Title:
QUICK DETECTION SYSTEM FOR PHOTOELECTRIC CATHODE OF X-RAY STREAK CAMERA
Document Type and Number:
WIPO Patent Application WO/2019/137096
Kind Code:
A1
Abstract:
A quick detection system for a photoelectric cathode (201) of an X-ray streak camera, comprising a light source (10), a vacuum chamber (20), a trine streak image converter tube group, a CCD camera (302), and a computer (40). The light source (10) emits a test light signal to the incident end of the trine streak image converter tube group. The trine streak image converter tube group comprises a first streak image converter tube (T1), a second streak image converter tube (T2), and a third streak image converter tube (T3). The CCD camera (302) is provided on the emergent end of the trine streak image converter tube group and used for acquiring a test image of the emergent end of the trine streak image converter tube group. The CCD camera (302) is connected with the computer (40). The computer (40) is used for processing the test image. By adjusting the voltage, structure and relative position of the trine streak image converter tube group, three slits are simultaneously imaged in a detectable center area of the CCD camera (302), and three photoelectric cathodes (201) can be replaced by opening a cathode replacing window (202) of the vacuum chamber (20), so that simultaneous and quick detection of the photoelectric cathodes (201) of the X-ray streak camera can be achieved.
