Title:
X-RAY GENERATION DEVICE AND ANALYSIS APPARATUS PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2018/002977
Kind Code:
A1
Abstract:
An X-ray generation device (1) is provided with: an X-ray tube (10) having a housing (13), a target (11) that is an anode disposed inside the housing (13), and a filament (12) that is a cathode disposed inside the housing (13), the X-ray tube (10) accepting thermal electrons radiated from the filament (12) at the target (11) and emitting an X-ray generated at the target (11); a high-voltage power supply (20) for applying high voltage to the target (11); a low-voltage power supply (30) for applying low voltage to the filament (12); a high-voltage power supply control circuit (40) that controls the high-voltage power supply (20); and a low-voltage power supply control circuit (50) that controls the low-voltage power supply (30). In order to stop the X-ray generation device (1), after the high-voltage power supply control circuit (40) has stopped applying high voltage to the target (11), the low-voltage power supply control circuit (50) applies a predetermined value of low voltage to the filament (12) for a predetermined time period.
