Abstract:
1. A particle accelerator comprising: a magnet to generate a magnetic field, the magnet comprising first superconducting coils to pass current in a first direction to thereby generate the first magnetic field, the first magnetic field being at least 4 Tesla (T); an active return system comprising second superconducting coils, each of the second superconducting coils surrounding, and being concentric with, a corresponding first superconducting coil, the second superconducting coils for passing current in a second direction that is opposite to the first direction to thereby generate a second magnetic field having a magnetic field of at least 2.5 T, the second magnetic field having a polarity that is opposite to a polarity of the first magnetic field; and a single structure on which at least one first superconducting coil and corresponding second superconducting coil are mounted.
