Abstract

Автоэмиссионный холодный катод (11) для использования в электровакуумных приборах. Углеродный бархатный материал (25) состоит из углеродных волокон с высоким отношением длины к поперечному размеру, заделанных перпендикулярно в материал основы. Кончики и/или тела углеродного бархатного материала (25) покрыты цезиевой солью с низкой работой выхода. Материал основы углеродного бархатного материала (25) присоединен к катодной поверхности (27). Холодный катод (11) испускает электроны при приложении электрического поля даже при рабочих температурах менее 900°C.Международная заявка была опубликована вместе с отчетом о международном поиске.Field emission cold cathode (11) for use in vacuum devices. The velvet carbon material (25) consists of carbon fibers with a high ratio of length to transverse size, embedded perpendicular to the base material. The tips and / or bodies of the carbon velvet material (25) are coated with cesium salt with a low work function. The base material of the carbon velvet material (25) is attached to the cathode surface (27). The cold cathode (11) emits electrons when an electric field is applied, even at operating temperatures of less than 900 ° C. The international application was published along with an international search report.
