Radiation generating apparatus and radiation imaging apparatus

摘要

The present invention relates to a radiation generating apparatus which includes an envelope provided with a first window through which radiation is transmitted, a radiation tube housed in the envelope and provided with a second window through which the radiation is transmitted, the second window being located at a position opposite the first window, and an insulating fluid adapted to fill the space between the inner wall of the envelope and the radiation tube. Plural plates are arranged side by side between the first window including its periphery and the second window including its periphery, and overlapping one another with gaps between them. The gaps are formed among the plates, and thereby the withstanding voltage between the first window and second window is made larger.

1. An X-ray radiation generating apparatus comprising:
an envelope having a first window through which X-ray radiation is transmitted; an X-ray radiation tube held within said envelope, having a second window through which the X-ray radiation is transmitted, and being arranged such that said first and second windows are opposite to each other; an insulating fluid filling a space between said envelope and said X-ray radiation tube; and a plurality of insulating plates arranged overlapping each other in the radiating direction such that the X-ray radiation is passed through each of said insulating plates in turn, and separated from each other by gap(s), between said first window and said second window.
