CDF achieves most precise measurement of the top quark mass
The CDF collaboration at DOE’s Fermi National Accelerator Laboratory has achieved the world’s most precise measurement of the mass of the top quark, the heaviest elementary particle ever observed. Using the Collider Detector at Fermilab, a 6,000-ton instrument that records particles emerging from proton-antiproton collisions, scientists determined the top quark mass to be 172.64 GeV/c2, almost as heavy as a gold atom. -
Simultaneous nanoscale imaging of surface and bulk atoms
Scientists at DOE's Brookhaven Lab have demonstrated a new scanning electron microscope capable of selectively imaging single atoms on the top surface of a specimen while a second, simultaneous signal shows atoms throughout the sample’s depth. -
Common industrial catalyst sports rafts of platinum
Scientists in the Institute for Interfacial Catalysis at DOE’s Pacific Northwest National Laboratory and Oak Ridge National Laboratory analyzed the common industrial catalyst aluminum oxide-supported platinum. -

LANL Radioactive Waste Facility Torn to Shreds, Crowds Applaud
A Los Alamos National Laboratory crew on Sept. 30 began demolishing the first containment dome at the DOE lab’s largest and only remaining active disposal area.
The 38-foot high, 345-foot-long facility known as “Dome 226” is made of fabric over aluminum ribbing.
