Abstract: A GAS PUMP OF SIMPLIFIED, STURDY CONSTRUCTION EMPLOYS PALLADIUM MAINTAINED AT AN ELEVATED TEMPERATURE TO PERMIT EFFICIENT EVACUATION OF GAS FROM A REGION OF LOW PRESSURE TO A REGION WHERE PARTIAL PRESSURE OF THE GAS IS SEVERAL ORDERS OF MAGNITUDE HIGHER. THE CYLINDRICAL SHAPE OF THE PUMP PROVIDES INCREASED MECHANICAL STRENGTH AND IMPROVED MAINTENANCE OF DIMENSIONAL CHARACTERISTICS,

RESULTING IN UNIFORM HEATING OF THE PUMP WALLS AND CONSEQUENTIAL HIGH IONIZATION EFFICIENCY. TITANIUM RINGS AT EITHER END OF THE PALLADIUM FURTHER IMPROVE PUMP EFFICIENCY.
