Accelerator project digs itself into a hole

Building a scientific data grid with DiGS.

We provide an insight into the challenge of building and supporting a scientific data infrastructure with reference to our experience working with scientists from computational particle physics and molecular biology. We illustrate how, with modern high-performance computing resources, even small scientific groups can generate huge volumes (petabytes) of valuable scientific data and explain how ...

A hole accelerator for InGaN/GaN light-emitting diodes

Falling into a black hole

String theory tells us that quantum gravity has a dual description as a field theory (without gravity). We use the field theory dual to ask what happens to an object as it falls into the simplest black hole: the 2-charge extremal hole. In the field theory description the wavefunction of a particle is spread over a large number of ‘loops’, and the particle has a well-defined position in space on...

The Accelerator Production of Tritium Project

Tritium is essential for U.S. nuclear weapons to function, but because it is radioactive with a half-life of 12.3 years, the supply must be periodically replenished. Since the last production reactor stopped operating in 1988, tritium has been recovered from dismantled nuclear weapons. This process is possible only as long as many weapons are being retired and will not work indefinitely, thus r...

The Super-b Project Accelerator Status

The SuperB project is an international effort aiming at building in Italy a very high luminosity ee (10 cm sec) asymmetric collider at the Y(4S) energy in the CM. The accelerator design has been extensively studied and changed during the past year. The present design, based on the new collision scheme, with large Piwinski angle and the use of “crab waist” sextupoles already successfully tested ...
