  We describe an experimental setup developed aiming to irradiate samples under
UV radiation for accelerated test for solar effects according to the relevant
ECSS-ESA standards. This facility has been already used for projects belonging
to large space programs (Cosmic Vision, Artes) for simulations up to 3500
equivalent sun hours. In particular, we detail the calculation of the UV dose
delivered by Sun, the calibration of the detectors, the spatial distribution of
the UV radiation on samples, the remote control of both samples temperature and
lamp radiation, the samples heat dissipation and operation in a helium
atmosphere.
