Characterization of plasma filling in hohlraum using X-ray framing camera

WT5”BZ]An analytical method has been used to study the non uniformity of plane radiation field produced by lasers heating hohlraum.

X-ray confinement and energy redistribution in a hohlraum is one of the foremost problems in the indirect-drive approach to inertial confinement fusion (ICF).

Continuous temperature measuring device for liquid steel in CC tundish by black body cavity;

The present paper describes the theoretical base, structural principle, calibration method, results of tests and analysis as well as on site application conditions of the black body cavity based continuous temperature measuring system for hot metal temperature measurement.

Presents two factors of black body cavity′s accuracy according to Kirchhoff′s law,and gives a theoretical equation of these factors.

This paper presents the application of a blackbody cavity-based continual temperature measurement system at the Steelworks to realize a continual temperature measurement of liquid steel in the tundish,and expounds its working principle.

The important performance of it is the uniformity of the temperature distribution of the blackbody cavity and the maximum difference of temperatures from the base to 150 mm along the wall is only 2～4 ℃,The accuracy of the built blackbody cavity has been e.

Integrated emissivity of compound temperature sensor is not equal to unit, because of the non-isothermalness and non-airtightness of actual blackbody cavity.

Research on characteristic parameter of sapphire fiber blackbody cavity transient high temperature sensor measurement system;

The extrapolation model which describes the transient heat transfer in blackbody cavity is established after analyzing the heat transfer law of blackbody cavity.
