This grant funds R&D toward a portable cryogenic cooler                    for radiation detectors.  The cooler would weigh less than 10                   kg complete with a one week supply of cryogen, be self                          regulating in cryogen consumption to provide rapid cool down or                 response to transient demands while maintaining minimum                         consumption during steady state operation, require no                           electrical power, and have no critical moving parts which                       could pose reliability or maintenance problems.  The liquid                     carbon dioxide used for the expansion cycle can provide an                      operating temperature below minus 75 Celsius and should have an                 essentially infinite shelf life.  The R&D will be focussed on                   achieving good temperature stability and on minimizing                          microphonic noise in the associated high resolution Si X-Ray                    Detector.
