  1. Cathode R&D 04/12/06 Saxet project in progress: Tests of samples with thick lines are completed Currently we are trying to reproduce results of samples with fine grids

  2. Summary of previous results Polarization Thin GaAs films with 4mm 2D grid and 48mm pitch 5x1014cm-3 5x1016cm-3

  3. Summary of previous results QE Thin GaAs films with 4mm 2D grid and 48mm pitch 5x1014cm-3 5x1016cm-3

  4. Samples with 50mm metallic lines

  5. QE #39 Thin GaAs 5x1014cm-3 W+Au lines #38 Bulk GaAs W+Au lines #43 Thin GaAs 5x1016cm-3 W lines #41 Thin GaAs 5x1014cm-3 W lines #40 Bulk GaAs W lines

  6. Polarization #39 Thin GaAs 5x1014cm-3 Au+W lines #38 Bulk GaAs Au+W lines #43 Thin GaAs 5x1016cm-3 W lines #40 Bulk GaAs W lines #41 Thin GaAs 5x1014cm-3 W lines

  7. Conclusions and current work • Although hard to conclude the samples with lines have not given an indication of positive results • Currently we are measuring gridded samples 18A and 19B that have given good results in the past
