Fermilab takes beneficial occupancy of the LArTF

Fermilab took beneficial occupancy of the Liquid-Argon Test Facility on May 15 from Whittaker Construction Company, contracted to construct the LArTF. A “punch list” of a few remaining items to complete was created, and Whittaker has been rapidly finishing those items. Now that beneficial occupancy is obtained, Fermilab has begun installing other items and equipment. One of the first items to be moved onto the LArTF site were two dewar vessels formerly used for liquid-nitrogen storage at the Central Helium Liquefier. As seen in this picture of the LArTF, the left dewar vessel will again be used for liquid-nitrogen storage, and the right vessel will be used for liquid-argon storage. The vessels fit perfectly on the tie-down bolts, which were part of the stands built by Whittaker.
