Characterization of the composite bolometer with a high-Tc superconductor thermometer for an absolute radiometer of synchrotron radiation

The article describes the structure and calculation modeling of characteristics of the detector for an absolute synchrotron radiation radiometer in the soft X-ray range of 8–0.4 nm. The detector is a bolometer working on the principle of substitution of electrical power for radiation power, with a high-temperature superconductor film as an element, sensitive to heat. The noise-equivalent power is predicted to be down to 4×10−11 W/Hz1/2 at 10 Hz.
