The MBB Space Division operates its solar radiation simulation test facility since 1973. This test equipment is fully automated and runs without interruption 24 hours a day, as long as specified, with its radiation sources operating simultaneously or alone. The test chamber provides clean vacuum. The sample temperatures are adjustable between -30 Cel and +100 Cel. UV - radiation exposures may be accelerated up to 6 solar constants. The electron and the proton current densities can be selected from 10(exp-10) amps/cm2 to 10(exp-8) amps/cm2. Their energies may range from 5 KeVolts to 60 KeVolts. Eight samples size 11 x 11 mm are exposed simultaneously, or four samples 20 x 20 mm. For assessment of damages inflicted a spectrometer is mated to the vacuum chamber for In Situ measurement of sample spectral reflectances from 240 nm to 2,5 um. 132 of these data in real time are transferred into the sample solar absorption coefficient. With this test equipment a broad variety of thermooptical materials has been studied. The test results have been published in technical journals, technical reports, and in conference proceedings (Ref. 1).
