Abstract: AbstractA high quality deflection yoke (DY) is one of the most important factors for a high quality monitor. The role of the deflection yoke is to deflect electron beams in horizontal and vertical directions. If the magnetic field is formed incorrectly, misconvergence of beams may occur resulting in blurred image on the screen of the monitor. The magnetic field of DY may be corrected by sticking one or several ferroelastic shunts on the inside surface of the deflection yoke. Also some secondary balance parameters need to be controlled. Because of the complexity of the process it is not easy to determine how to stick the shunt. Therefore, two optimization methods were used for optimal tuning shunts position finding. This paper present research results and its application in industry.
