Abstract
A scheme for conductor and coolant arrangement in a stacked-plate superconducting magnet is described, which includes arranging coolant and conduction channels on opposing faces within the plates. When two types of channels are aligned with each other across the plate stack, the plates can be stacked so that the cooling channels in one plate are adjacent to the conduction channels of an adjacent plate. By stacking several of these plates, therefore, cooling can be supplied to each conduction channel through the cooling channels of each adjacent plate. Furthermore, by aligning the two types of channels, the plate stack can have improved mechanical strength because a mechanical load path can be created through the entire stack that does not pass through any of the channels. This arrangement of channels can produce a very strong stack of plates that can withstand high Lorentz loads.
