Recent developments
There have been developed three experimental high-gradient stand-separators of a wet and dry cleaning, including two ones with superconductor magnetic systems of induction 7 and 9 Tl to conduct technological tests of magnetic separation of weak-magnetic ores, placers, non-metallic materials, coal products and technogenic wastes.
There has been developed a draft of a high-gradient cryomagnetic separator for a dry slack fuel cleaning of the capacity up to 30 t/h.
There have been worked out engineering solutions, developed and tested an experimental model of an apparatus of a protecting disconnection. By its basic characteristics (time of operation and a short-time current loss to ground) the apparatus surpasses the existing protecting apparatuses not less than two times.
There have been developed and manufactured uniform stabilized sources with an automatic control of a superconducting switch to feed superconducting magnetic systems of a long-time instability of the output current up to 3·10-6.
There has been developed and introduced a number of fastacting micro-processor controllers to automate research experiments and create an ASCTP in industry.
There have been developed high-performance (with a measurement accuracy of 1 mm) economical digital sensors of the liquid helium level with a long-term memory system to serve cryogenic complexes.
There have been developed high-stable heterodyne two-channel bridges for EPR spectrometer of a 2-millimeter wave band with a maximum total capacity of both channels not less than 120 mWts.
There have been developed and introduced high-performance low-temperature chambers with waveguides and resonators for EPR-samples of central frequency 130 GHz, of a good quality more than 1000 and a communication parameter not less than 3.
There has been developed a number of high-stable of control and feed systems for vacuum generators of a microwave radiation (klystrons, backward-wave tube, diffraction-radiation oscillator, traveling-wave tube) with the system of automatic frequency adjustment by external discriminators.
