Focusing an antimatter beam with matter

An experiment at the Stanford Linear Accelerator Center has recently focused positron beams by means of a plasma lens. This is the first time this process has been observed.

More collisions ahead for HERA

The unique HERA electron-proton collider at DESY, Hamburg, achieved record performance in 2000 before being shut down for nine months of "lumi upgrade".

RHIC starts producing data

After achieving first collisions of gold ion beams on the night of 12 June, the gleaming new Relativistic Heavy Ion Collider (RHIC) facility at Brookhaven wasted no time in ramping up in energy and i...

B-factories give first results: PEP-II at SLAC…

The PEP-II asymmetric B-factory at the Stanford Linear Accelerator Center (SLAC) continues to exceed expectations, having nearly reached its design performance after only a year of operations.

…and Belle at KEKB, Japan

The Belle experiment at the KEKB asymmetric-energy electron-positron B-meson factory recently completed a successful first year of operation.

LEP hints at Higgs effect

After commencing 2000 operations in fine style, CERN's flagship machine, the LEP electron-positron collider, has been regularly delivering experiments with beams of 103 GeV or more.

CEBAF reaches 150% of its design energy

Jefferson Laboratory's CEBAF accelerator, which was originally designed to provide 4 GeV continuous-wave electron beams, has demonstrated 6 GeV continuous-wave operation.

KEK laboratory demonstrates for the first time feature

KEK laboratory demonstrates fixed-field synchrotron

The Japanese KEK laboratory has for the first time demonstrated an alternative method of accelerating protons to high energy - the fixed-field, alternating gradient (FFAG) synchrotron.

Proton collaboration is under way in Japan

In Japan the KEK high-energy physics laboratory and the Japan Atomic Energy Research Institute are working together to finalize preparations for a major new high-intensity proton source, with applic...
