Abstract

The secondary electron emission of pure metals, cathodes and insulators was measured. The secondary electron emission yield was measured at room temperature and at temperatures up to 1100 degrees C. The cathodes were life-tested at 850 degrees C and were measured at regular intervals at room temperature during a period of 10000 h. The best pure material for cathodes was found to be platinum, while oxide cathodes were the best candidates among complex cathodes. The secondary emission of thin insulating films of alumina and magnesium oxide was also investigated. The results found are in good agreement with those published.<>
