- 3D diamond detector with hexagonal and cubic cells fabricated
- Performance of hexagonal and cubic cells comparable
- Differences in charge sharing observed, important for application scenario
A detector from single crystal synthetic diamond with conducting wires has been prepared with an improved femto-second laser process. The detector was characterised with a 4.5Â MeV proton micro-beam (RuÄer BosÌkoviÄ Institute, Zagreb). The charge collection efficiency and the transient current response have been investigated with high spatial resolution. A hexagonal and square cell geometry is investigated. Both cell geometries show full charge collection at 40Â V bias voltage, and little charge sharing between neighbouring cells. The experimental data is compared to a simulation and qualitative agreement is observed.
