"Cryo" was assembled during the 2005-06 summer...

First, a temporary cryo setup was created. The 3000 liter
Wessington dewars (at right) were moved out of the old cryo barn so that the permanent site could be backfilled (I).

 Looking the other way, here's the south dewar storage module moved out of the way. Upper right, the north section is staged next to the temporary cryo facility (PR). |
 Sections of the center module were shaken out (PR). |
 Here the south module has been placed in position, and the center module is being erected (RP). |
 Here the roof panels are being installed connecting these two units (RP). |
 The south 2/3 of the facility have been put together next to the BIF (I). |
 The assembled structure; this view shows how much fill was added to raise this building out of the "bowl." (BB). |
 The front view. The old cryo barn has been positioned to the left of the new structure; the BIF is at right (USAP), |
 Another view from the front. The center portion houses those Wessington dewars, the right portion houses the admin and mechanical space, as well as room for the LN2 plant, which might be moved here from MAPO (hmmm....). (JB) |
 A view from the BIF end of the complex (KJ). |
 A closer look (BB). |

Interior finish work continued through the winter...official occupancy happened in the summer of 2006-07.

Just what you wanted to know...but seriously, this new facility has meant that Pole has NOT run out of LHe in the 2005 or 2006 winters. |
