Abstract

The invention relates to the technical field of ultra-fast diagnosis. With regard to the problems of low sensitivity, low space resolution, high-voltage driving required and the like of a traditionalframing image conversion tube, the invention proposes a framing image conversion tube and a framing camera. The framing image conversion tube comprises a framing tube shell and is characterized also by comprising a transmission-type negative electrode microstrip substrate, an electron multiplier and a fluorescent screen which are sequentially arranged on the framing tube shell, the transmission-type negative electrode microstrip substrate can transmit ultraviolet light or soft X ray and is fixedly arranged on the framing tube shell, at least one transmission-type negative electrode microstripis plated on a lower surface of the transmission-type negative electrode microstrip substrate, high-voltage gating pulse generated by a high-voltage pulse generation and transmission system is transmitted on the transmission-type negative electrode microstrip, the electron multiplier is used for multiplying electrons generated by photoelectric conversion when the transmission-type negative electrode microstrip is used as a negative electrode, and the fluorescent screen is used for converting the electros to photons under bombardment of the multiplied electrons, imaging and outputting.

Description

technical field [0001] The invention relates to the technical field of ultrafast diagnosis, in particular to a frame-changing tube and a frame-changing camera. Background technique [0002] A microchannel plate (MCP) traveling-wave gated framing camera is a two-dimensional image acquisition device for ultrafast phenomenon diagnosis in the X-ray and ultraviolet spectral ranges, with applications ranging from nuclear physics to biomedical photonics , plasma physics, strong field physics and other new disciplines are necessary diagnostic equipment for inertial confinement fusion experiments. [0003] The microchannel plate (MCP) traveling wave strobe framing camera is mainly composed of a high-voltage pulse generation transmission system and a framing transformation tube. The high-voltage pulse generation transmission system generates a high-voltage strobe pulse to drive the cathode microstrip; the framing transformation The tube is composed of reflective cathode microstrip, m...
