Long-Baseline Neutrino Facility

From The Wall Street Journal, July 21, 2017: Scientists celebrated the launch of an improbable physics experiment that will shoot subatomic particles through 800 miles of rock and dirt to study some fundamental cosmic riddles. [subscription required]

From Science, July 21, 2017: To build the modular detector, workers have to carve out massive caverns 1,480 meters underground, haul out stone that weighs as much as a dozen aircraft carries, and truck in millions of liters of frigid liquid argon. On July 21, officials gathered deep underground to turn the first few shovels of stone.

Sometimes, you can work on things for a long time, and it’s hard to measure progress. But there are other times when, suddenly, everything falls into place, and things happen very quickly!

The LBNF/DUNE team has had two main focus areas: gaining the approvals necessary to start early construction at the project’s far site at Sanford Lab in 2017 and prototyping the various systems that will eventually be scaled up and installed in DUNE’s massive underground neutrino detector.
