摘要： Provided is an X-ray generator comprising an X-ray tube including a cylindrical body; an electron source in the body; a target at an end of the X-ray tube facing the electron source, the target generating X-rays by irradiation with electrons; a container in which the X-ray tube is arranged; insulating liquid filled between the X-ray tube and the container; and a holding member holding the body of the X-ray tube in the container, with a channel for the insulating liquid around the X-ray tube. The distance between the holding member and the end face at the end of the body in the direction in which the electron source and the target face is twice or more as large as the minimum width of the channel that is in contact with the outer surface of the X-ray tube at the end face side with respect to the holding member. This allows heat in the target to be quickly radiated, thus allowing X-rays to be generated stably for a long time.

摘要： In an X-ray tube having an X-ray shielding member allowing an electron ray to pass through an electron passing hole toward a target, separately from the cathode-side opening of the electron passing hole, a gas exhaust path allowing communication between the inside and outside of the electron passing hole is provided so that gas molecules generated in the electron passing hole can be easily diffused out of the electron passing hole. The degradation of the cathode caused by accelerated collisions with the cathode, of cations generated by collisions of electrons with gas molecules generated in the electron passing hole by a desorption phenomenon due to electron ray irradiation to the target, is reduced.

摘要： A method for adjusting electron emitting characteristics of a multi-electron source having plural electron emitting devices disposed on a substrate. The method comprises measuring electron emission characteristics of the devices and setting a characteristic adjustment target value. Plural characteristic shift voltages having discrete values are applied to some of the devices, electron emission characteristics of each of these devices are measured, and a characteristic adjustment table is generated for each characteristics shift voltage value according to change rates of these measured characteristics. A predetermined characteristics shift voltage value is selected based on the corresponding table, and that voltage is applied to the devices to cause their characteristics to shift towards the target value. A change in the electron emission characteristics is monitored to revise the characteristics shift condition.

摘要： In a radiation imaging apparatus, an envelope has a first window for transmitting radiation and is filled with an insulating liquid, and a radiation tube in the envelope has, at a position facing the first window, a second window for transmitting the radiation, and a shielding member. A solid insulating member is arranged between the shielding member and the inner wall of the envelope, and an opening is formed at a position on the insulating member corresponding to the first window. The shortest distance from the shielding member to the first window or the inner wall of the envelope through the opening of the insulating member without the insulating member is made to be longer than the shortest distance from the shielding member to the first window or the inner wall of the envelope through the insulating member, thereby improving withstand voltage performance without reducing an radiation amount.
