As of today you can see and download the latest print issue of symmetry. This issue looks at many of the varied uses of accelerators in society. Although accelerators were typically created for basic physics research, they are key components of many medical and industrial applications now.
Students from 17 African countries came together for the rare opportunity to learn about particle physics this month. Some African students have earned advanced science degrees but are looking for the specialized training in particle physics and its associated applications not usually offered on their own continent. The first African School of Fundamental Physics and its Applications in Stellenbosch, South Africa, provided that training and financially supported some African students.

: logbook : solar neutrinos Logbook courtesy of Ray Davis Click on image for larger version . Deep in the Homestake Gold Mine in Lead , South Dakota , during the early 1970s , Ray Davis monitored a 100,000-gallon tank of perchloroethylene , a chlorine-rich dry-cleaning chemical . The experiment was designed to detect solar neutrinos , using the theory that an incoming neutrino would produce radioactive argon by interacting with a chlorine nucleus . Davis was successful , but detected just one-third of the expected number . This solar neutrino puzzle inspired a series of experiments that eventually confirmed neutrinos change flavors . For his work , Davis won the 2002 Nobel Prize in Physics . This page from his notebook captures a piece of that work . Davis discusses the tank cars

Jr and John N . Bahcall in the late 1960s . Its purpose was to collect and count neutrinos emitted by nuclear fusion taking place in the Sun Bahcall did the theoretical calculations and Davis designed the experiment . After Bahcall calculated the rate at which the detector should capture neutrinos , Davis's experiment turned up only one third of this figure . The experiment was the first to successfully detect and count solar neutrinos , and the discrepancy in results essentially created the solar neutrino problem The experiment

See all those steps in the graph red and blue lines Each little step is one bunch being added , and each big” step is 4 bunches being added . So if you count the steps yourself you should get a total bunch count of 25 in each beam . The red and blue lines correspond to the left-hand y-axis showing .

Today at the International Conference on High Energy Physics in Paris , the CMS and ATLAS experiments presented their first top quark candidates .
