Random Noise Considerations in the Design of Magnetic Film Sense Amplifiers
نویسندگان
چکیده
A model of a magnetic film sense system is presented. Using the model the mean time between false readouts due to random noise is determined as a function of the system parameters; total magnetic flux switched, switching time, sense line resistance, amplifier noise factor and linear amplifier filter efficiency. (The filter efficiency with respect to a given input pulse shape is the signal-to-noise ratio at the output of the amplifier divided by the corresponding signal-tonoise ratio at the output of a filter matched to the pulse shape.) The degradation of signal-to-noise ratio caused by introduction of a quick recovery "short" time constant is determined and shown experimentally . Accepted for the Air Force Franklin C.

Static Coil Design Considerations for the Magnetic Resonance Imaging
One of the main challenges in developing magnetic resonance imaging (MRI) systems is to create a static coil that needs to generate magnetic field density along with the characteristics of optimal homogeneity and magnitude size. To do this, two N42 Block PMs are used and the iron core is designed and optimized in accordance with the dimensions of PM pieces using ANSYS Maxwell software. Then, al...
