The continuing LH2 R & D by the MuCool group, conducted by Illinois Consortium for Accelerator Research (ICAR) institutions (NIU, IIT and UIUC), the University of Mississippi, Oxford University and Fermilab, are summarized here, including results for the first hydrogen tests of an absorber prototype from Osaka University and KEK cooled by internal convection at the newly constructed FNAL MuCool Test Area (MTA). The program includes designs for the high-powered test of an absorber prototype (external heat exchange) at the MTA which are nearing completion to be installed by fall 2005, an alternative absorber design (internal heat exchange) being finalized for the approved cooling experiment (MICE) at Rutherford-Appleton Laboratory, and a novel idea for gaseous hydrogen absorbers being developed at Fermilab for a high powered test at the MTA in 2006.
