Electrostatic deflection

Japanese: 静電偏向 - せいでんへんこう(英語表記)electrostatic deflection
Electrostatic deflection
Also called electric field deflection. A method that uses an electric field to change the direction of an electron beam. In an electric field, electrons experience a force in the opposite direction to the electric field, so this can be used to change the direction of the electron beam. A high voltage is required to deflect the beam at a large angle, but since the deflection accuracy is good, this method is used in small cathode ray tubes for measurement such as synchroscopes. (→ Magnetic field deflection)

Japanese:
電界偏向ともいう。電子ビームの方向を変えるために電界を用いる方式。電界中で電子は電界と反対方向に力を受けるので,これを利用して電子ビームの進行方向を変えることができる。大きな角度に偏向するには高い電圧が必要であるが,偏向精度がよいので,シンクロスコープなどの計測用小型ブラウン管に用いられている。 (→磁界偏向 )
