In order to develop a high performance HDTV camera, a new combination of electron optics and a HARP target is proposed. A unique lens structure and electrode configuration was adopted in the new 1-inch a11 electrostatic focusing and deflecting system. In the prototype tube, a maximum sensitivity of 32 times that of the standard Saticon was obtained. An amplitude response at 800 TV lines (ITE AR chart) at picture center is about 45%.
