PSI 3 Deep Space 1

PSI 3 Deep Space 1

PSI 3 is a vertically orientated facility. It providesthe possibility of simultaneous radiation exposure of a moderate amount of samples and their corresponding dark references on four stacked and linked copper cooling plates. They guarantee a consistent temperature for both sample layers. Radiation is conducted with polychromatic light emitted from metal halogenide solar simulators (1000 W / 2000 W). A variety of neutral density filters and cut-off filters are available. This simulation chamber has been successfully used for BIOSTACK (EURECA), EXPOSE-E and EXPOSE-R exposure as preparation for the corresponding flight experiment (MGR). The evenly illuminated sample accommodation area on the upper cupper plate assures the simultaneous radiation of a moderate amount of samples with minimal scattering effects. The pumping unit at the facility Deep Space 1 is similar to Deep Space 2 and 3.
