Method and apparatus for measuring the momentum, energy, power, and power density profile of intense particle beams

A method and apparatus for determining the power, momentum, energy, and power density profile for high momentum mass flow. Small probe projectiles of appropriate size, shape and composition are propelled through an intense particle beam at equal intervals along an axis perpendicular to the beam direction. Probe projectiles are deflected by collisions with beam particles. The net beam-induced deflection of each projectile is measured after it passes through the intense particle beam into an array of suitable detectors
