ZETA Test Facility(1975 - 2000)
In the past MPE maintained at the ZETA-Lab a medium-sized facility for scattering low energy X-rays to investigate components for X-ray telescopes, for X-ray cameras, and for monitoring instruments. The employment spectrum of the facility reached from methodological studies on probes for a range of suitable materials over functionality tests of systems to calibrations of high-sensitive measurement intruments. Source chamber (red), beam guide (yellow), specimen chamber (green), detector chamber (blue). Tiff image (8.2 MB)
The sketch to the left shows an overview of the test facility. A tunable source provides a bunch of X-rays with energies between 0.1 and 20 keV. The following collimator system mounted inside a vaccum tube blinds out a parallel X-ray beam from this bunch which can be scattered on test specimen (e.g. mirrors, gratings, filters) inside the specimen chamber. The scattered X-rays will be detected by a proportional counter in the detector chamber. Focalplane instruments can be calibrated in the experimental chamber. Tiff image (1.8 MB) The ZETA Test Facility, proved already since more than twenty years, was always modernized and adapted to state of the art to meet the requirements of progressive projects. In 1991 the data acquisition system was rebuilt and connected to MPE's computer net. Lastly a multi-target X-ray source was developed, installed, and calibrated in 1995 to be able to measure the efficiency of new developed transmission gratings. The various projects performed at the ZETA test facility over the years are compilated in the following table overview.
