Abstract Uniform Field Solenoid Magnet With Openings A solenoidal magnet coil is used to generate an axial field for focusing a beam of electrons through a linear-beam electron tube. In high-power tubes, the coil typically cannot extend over the entire length of the focused electron beam because it would interfere with the waveguide used to carry out the generated wave power. Thus the axial mag- netic field strength falls off near the output end, a region in which it would be desirable to have it uniform or even slightly increasing. Very often the coil is foil-wound and its output end has a notch to allow passage of the waveguide. A similar notch 180 degrees away compensates the sideways distortion of field caused by displacement of coil current away from the notch impediment. In the non-notched regions the current spreads throughout the coil cross-section, but there is still a fall-off of field strength on the axis due to current displacement away from the output end. The invention comprises a second pair of notches in the end of the coil opposite the output end and azimuthally spaced between the first pair. These notches deflect the current toward the output, compensating the magnetic field fall-off.
