Abstract :
As is well known, the space-charge reduced shot noise of a triode can be used as a measure of the cathode emissivity. A simple test equipment is described and results of measurements are discussed. The noise tests seem to be more sensitive than other methods without having any detrimental influence on the valve under test. Application for life test is suggested
