摘要：
The COST reference lamp is a High Intensity Discharge (HID) Metal-Halide (MH) lamp that has been designed to introduce a unified lamp system used in experimental investigations and numerical simulations done by various groups working on HID lamps. By using this lamp, designed to be accessible for a variety of diagnostic techniques, measurements of various plasma parameters can be fitted together to obtain a more complete understanding of the physics of these lamps. In this paper we discuss the mechanisms responsible for colour segregation in MH lamps. The discussion is aided by experimental and numerical data obtained from studies of the COST lamp: emission spectroscopy under varying gravity conditions, x-ray induced fluorescence and numerical modelling by means of the two-dimensional fluid model toolkit Plasimo.
