The Front End of the Spallation Neutron Source: Berkeley Lab sets the pace

A step closer to intense neutron beams

By producing 24 milliamps of negative hydrogen ions at an energy of 2.5 MeV from a unique radio-frequency quadrupole accelerator, Berkeley Lab scientists and engineers are on track and on target to completing the SNS Front-End System, the first major component of DOE's Spallation Neutron Source, which will provide the most intense neutron beams ever generated for research.

A BETR way to track pollutants

A collaboration among environmental scientists at Berkeley Lab and Ontario's Trent University provides a new way to track the spread of toxic waste through the air, water, and land in 24 regions of North America-- one of the first comprehensive cross-border computer models of contaminant "transport and fate."

Genome panoramas
Biologists and computer scientists have joined forces to create a powerful tool for comparing DNA sequences from two or three or even more organisms. VISTA is a fast way to spot sequence similarities -- or differences -- in everything from short requlatory sequences to single genes to entire genomes. And it's available on the web.

With Cryo3, a 10-pound, battery-powered radiation detector, DOE engineers are working to outsmart anyone trying to smuggle radioactive material into the country.

For the first time, researchers have seen what theorists have long suspected: granular separation of states in high-temperature superconductors.

Suspicious behavior of high-temperature superconductors set scientific detectives on the trail of granular superconductivity.
