Available in PDF, EPUB and Kindle. Book excerpt: It is of general interest to make the mesons artificially produced in the 184-inch cyclotron available for general experiments outside the tank. Thus far only photographic techniques have been used in conjunction with the Berkeley meson work. By bringing the beam outside the tank it is hoped that cloud chamber, and possibly counter methods, may be used in meson studies. In addition, the measurement of the lifetime of the [pi] meson appears possible if long meson trajectories are obtained. The method discussed here accomplishes the removal of the mesons from the cyclotron tank by allowing the mesons produced in a thin target struck by the 380 Mev alpha particle beam to enter a region of very weak magnetic field which permits them to leave the tank along a path of weak curvature. The technical problem involved here is, therefore, to produce a magnetic shield which reduces the field of the cyclotron from about 14,000 gauss to about 1,000 gauss, and to place this shield within a very short distance of the circulating beam without disturbing the dynamics of the beam itself.
Download or read book Positive Mesons Produced by the 184 inch Berekely Cyclotron written by John Burfening and published by . This book was released on 1949 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Positive mesons produced by 380 Mev alpha-particles in the 184-inch Berkeley cyclotron have been detected by means of photographic plates. The experimental arrangement is similar to that used for detecting negative mesons except that the plates are placed in a position to receive positive instead of negative particles from the target. Heavy positive mesons are observed to decay into secondary mesons in the manner described by Lattes, Occhialini and Powell. Relative numbers of positive aid negative me sons coming from a target are found by placing plates symmetrically on opposite sides of the target. Preliminary results indicate that for a 1/16 inch carbon target there are about one fourth as many heavy positive mesons as heavy negative ones for meson energies of 2-3 Mev in the laboratory system.

Available in PDF, EPUB and Kindle. Book excerpt: Thisbookgrewoutof anongoing e?orttomodernizeColgate University’s three-term,introductory,calculus-level physicscourse. Thebookisforthe ?rst term of this course and is intended to help ?rst-year college students make a good transition from high-school physics to university physics. Thebookconcentrates onthephysicsthatexplainswhywebelievethat atoms exist and have the properties we ascribe to them. This story line, which motivates much of our professional research, has helped us limit the material presented to a more humane and more realistic amount than is presented in many beginning university physics courses. The theme of atoms also supports the presentation of more non-Newtonian topics and ideas than is customary in the ?rst term of calculus-level physics. We think it is important and desirable to introduce students sooner than usual to some of the major ideas that shape contemporary physicists’ views of the nature and behavior of matter. Here in the second decade of the twenty-?rst century such a goal seems particularly appropriate. The quantum nature of atoms and light and the mysteries associated with quantum behavior clearly interest our students. By adding and - phasizing more modern content, we seek not only to present some of the physics that engages contemporary physicists but also to attract students to take more physics. Only a few of our beginning physics students come to us sharply focused on physics or astronomy. Nearly all of them, h- ever, have taken physics in high school and found it interesting.

This book was released on 2018-03-21 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of modern particle physics accessible to anyone with a true passion for wanting to know how the universe works. We are introduced to the known particles of the world we live in. An elegant explanation of quantum mechanics and relativity paves the way for an understanding of the laws that govern particle physics. These laws are put into action in the world of accelerators, colliders and detectors found at institutions such as CERN and Fermilab that are in the forefront of technical innovation. Real world and theory meet using Feynman diagrams to solve the problems of infinities and deduce the need for the Higgs boson. Facts and Mysteries in Elementary Particle Physics offers an incredible insight from an eyewitness and participant in some of the greatest discoveries in 20th century science. From Einstein's theory of relativity to the spectacular discovery of the Higgs particle, this book will fascinate and educate anyone interested in the world of quarks, leptons and gauge theories. This book also contains many thumbnail sketches of particle physics personalities, including contemporaries as seen through the eyes of the author. Illustrated with pictures, these candid sketches present rare, perceptive views of the characters that populate the field.

In addition to the story of quarks and leptons, which are regarded as well-accepted fact, the author (who is a leading researcher at one of the world's highest energy particle physics laboratories) also discusses mysteries at both the experimental and theoretical frontiers, before tying it all together with the exciting field of cosmology and indeed the birth of the universe itself.
Download or read book From Ultra Rays to Astroparticles written by Brigitte Falkenburg and published by Springer Science & Business Media. This book was released on 2012-12-30 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope of the book is to give an overview of the history of astroparticle physics, starting with the discovery of cosmic rays (Victor Hess, 1912) and its background (X-ray, radioactivity). The book focusses on the ways in which physics changes in the course of this history. The following changes run parallel, overlap, and/or interact: - Discovery of effects like X-rays, radioactivity, cosmic rays, new particles but also progress through non-discoveries (monopoles) etc. - The change of the description of nature in physics, as consequence of new theoretical questions at the beginning of the 20th century, giving rise to quantum physics, relativity, etc. - The change of experimental methods, cooperations, disciplinary divisions. With regard to the latter change, a main topic of the book is to make the specific multi-diciplinary features of astroparticle physics clear.
