatest European physics laboratory.
