Abstract

The arc temperature is one of the most important characteristics which cotrol the emission properties of plasma light sources. X-ray absorption technique has received some attention as a powerful method to determine the temperature in high-pressure metal-halide lamps. An important advantage of x-ray diagnostic is its non-invasisve character. Good results can be obtained by using an approach that combines modern x-ray measurement techniques and advanced tomographic algorithms. Computer tomography enables to the absorbing (mercury) atoms density. The temperature profile in this case is derived from the ideal gas law at constant pressure.
