This facility could allow to test both the readout chips and the pilot chips for the pixel readout system. In fact, both ASICs will have to survive at the same radiation level foreseen for the innermost layer (r = 4 cm) of the Inner Tracker System (ITS) in the LHC-ALICE experiment. Two test chips were exposed to an overall flux of 1.3 x 10<SUP>12</SUP> 14 MeV neutrons/cm<SUP>2</SUP>, which is larger than the expected neutron flux in ALICE during 10 years data taking. No variation in the parameters defining the chip functionality (analog and digital currents, linearity, shapes of the signal, efficiency) was observed.</P></BODY> </HTML>
