Microampere flux pumps for superconducting NMR magnets Part 1: basic concept and microtesla flux measurement Original Research Article

This paper describes the basic concept of and two microtesla flux measurement techniques for microampere flux pumps to be used in superconducting NMR magnets. Under construction presently at FBML are a prototype flux pump and an LTS/HTS NMR magnet, which will be coupled to a full-scale flux pump to be built after completion of the prototype. The two measurement techniques, independent and complementary, permit quantification of flux increments pumped into a magnet coupled to a microampere flux pump.
