Recently it has been experimentally shown that saw tooth shaped p{sup +} strips allows confinement of drifting electrons in the lateral direction. This is achieved by means of potential gutters induced by an appropriate saw tooth design p{sup +} cathodes. The saw tooth period p{sub x} = 500 {micro}m. The final detector is intended to have an anode pitch of 250 {micro}m. The simulation of a saw tooth configuration with p{sub x} = 250 {micro}m, p{sub y} = 200 {micro}m, and {alpha} = 60{degree} showed that potential gutters with a depth of 80 mV will be produced assuming a drift field of 250 V/cm. The authors will give experimental evidence of these shallow charge confining potential gutters.
