yoke
(Science: microscopy) The assembly of electromagnetic coils that are placed over the camera tube or the neck of a picture tube or a cathode–ray tube of the magnetic focusing type. The focusing coil in the yoke controls the convergence of the electron beam. The H- and V-deflection coils deflect the electron beam so that it sweeps the target or phosphor in a standard video raster.
