Abstract
The beam tube for the Superconducting Super Collider (SSC) is required to have an inner surface of sufficiently high DC electrical conductivity in order to satisfy beam stability requirements. This high conductivity surface will also help to reduce the parasitic heating of the beam tube due to image currents and may have a positive effect on the beam tube cryogenic budget.1 The SSC specification on beam tube conductivity is related to the inner diameter; for diameters of technical interest the product of DC electrical conductivity and thickness (σt) should be in the range of 1–2 x105 Ω−1 under operating conditions which include a transverse magnetic field in the range of 7 T.
