Materials for Optical Cryocoolers
Vibration free cooling of detectors to cryogenic temperatures is critical for many terrestrial, airborne, and space based instruments. Cooling of solids by anti Stokes fluorescence is an emerging refrigeration technology that is inherently vibration free and compact, and enables cooling of small loads to cryogenic temperatures. In this Highlight, advances in laser cooling of solids are discusse...
متن کاملCryocoolers for Microsatellite Military Applications
Space qualified cryocoolers have been extensively developed for large military and commercial satellite electro-optical (EO) infrared (IR) missions, but not so for microsatellites due to the complexity of the thermodynamics and fluid mechanics of the mechanical refrigeration system. The trend in military responsive space programs is leaning towards microsatellites that are cheaper and faster to...
متن کاملCryogenic design of a high-T, SQUID-based heart scanner cooled by small Stirling cryocoolers
A heart scanner based on high-T, SQUIDS is currently under development at the University of Twente. It is intended to be used in standard clinical environments without a magnetically shielded room. In order to make the application simple to use, the SQUIDS will be cooled by small cryocoolers, thus realizing a turnkey apparatus. The aimed field resolution is 50 ffRMs HZ-‘/~ in a measuring band o...
متن کاملTreatment of small scale gold mining wastewater using pilot-scale sedimentation and Cocopeat filter bed system
The use of amalgamation process to recover gold from mined ores by the small-scale gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies. In this study, a field-scale filter bed system was constructed to treat heavy metal metal-laden wastewater collected from small-scale gold mining site in Paracale, Camarines No...
متن کاملGIS-Based Small-Scale Hydropower Resources Assessment in Kurdistan - Iran
The industry development and the life standards increment have caused the human feels more easement, but it also has caused an increase of energy consumption, environmental pollution and the large volume of greenhouse gases emission. Those changes make the researchers to find out the alternative energy sources such as renewable energies. The most prominent and the oldest source of clean and re...
