Electromagnetic and Thermal Aspects of a Fast Field Cycling NMR Equipment Magnet and Power Supply

The Fast Field Cycling Nuclear Magnetic Resonance (FFC-NMR) technique has been spreading its application to new areas such as oil and food industry. Consequently, new features and improvements concerning the equipment available has been investigated and exploited. Under this context, this paper describes the main aspects concerning the electromagnetic and thermal behavior of the main power supply and the magnet, respectively. The proposed power supply and the magnet were developed under the specifications of the FFC-NMR equipment and in order to match the requirements of the most recent areas of application. The dynamic behavior of the power supply is analyzed based on simulation results, being the thermal study of the magnet performed using finite element method software.
