The prototype system was tested for endurance capabilities with Ce. System runs made intermittently amounted to 44 hrs. Oxide reaction effects were apparent on inspection of the vaporizer the discharge pores were sealed by a layer of reacted Ce salts. A substitute vaporizer was installed. Approximately 1.75 lb of Ce were transferred from the prototype storage tank 3 weeks after completion f the endurance testing visual inspection indicated no reaction. A method of analyzing system response and operation characteristics with a low flow metering device for liquid Ce is discussed. A calibrated orifice system was proposed flow rates will cover the range from 10 to the -5th power to 10 to the -7th power lb per sec.
