[Increasing the anode characteristics of sharp-focused Coolidge X-ray tubes by changing from a high to a low vacuum].
The anode characteristics of up-to-date sharp-focused Coolidge X-ray tubes are analyzed. The reason for differences in the real anode characteristics from theoretical ones has been found to be a higher tube gas pressure than that accepted. There is evidence that there are new third-class X-tubes--electronic tubes with compensation for negative volumetric charge of electrons with positive gas ions.
