Description

technical field [0001] The invention belongs to the field of soft X-ray radiation flow measurement, in particular to a transmission-type flat-response soft X-ray radiation flow measurement device. Background technique [0002] In laser fusion research, radiation flow exists in the entire physical process, including X-ray radiation flow in black cavity physics, self-luminescence in implosion physics, and so on. In order to study the intensity and radiation temperature of the black cavity radiation source, as well as the symmetry of the implosion radiation and the thermonuclear combustion process, the measurement of the radiation flow is indispensable. [0003] At present, the main equipment for measuring radiation flow includes flat response X-ray diode (FXRD), soft X-ray spectrometer (SXS) composed of X-ray diode (XRD) array and other equipment. Flat response XRD is a detector that uses composite filter and XRD to achieve X-ray flat response. XRD cathode sensitivity decrea...
