Abstract
We have developed the 18-mm-diameter all-electrostatic Super-HARP came ra tube for high-performance handheld HDTV cameras. In designing its e lectron optics, we focused on high resolution and a wide dynamic range . Through experiments and numerical analysis, we have optimized the be am-limiting aperture of the diode-gun to enlarge the dynamic range, an d the shape and arrangement of the pattern electrodes in the focusing and deflection system to improve the resolution. A prototype tube exhi bited a dynamic range of at least 800% and maximum resolution of more than 1400 TV lines. The new HDTV camera tube thus achieves a good bala nce of high resolution and wide dynamic range while being compact.
