FIG. 1.

(Color) Metal halide lamps. Left: A schematic view with a plasma arc developing between two electrodes. The arrows indicate the convection and diffusion processes of atoms and molecules. Right: a picture of a lamp with a quartz burner. The hot lamp burner is surrounded by a glass jacket, not shown in the left sketch, for safety reasons and to provide a controlled (vacuum or ) environment to the burner itself.

FIG. 2.

(Color) Pictures of a vertically burning lamp in (left), (middle), and (right). The lamp, shown when off in Fig. 1, has a cylindrically shaped quartz wall with an inner diameter of and electrode distance of (aspect ratio 2.25). It is filled with Hg and . The color separation and reduced light emission from the top part is clearly visible during the 1 and phases.

Image of FIG. 3.
FIG. 3.

Light emission of a vertically burning lamp as a function of time during several parabolas. The lamp has a cylindrically shaped polycrystalline alumina (PCA) wall with an inner diameter of and electrode distance of (aspect ratio 4). It is filled with Hg and a NaCe salt mixture.

Image of FIG. 4.
FIG. 4.

Light emission of a horizontally burning lamp as a function of time during several parabolas. The lamp has a cylindrically shaped PCA wall with an inner diameter and electrode distance of (aspect ratio 1). It is filled with Hg and a NaTlDy salt mixture. During the normal and hypergravity phases light emission is equal; only during microgravity the light emission is reduced.
