Abstract

The Heimann company has developed a 1" mixed field saticon (magnetic focus-electrostatic deflection) with diode gun. This new pick-up tube was specifically developed for High Definition Television (HDTV). The key requirements for an HDTV system piick-up tube are: o Very high resolution o Very high signal to noise ratio o Very low lag o Very low stray capacitance The improvements have been achieved through the use of an Se-As-Tle amorphous photocon-ductive target which does not limit resolution due to vitreous stru ture and high resistivity. Also, a diode gun is used which provides a nearly parallel, 1 w temperature electron beam which with electrostatic deflection guarantees optimal linearity. Signal to noise ratio is significantly improved as stray capacity is reduced, and the saticon photoconductive target with diode gun allows signal currents of 3 micro amps or more, his tube has been successfully demonstrated, both in HDTV and Medical X-Ray Imaging Systems as well.
