SSC Cryogenic Plant Assessment for Fermilab's SRF R&D Facility at the New Muon Lab

Major components of the SSC laboratory's MTL helium refrigerator are in storage in the old ZGS Hall at Argonne National Laboratory.  Fermilab has the opportunity to obtain these plant components.  This website provides links to various documents about the SSC cryogenic plant and the suitability of that plant for use as the helium refrigerator for a superconducting RF R&D facility at the New Muon Lab at Fermilab.

"Design Verification and Acceptance Tests of the ASST-A Helium Refrigeration System," by V. Ganni and T. V. V. R. Apparao, Advances in Cryogenic Engineering, Vol 39A, pp. 779 - 787.  This paper describes tests of an essentially identical refrigerator to the one in storage at ANL.

Cryogenic plant cost estimate for a 60 W at 2 K, 105 W at 4 K, 820 W at 80 K system from a 2002 study by Theilacker and Klebaner (PDF file, 336 KB)
    This PDF file contains a few slides describing a cost estimate for a High Brightness Photo Injector (HBPI) system, an earlier version of the SMTF concept.

SRF system and SSC plant carnot analysis spreadsheet by Tom Peterson (16 May 05, Excel file, 54 KB)
    This spreadsheet uses some of the capacity and efficiency  information from Rao's spreadsheets to look at the SSC cryoplant capacity for various configurations with 2 K, 4 K and 40 - 80 K loads taken in proportion to those predicted.

Summary document -- this MS Word document contains a summary of information from the above listed spreadsheets for the committee and may be viewed as an early draft of an assessment document.  (18 May 05, MS Word, 6.2 MB)
