Moving Parts

A very simple effect makes it possible to construct very low temperature refrigerators without the use of low temperature moving parts or the Joule-Thomson effect. The effect, which occurs in many places and is frequently ignored, is described in detail, along with means for using it to build refrigerators capable of achieving low temperatures. A description of experimental models and test results is also included. A temperature 218 deg F below room temperature has been achieved.

HFO and HClO (fluorosyl and chlorosyl hydrides) and isomeric molecules HOF and HOCl (hypofluorous and hypochlorous acids) have been studied theoretically. On the basis of nonempiracal quantum chemical calculations (MP2, MP4 and CCD/6-311G**) geometry, energy and vibrational characteristics are analyzed and it is concluded that there is a poor chance to observe formation of HFO. Possibly, bombardment of HF in a solid matrix by 16O could lead at very low temperature to HFO.

A split-drain MAGFET has been designed for detecting magnetic fields at very low temperature. In this design a key parameter is the Hall angle, which indicates the current line deviation due to the Lorentz force acting on the charge carriers. It is well known that reducing the work temperature the carrier mobility increases, therefore an increase in carrier deflection is expected. As a consequence the split-drain MAGFET is able to detect magnetic fields below 1mT at 77K with low power consumption. Experimental results of a wide temperature range (20K< T
