Abstract

At research of high speed gas-dynamic processes x-ray image recording method is widely applied. The informativity of this method is defined by characteristics of the x-ray image formation system, which consists from x-ray or gamma- radiation source and a system of images recording. Application of developed in RFNC VNIIEF electron-optical recorders of the x-ray images has allowed to realize multi- frame recording of gas-dynamic processes and to expand methodical opportunities of x-ray imaging technique. The ways of technical realization of the high speed electron- optical recorders for single and multi-frame recorders for single and multi-frame recording are stated. Experimental results of check and the main characteristics of the electron-optical recorders are discussed. It is shown, that the sensitivity of such recorders can be changed in very wide range up to limiting, when each absorbed gamma-quantum is registered. At present in RFNC VNIIEF the electron- optical recorder `FIAR' is developed and widely applied. The result of four frames recording of plasma jet development on an output of plasma covering device also presented as an example of the recorder work. Prospects of development and perfection of characteristics of the electron-optical recorders and expansion of their application field are considered. An opportunity of creation of the x-ray image recorder with sensitive field above 4 square meters, enabling to receive the information on researched object in real time mode is shown. The design of such recorder permits fast adaptation for the requirements of gas-dynamic experiment.
