using electron multiplying ion barrier membrane for vacuum tube, electron multiplying structure for vacuum tube using electron multiplying, and a vacuum tube using electron multiplying with such an electron multiplying structure

摘要

PROBLEM TO BE SOLVED: To provide an improved electron multiplying structure for use in vacuum tube using electron multiplying, which has an improved performance in term of shielding capabilities against stray ions and reduced loss of emitted electrons.;SOLUTION: The invention comprises an input face (7) intended to be oriented in a facing relationship with an entrance window (2) of the vacuum tube, and an output face (8) intended to be oriented in a facing relationship with a detection surface (3) of the vacuum tube, as well as an ion barrier membrane (10) for shielding off stray ions. The ion barrier membrane (10) is composed of at least one atomic layer containing grapheme.;COPYRIGHT: (C)2010,JPO&INPIT
