DEVICE TO SUPPLY VAPOUR OF CAESIUM INTO THERMIONIC CONVERTER Russian patent published in 2012 - IPC H01J45/00 

FIELD: electricity.

SUBSTANCE: device is proposed to supply vapour of caesium into a thermionic converter of a thermionic converter, comprising a source of caesium vapour, made of pyrolytic oriented caesium graphite, and placed in a body with a heater installed on it, at the same time the source of caesium vapour is arranged in the form of a hollow cylinder placed between two plates sealing the upper and lower planes of the cylinder, the upper of which is solid, at the same time the cylinder cavity is connected with a reservoir with a source of liquid caesium condensate, the inner volume of which is tightly closed with a source of vapour from a working volume. On the reservoir with liquid caesium condensate there is a heater installed and a nozzle with a valve, and the source of caesium condensate is arranged in the form of a capillary structure with liquid caesium condensate.

EFFECT: higher capacitance by caesium.
