A New Method for Determining Thermionic Work Function of Metals and Its Application to Nickel
A new method for determining thermionic work functions of metals has been developed and may be stated as follows: The metal sample has the approximate form of a sphere and is heated by electron bombardment from an auxiliary filament that is disconnected when measurements are made. As the sample cools the electron emission from it charges a condenser, which, at predetermined times, is discharged through a ballistic galvanometer. A Pt, Pt + 10 per cent Rh thermocouple, spot welded to the sample, measures its temperatures.
