Abstract
Velocity vector components of a relativistic high energy beam of atomic particles are measured by examination of the Doppler shifts of spontaneous photo emissions from the beam. Beam direction can be calculated directly from measurements made at the Doppler-free angle if beam velocity is known. Beam velocity can be calculated from measurements made at the Doppler free angle or at other convenient angles. A beam steering technique by nulling outputs from diametrically opposed sensors is also disclosed.
