Abstract: A maximum tube voltage value setting module 240a, a warming-up module 240b, a limit tube voltage control module 240c, a limit tube current control module 240d and a focus grid electrode control module 240e of an operation program 240 which respectively correspond to different maximum tube voltage values are stored in storage sections 32a-e of an X-ray tube control apparatus 3. When the maximum tube voltage value of an X-ray tube 1 is changed, an extraction section 34 extracts each module of the operation program 240 which corresponds to the maximum tube voltage value after being changed from the storage sections 32a-e. A communications section 36 sends the operation program 240 comprised of each extracted module to an X-ray tube controller 2 and overwrites it in a memory section 24.

Abstract: An X-ray tube controller measures operation information (filament power supply time in an X-ray tube and a grid voltage value applied to grid electrodes to maintain the tube current value under a predetermined tube voltage). The information is transmitted to an X-ray tube operation information acquiring unit via a communication line. In a storage section of the information acquiring unit, a database written with degree of attrition corresponding to the integrated power supply time of a filament (reduction ratio of thermalelectron emission amount (tube current value at a predetermined G1 voltage) to the initial value (thermalelectron emission amount when the filament is first used) is stored. An attrition degree determination section determines the degree of attrition of the filament from the count of filament power supply time with reference to the database. Also, the attrition degree determination section determines the end of life from the G1 voltage value.

Abstract: An initial image (the image of a slit plate 5 imaged when adjusted to an optimal focal diameter) is stored in a storage section 72 of an X-ray tube adjusting apparatus 7. An acquisition section 74 acquires a test image (the image of the slit plate 5 imaged at the time of adjusting the focal diameter). A presentation section 76 presents the initial image and an image representing the luminance on the initial image (showing a contrast DELTA a between a slit portion 764a and a residual area portion 766a in the initial image) and the test image and an image representing the luminance on the test image (showing a contrast DELTA b between a slit portion 764b and a residual area portion 766b in the initial image) simultaneously (in a comparable manner).

Abstract: PURPOSE: To radiate the X-ray in a wide scope, and to neutralize the static electricity efficiently, by providing a sealing body sealing a gas with a high transmissivity of the X-ray compared to the ambiant gas, to an X-ray injecting part. CONSTITUTION: A soft X-ray injected from an X-ray generator 10 in the condition of a point beam source advances while spreading, passes through a polyethylene thin film, and is injected in a film pack 21. Since a helium gas with a high X-ray transmissivity is filled in the pack 21, the absorption rate of the soft X-ray is low, and the separating rate of the gas is also low in the pack 21. As a result, the soft X-ray permeates the pack 21 with little atenuation, and advances in the air ambiance where a charged article 30 is provided. Since the air has a high X-ray absorption rate, and the ionizing amount of the gas molecules is large, a plenty of ions are produced near the article 30, and the static electricity can be neutralized efficiently.
