From Fermilab Today: “LBNE builds 35-ton prototype cryostat”

Fermilab continues to be a great source of strength in the U.S. Basic Research Community.

The LBNE far detector will require a cryostat to hold between 5,000 and 17,000 tons of liquid argon at 89 K – a significantly larger volume than any existing liquid-argon detector. The LBNE project team is currently constructing a 35-ton-capacity prototype cryostat at PPD’s PC-4 facility with the primary purpose of verifying that the high purity levels achieved last year in the Liquid Argon Purity Demonstrator, LAPD, are reproducible in a non-evacuated cryostat of the type planned for the LBNE detector.”
