Beam current sensor
A sensor is described for measuring the current of a beam of charged particles, comprising: a. superconducting probe means comprised of a hollow probe having interior and exterior surfaces and surrounding the beam of charged particles, having a continuous slot surrounding the beam of charged particles whereby the interior and exterior surfaces join each other, the slot thereby forming first and second ends of the superconducting probe means such that a current is induced on the exterior surface of the superconducting probe means, the induced current on the exterior surface acting to exclude magnetic flux associated with the beam from interior regions of the probe means in accord with the Meisner effect; and b. superconducting detection means coupled to the probe means and responsive to the current induced therein for providing an output voltage representing the current of the beam of charged particles.
