| Zusammenfassung | With the robot-based gonioreflectometer of PTB the BRDF (Bidirectional Reflectance Distribution Function) of a gold/titanium coated molybdenum sample was measured at a wavelength of 254 nm. Hereunto the diffuse reflection was measured in 1821 distinct directional geometries in 3D-space around the specular angle for a total of 10 different incidence angles in the angular range 0° to 85°. The characterised sample was an artefact with identical surface properties as the inner surface coating of the electrode housing for the test masses of the LISA (Laser Interferometer Space Antenna) Pathfinder satellite mission. The angular dependent reflection values at 254 nm are essential for radiation transport calculations, since special UV-lamps are applied for the in-orbit discharge of the test masses. |
