Low- and High-Tc Squids and Some Applications,he signal source. Typical dc SQUIDs operated at 4.2 K have a magnetic flux noise of 10. Φ. Hz., where Φ. is the flux quantum, corresponding to a magnetic noise energy of 10. JHz.. With the aid of a superconducting flux transformer the magnetic field noise can approach 1 fT Hz./.. High-T. dc SQUIDs f

Multichannel SQUID Biomagnetic Systems,8. Since the introduction of whole-cortex magnetoencephalography (MEG) systems in 1992, the number of installed channels has dramatically increased, and the magnetic evaluation of the human brain has been gradually finding its place in clinical work. MEG is presently the most important biomagnetic a

Applications of SQUID Magnetometers to Biomagnetism and Nondestructive Evaluation,s, liver, nerves, skeletal muscle, stomach, intestines, eyes, and other organs. The majority of the effort in the field has been by university and national-laboratory researchers and by small, high-technology companies, and has been directed towards the development and promotion of this technology.

MRI Magnets,entific or industrial research. However, it was not until the emergence of Magnetic Resonance Imaging (MRI) in the late 1970’s that a commercial application of superconductivity appeared that would take superconductivity out of the laboratory and into everyday use. The strong and stable magnetic fie
