A -- Portable Ge Radiation Spectrometer

LAWRENCE LIVERMORE NATIONAL LABORATORY SEEKS PARTNERSHIPS WITH INDUSTRY TO COMMERCIALIZE LLNL'S PORTABLE GE RADIATION SPECTROMETER. Announcement: Lawrence Livermore National Laboratory (LLNL), operated by the University of California under contract with the U.S. Department of Energy (DOE), is seeking one or more industrial partners to commercialize LLNL's portable Ge gamma-ray spectrometer developed jointly by LLNL and Lawrence Berkeley National Laboratory. The spectrometer contains an electromechanically cooled high purity encapsulated Ge detector that requires only electrical power to maintain the required operating temperature. Operation, including cool down, does not require the use of liquid nitrogen. The unit includes an inner radiation shield around the detector cooled by use of a Peltier thermoelectric cooler. The inner shield reduces the radiative load on the detector by approximately a factor or two, enhancing the portability, light-weight, and battery power usage for a mechanically cooled Ge spectrometer. The inner shield can also be used with detectors cooled conventionally with liquid nitrogen. A prototype spectrometer has been fabricated and is undergoing laboratory testing at LLNL. The unit has been operating since June 1998. The prototype weighs approximately 8 lbs, and draws 10 watts DC at input of the spectrometer. Note: THIS IS NOT A PROCUREMENT. Companies interested in commercializing LLNL's Portable gamma-ray spectrometer with actively driven thermal radiation shield should provide a written statement of interest including a commercialization plan and a description of corporate capabilities relevant to commercializing the technology. Written responses should be directed to: Lawrence Livermore National Laboratory Industrial Partnerships and Commercialization P.O. Box 808, L-795 Livermore, CA 94551-0808 Attention: FBO02-009-296. Please provide your written statement within thirty (30) days from the date this announcement is published to ensure consideration of your interest in LLNL's Portable Ge Radiations Spectrometer.
