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

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
