Embodiment Construction

[0046] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0047]The operating voltage of the flash X-ray machine is from hundreds of kV to several MV, the irradiation amount is from several mR to hundreds of R, and the pulse width is below hundreds of ns. Its main components include X-ray diode 3, high-voltage ns pulse generator (pulse source), control system, etc., wherein the first two constitute the flash X-ray source (light source), and the high-voltage ns pulse drives the X-ray tube to output the flash X-ray during operation. The high-voltage ns pulse power source system has always been composed of Marx generators, pulse transmission lines, accelerators, etc. The common feature of these pulse sources is that they convert AC or DC power into instantaneous high-energy pulse output through comple...

Abstract

The invention discloses a ferroelectric explosive-electric energy exchange pulse generator, a flash X ray generating device and a flash X ray generating method, wherein the ferroelectric explosive-electric energy exchange pulse generator comprises PZT ferroelectric ceramics, a positive electrode, a negative electrode and a plane impact device, wherein the positive electrode and the negative electrode are arranged at two ends of the PZT ferroelectric ceramics; the plane impact device is arranged below the negative electrode. The explosive-electric energy exchange pulse generator is arranged fortaking an explosive-electric energy exchange pulse source as a primary energy source of a spiral pulse generator, so that the pulse source in a flash X-ray machine does not rely on external alternating current / direct current power supply conversion.

Description

technical field [0001] The invention relates to a ferroelectric explosive energy transducing pulse generator, a flash X-ray generating device and a method. Background technique [0002] Flash X-ray imaging diagnosis is a modern testing technology. It uses a high-voltage pulse generator to drive a flash X-ray diode to generate very short X-ray pulses. Transient processes and high-speed motion phenomena. Therefore, it has been widely used in the testing of detonation physics, implosion dynamics, shock wave physics, high-energy explosives, internal ballistics, armor and anti-armor research, and transient process research in the fields of plasma physics, materials, biology, and medicine. Many countries, including my country, have developed various flash X-ray equipment. But driving the pulse source needed to generate the flash X-ray diode requires a separate external AC / DC power conversion. [0003] The ferroelectric explosive transduction pulse generator is considered to be o...
