The calculation of optical properties of cesium plasma under conditions of a pulse-periodic discharge

The calculations of the radiation spectrum, the color rendering index R _a , the color temperature T _c , and the color coordinates X _c and Y _c of cesium plasma radiation under the conditions characteristic for a pulse-periodic discharge in cesium are presented. The plasma pressure range of 30–1500 Torr and the range of temperatures on the axis of 3200–6000 K are considered. The color rendering index is shown to be R _a > 90 in the entire analyzed plasma parameter ranges. The color temperature of plasma radiation varies within a broad range of 2300–5500 K. The color coordinates of the cesium plasma radiation are close to the X _c and Y _c coordinates of a black body.
