THE PRODUCTION OF INTENSE MAGNETIC FIELDS BY MEANS OF LIQUID NITROGEN COOLED COPPER COILS.
Abstract
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. 2-1/2 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)
