The Heisenberg Uncertainty Principle
... The Heisenberg Uncertainty Principle The Heisenberg uncertainty principle states that it is impossible to know both the momentum and the position of a particle at the same time. This limitation is critical when dealing with small particles such as electrons. But it does not matter for ordinary- ...

... A strange quark (s) was also required. And then a fourth quark called the charmed quark (c) was proposed to explain some additional discrepancies in the lifetimes of some of the known particles. A new quantum number called charm C was introduced so that the new quark would have C = +1 while its anti ...

Overview Acceleration with RF fields Bunches Phase
... A particle enters the cavity from the left. For acceleration, it needs to have the correct phase in the electric field. Assume that particle 1 travels at time t0 = 0 ns through cavity 1 – it will be accelerated by 1 MV. A particle that travels through the cavity at another time will be accelerated l ...

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.
