Title: Magnetic flux measurement circuit with super-conductive quantum interference detector - has detector coupled to electrical oscillation circuit beyond which evaluation electronics are connected
Inventor: ZHANG YI DR
IPC: G01R33/035
Filed: 1991-06-17
Abstract: The circuit incorporates a super-conductive QUANTUM - interference detector, (SQUID), with a super-conductive ring and Josephson element. Beyond the oscillation circuit is connected an undamping circuit with adjustable positive back-coupling. For beta(o) 1 for detection of the measurement signal a frequency demodulator (RM) is provided. The undamping circuit takes the place of the otherwise customary additional Hf oscillator. Via the undamping there are two effects with the noise spectra, viz. a resonance frequency displacement and an alteration in the quality of the oscillation circuit due to a variation in external flux. ADVANTAGE - Overcomes quality of oscillation circuit disadvantages which can hardly be enhanced by alteration of coil.
