The thermal emisson of positive K⁺ ions from a tungsten filament occuring as positive pluses (bursts) [1,2] were investigated. Duration of a pulse was about 10 µm and each pulse corresponded to the emission of a group of 10³ to 10⁶ single charged ions. It was observed that the potassium ions originating from the impurities deposited in cavities and dislocations in the polycrystalline tungsten filament. The paper presents statistical parameters of this emission.
