Chapter 30 – Particle Physics
... particles have nonzero masses. Quarks and leptons have weak charge and so feel the weak force. The weak interaction allows one flavor of quark to change into any other flavor of quark. In beta-‐‑minus decay, a neutron changes into a proton. This occurs ...

... QUICK QUIZ 27.2 A photon of energy E0 strikes a free electron, with the scattered photon of energy E moving in the direction opposite that of the incident photon. In this Compton effect interaction, the resulting kinetic energy of the electron is (a) E0 , (b) E , (c) E0 E , (d) E0 + E , (e) none ...

6.5 Synchrotron radiation and damping
... The vertical damping partition number is usually unchanged as the vertical dispersion is zero in storage rings that are built in one (horizontal) plane. The amount of damping can be repartitioned between the horizontal and energy-time oscillations by altering the value of the D constant [4]. This ca ...

DESY
The Deutsches Elektronen-Synchrotron (english German Electron Synchrotron) commonly referred to by the abbreviation DESY, is a national research center in Germany that operates particle accelerators used to investigate the structure of matter. It conducts a broad spectrum of inter-disciplinary scientific research in three main areas: particle and high energy physics; photon science; and the development, construction and operation of particle accelerators. Its name refers to its first project, an electron synchrotron. DESY is publicly financed by the Federal Republic of Germany, the States of Germany, and the German Research Foundation (DFG). DESY is a member of the Helmholtz Association and operates at sites in Hamburg and Zeuthen.
