The investigation was undertaken to study the problem of production of intense, continuous magnetic fields using low temperature coils. Using a standardized 5 in 0.D. 2-12 in wide solenoid configuration, a variety of coolant passage geometries and coil manufacturing techniques for producing coolant passages were tested. The solenoids are evaluated on the basis of cooling ability power dissipated for a maximum flux density and ease of manufacture. With liquid nitrogen being supplied at a rate of approximately 50 GPM, a maximum flux density of 77 kilogauss was measured in a .5 in air bore while dissipating 86 kilowatts of power. Author
