argon

CERN’s ProtoDUNE has entered a pivotal stage: the filling of one of its two particle detectors with liquid argon. The liquid argon will provide a clean environment for precise measurements in neutrino interactions and allow scientists to detect and study neutrino interactions.

From the Black Hills Pioneer, November 12, 2022: How do you fit a 3.5 ton piece of steel that is 6 meters long and 2.5 meters wide safely down the Ross Shaft at Sanford Lab? Justin Evans, a professor at Manchester University, explains how the anode plane assembly traveled from the UK to Lead, SD and its roles as a key component to the DUNE experiment.

For the first time, physicists extracted the detailed “energy-dependent neutrino-argon interaction cross section,” a key value for studying how neutrinos change their flavor.

From the California News Times, June 9, 2021: There is a new robotics project at Fermilab called Argonaut and its mission is to sail into a sea of liquid argon kept at minus 193 degrees Celsius to monitor the condition inside the ultra-low temperature particle detector.

From Laboratory Equipment, May 31, 2021: Fermilab engineer Bill Pellico wondered if it would be possible to make the interior cameras movable using liquid argon detectors to inspect the inside of detectors.

From Physics World, June 12, 2019: Physics World posts a video recorded inside the ProtoDUNE neutrino detector by the particle physicist and vocalist Anastasia Basharina-Freshville, who sing-explains why the noble gas is used to detect the elusive particles.

The Deep Underground Neutrino Experiment is advancing technology commonly used in dark matter experiments—and scaling it up to record-breaking sizes.
