ICARUS neutrino detector installed in new Fermilab home

For four years, three laboratories on two continents have prepared the ICARUS particle detector to capture the interactions of mysterious particles called neutrinos at the U.S. Department of Energy's Fermi National Accelerator ...

Scientists investigating mysterious dark matter

University of Houston scientists are helping to develop a technology that could hold the key to unraveling one of the great mysteries of science: what constitutes dark matter? Scientists believe dark matter makes up 85 percent ...

Physicists contribute to dark matter detector success

In researchers' quest for evidence of dark matter, physicist Andrea Pocar of the University of Massachusetts Amherst and his students have played an important role in designing and building a key part of the argon-based DarkSide-50 ...

How to produce the purest argon ever

CERN is taking part in a project, called ARIA, for the construction of a 350-metre-tall distillation tower that will be used to purify liquid argon (LAr) for scientific and, in a second phase, medical use.

VENu makes it possible to watch a neutrino hunter at work

What happens when tiny, invisible particles called neutrinos are sent hurtling through a tank of liquid argon? For most of the neutrinos, not much. They'll pass through the argon unscathed. But other neutrinos will collide ...

LArIAT upgrade will test DUNE design

In particle physics, the difference of a millimeter or two can make or break the experiment. In March, the LArIAT experiment began a proof-of-concept test to make sure the planned Deep Underground Neutrino Experiment (DUNE) ...

Argon is not the 'dope' for metallic hydrogen

Hydrogen is both the simplest and the most-abundant element in the universe, so studying it can teach scientists about the essence of matter. And yet there are still many hydrogen secrets to unlock, including how best to ...

New wings give ICARUS flight for second neutrino hunt

It's a big shining box, 4 metres high, 20 metres long: this magnificent detector arrived at CERN 16 months ago and since then it is undergoing a complete refurbishing. ICARUS, a 760-ton detector filled with liquid argon (LAr) ...
