Embodiment Construction

[0027] The technical solutions and technical effects of the present invention will be further described below in conjunction with examples.

[0028] In order to realize the voltage peak measurement of the MV level pulse power device in the intense pulsed radiation environment, the present invention proposes a MV level voltage peak measurement probe, which is a filter-type solid nuclear track detection based on the ion track method The device mainly includes a detection element 2, a fastening sleeve 4, an aluminum membrane filter 3 and a stage 1. Among them, the detection element 2 uses a solid nuclear track detection element with a wide detection threshold energy, which can increase the range of detectable voltage peaks, and can measure the energy of hydrogen ions above several MeV. An aluminum membrane filter 3 is added in front of the solid nuclear track detection element, so that It works in the environment of high fluence, high pollution and complicated ion source. The sta...

Abstract

The invention belongs to the field of research on the interaction between high-power high-current pulsed electron beams and substances, and relates to a MV-level voltage peak measurement probe and a manufacturing method thereof, which can perform MV-level high-voltage measurement, and solve the problem that the existing pulse voltage measurement method is not applicable Several MV voltage measurement problems. The MV-level voltage peak measurement probe includes a detection element, an aluminum film filter, a stage and a fastening sleeve; the detection element is a solid nuclear track detection element with a wide detection threshold; There is an installation groove on the top of the boss, and the detection element is set in the installation groove; the aluminum film filter is a plate-shaped structure, which is arranged above the installation boss to cover the detection element; the fastening sleeve is set on the installation boss on the platform, and press the aluminum membrane filter on the installation boss. The MV-level voltage peak measurement probe of the invention has a very wide voltage peak measurement range, and can realize voltage peak measurement of several MV or more.

Description

technical field [0001] The invention belongs to the field of research on the interaction between high-power high-power pulsed electron beams and matter, and relates to a MV-level voltage peak measurement probe and a manufacturing method thereof, in particular to a pulse power device capable of generating high-power high-current pulsed electron beams. Probe for making high voltage measurements in the MV class. Background technique [0002] The pulsed power device can generate high-power intense pulsed electron beams, and the interaction between the high-power intense pulsed electron beams and high atomic number substances is an important technical means for laboratories to generate intense pulsed radiation environments. In particular, for a pulsed power device that generates a strong pulsed gamma ray environment, in order to increase the intensity of the radiation field output by the device, the peak value of the voltage pulse is usually several MV to tens of MV. The voltage...
