摘要： PROBLEM TO BE SOLVED: To improve the sensitivity for velocity modulation with a simple structure while suppressing an increase in driving power, and further to correct PQH misconvergence.
SOLUTION: A pair of velocity modulation coils 52a and 52b are arranged to sandwich therebetween a horizontal plane including a tube axis. A pair of magnetic components 54a and 54b are arranged to sandwich therebetween a vertical plane including the tube axis. Linear parts 53a extending nearly parallel to the tube axis of the velocity modulation coils are disposed between the tube axis and the magnetic components. An open part 55 between the pair of magnetic components forms an angle θ of 50 to 90 degrees with respect to the tube axis. The magnetic components have protrusions 56a, 56b protruding toward the tube axis that are located at positions intersecting the horizontal plane including the tube axis.
