Abstract
A magnetron has a cathode, an anode with vanes, and an insulating surface which faces the cathode and receives material from the cathode due to sputtering at the cathode. A conductor enables the resistance of the film so deposited to be measured, giving an indication of the thickness of the film and the lifetime of the magnetron.
