Abstract

By remodeling the anode-earth type condenser discharge X-ray apparatus into a cathode-earth one, the focus for a 1OkW X-ray tube was reduced by the self bias system. As the focus was magnified by 5 times, changing state of redaction was made elear ; microfocus obtained by this method was 0.2×0.3mm^2 in its size. Exposed time in the radiography was 0.3〜0.5sec. for total discharge was not carried out owing to obstruction of the electron beams due to the grid effect of the bias charge given.
