ブラウン管

cathode-ray tube, CRT

[目次：検出系]

電子ビームを電圧や磁界で加速、集束、偏向して蛍光体を照射して管面に二次元画像を表示するもの。

The cathode-ray tube (CRT) displays a two-dimensional image on the tube surface in such a way that an electron beam is accelerated, focused and deflected by electric voltages and magnetic fields to scan the tube phosphor surface.
