In the design of magnets to generate steady high fields, one of the major problems is that of the removal of heat from the windings. This is already severe in conventional magnets at the 100 kOe or 2 MW level, and at higher fields considerable difficulties arise in making a winding which is adequately cooled and yet mechanically strong. The related problem in superconducting coils is that of preventing the conductor from going normal accidentally, and protecting the coil and other apparatus if it should do so. This, however, is more properly dealt with when discussing superconducting coils in Chapter 7. The present chapter is therefore devoted to a discussion of intensive cooling in conventional solenoids, and of the properties of some of the coolants which might be used.
