Ultrapure copper for an ultrasensitive dark matter detector

In February and March, three batches of copper plates arrived at Fermilab and were rushed into storage 100 meters underground. The copper had been mined in Finland, rolled into plates in Germany and shipped across land and ...

Scientists repurpose MRI magnet for new discoveries

A limiting factor in modern physics experiments is the precision at which scientists can measure important values, such as the magnetic field within a detector. Scientists at the U.S. Department of Energy's (DOE) Argonne ...

Density fluctuations in amorphous silicon discovered

For the first time, a team at HZB has identified the atomic substructure of amorphous silicon with a resolution of 0.8 nanometres using X-ray and neutron scattering at BESSY II and BER II. Such a-Si:H thin films have been ...

Bumper crop of black holes in new gravitational wave paper

Only a few years ago, scientists the world over celebrated as the first-ever gravitational waves were detected—confirming a long-held scientific theory and opening up an entirely new field of research.
