Testing an indirectly heated cathode ion source: Temperature and thermionic emission
Here we compare the cathode surface temperatures and thermionic emissions of a novel thermal barrier cathode against original equipment manufacturing (OEM). The new indirectly heated cathode ion source assembly employs a cathode cup unit and filament arrangement, where the filament has a flat face t...
