Embodiment Construction

[0034] The technical solution of the present invention will be further described below in conjunction with the examples.

[0035] In order to realize the voltage peak measurement of the MV level pulse power device in the intense pulsed radiation environment, the present invention provides a voltage peak measurement method with a MV level wide dynamic range, which is a voltage peak measurement method based on the ion track method, It has the characteristics of simple measurement principle and insensitivity to space charge field and radiation, so it has the unique advantage of carrying out voltage measurement in strong beam current and complex radiation environment.

[0036] The main principle of the voltage peak measurement method based on the ion track method is that the peak energy of ions accelerated by a high-voltage electric pulse has a corresponding relationship with the peak voltage of the electric pulse. After the accelerated charged ions bombard the detection element, ...

Description

technical field [0001] The invention belongs to the field of interaction between high-power high-current pulsed electron beams and matter, relates to a voltage peak measurement method with a wide dynamic range of MV level, and specifically relates to a pulse power device capable of generating high-power high-current pulsed electron beams. MV level high voltage measurement method. 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 measurement of the pulse powe...
