Resumo(s)
In this article a Fast Field Cycling (FFC) Nuclear
Magnetic Resonance (NMR) electromagnet with low power
consumption (less than 200 W), high field homogeneity and
reduced volume is projected and described. The electromagnet is
iron and copper based, possessing a high permeability and
allowing for good magnetic field homogeneity in the operating
range of 0 to 0.33 T. With this solution, it is possible to increase
65% the maximum magnetic field keeping the magnetic field
homogeneity in comparison with former similar FFC
relaxometers. Electromagnet's experimental and simulation
results evaluating the generated magnetic field, field
homogeneity, heating effects and cooling requirements are also
presented. In addition, some technical aspects of the required
coupled systems such as the cooling, sample heating are assessed.
