Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Magnetic confinement nuclear fusion nuclear measurement imaging diagnosis requires system test calibration and normal measurement operation before and during the measurement, so the radioactive source and pinhole mechanism must be replaced frequently. Due to the radioactivity of the radioactive source and the vacuum tightness of the diagnostic system, cumbersome procedures and steps are required to replace the radioactive source and the pinhole mechanism, thereby reducing work efficiency and affecting measurement accuracy. In order to simplify operation and improve efficiency and precision, we have designed a vacuum dynamic sealing imaging pinhole and radioactive source compound adjustment mechanism.

[0027] Such as figure 1 and figure 2 As shown, the mechanism includes: lifting handle 1, positioning and fixing pin 2, movin...

Abstract

The invention relates to the technical field of plasma diagnosis, in particular to a vacuum dynamic seal imaging pinhole-radioactive source composite adjusting mechanism. According to the invention, abipolar cone small hole and a radioactive source chamber are connected through a movable connecting rod and placed in a sealing chamber composed of a sealing pressing sleeve, a sealing ring and a sealing flange; and positioning switching is conducted through the adjusting mechanism, so accurate switching between an imaging pinhole and a radioactive source of a nuclear measurement imaging diagnosis system of a nuclear fusion device is achieved. With the adjusting mechanism in the invention, accurate switching between the imaging pinhole and the radioactive source of the vacuum sealing imagingdiagnosis system is effectively solved, replacement difficulty and replacement procedures are greatly simplified, test calibration efficiency and the precision of a measurement result are improved, and the adjusting mechanism is applicable to a magnetic confinement nuclear fusion nuclear measurement imaging diagnosis system.

Description

technical field [0001] The invention relates to the technical field of plasma diagnosis, in particular to a composite adjustment mechanism for vacuum dynamic sealing imaging pinholes and radioactive sources. Background technique [0002] There are two main tasks to be completed before and during the measurement of magnetic confinement nuclear fusion nuclear measurement and imaging diagnosis: [0003] 1. Before the measurement, install the radioactive source to the small hole imaging position to debug and calibrate the diagnostic system, such as: collimation of the optical path, shape of the output pulse, energy calibration, etc.; [0004] 2. During the measurement, the imaging pinhole mechanism is adjusted and installed to the position of the pinhole imaging for plasma imaging measurement. [0005] Therefore, the radioactive source and the pinhole mechanism need to be replaced frequently during debugging, calibration and measurement in nuclear measurement imaging diagnosis....
