Abstract
We explored wide-pitch ohmic-side structures for the BELLE SVD, where we proposed a field-plate structure combined with narrow p-barriers in between the readout electrodes of 90, 113, 180, and 226 mu m-pitch de tectors. The effect of the p-barriers was studied with a numerical mod el to trace the carrier trajectories. The charge collection and sharin g properties were examined in practice for prototype small-size detect ors with an IR pulse shining from either the junction side or the ohmi c side. The channel separation capabilities were also shown to be appr opriate under nominal operation conditions.
