Embodiment Construction

[0018] Such as figure 1 As shown, the detection method used in the process section of the ultra-high vacuum accelerator tube is to carry out voltage training and detection for all the gaps in the process section 4 under test one by one: gradually increase the voltage of the small high-voltage power supply 7 until sparking or leakage occurs in the gap under test Finally, start high-voltage exercise until the voltage rises to 2.5 times the rated working voltage, and reaches the specified leakage and ignition frequency limits, then the gap high-voltage exercise is completed and the quality is up to standard. Only when all the gaps are up to standard, the tested process Section 4 is judged as qualified.

[0019] The detection equipment used for the detection method of the ultra-high vacuum acceleration tube process section is characterized in that it includes a vacuum system 1, a small sealed pressure steel cylinder 3, a high-voltage connection switching operation box 8, a console...

Abstract

The invention discloses a detecting method and detecting equipment for an ultrahigh vacuum accelerating pipe process section and relates to the treatment and detection of an ultrahigh vacuum metal ceramic welded accelerating pipe process section of an electronic accelerator. The voltage training and detection are gradually carried out on all clearances of a detected process section; after the voltage of a small high-voltage power supply is gradually increased till the detected clearances generate fire striking or electricity leakage, the high-voltage training starts to be carried out; when the voltage is raised to 2.5 times of rated working voltage and reaches a specified electricity leakage and fire striking frequency limit value, the high-voltage training of the clearance is finished, and the quality reaches the standard; only if all clearances reach the standard, the detected process section is judged to be qualified. In order to overcome the defects, the invention provides the detecting method and the detecting equipment for the ultrahigh vacuum accelerating pipe process section, which have a scale production way and are beneficial to improving the production efficiency, reducing the cost and ensuring the quality.

Description

1. Technical field [0001] The invention relates to the processing and detection of the ultra-high vacuum cermet welding acceleration tube process section used for electron accelerators. 2. Background technology [0002] The high-voltage accelerating tube is the core component of a high-voltage accelerator, which accelerates charged particles (electrons or ions) under the action of a high-voltage electrostatic field and converges them into beams. The traditional high-voltage accelerating tube is composed of a number of glass rings and metal electrodes alternately stacked one by one, combined by bonding or sintering, and has high dimensional accuracy, structural strength and air tightness. [0003] The ultra-high vacuum cermet welding accelerating tube is a more advanced accelerating tube, which uses alumina ceramic rings and titanium electrode sheets, and is welded by brazing or pressure diffusion in a vacuum furnace, completely eliminating the intervention of organic matter ...
