Acknowledgements

The authors would like to thank F.McDevitt, A.Meikle, F.Doherty and R.Boulter for technical support and all those at the ISIS, CERN PS and PSI facilities during the irradiation runs. One of us (R. Bates) gratefully acknowledges the support received through a CASE postgraduate student ship from RAL. The work carried out with pixel detectors could not have occurred without the collaboration of RD19 with RD8. The results obtained within the RD8 and RD19 collaborations are from work partly funded by PPARC (UK), INFN (Italy), and the BMFD (Germany).
