| Popis: | We evaluated the X-Y position resolution achievable in 3D pixelated detectors by processing the signal waveforms readout from neighboring pixels. In these measurements we used a focused light beam, down to 10 μ m, generated by a ∼1 mW pulsed laser (650 nm) to carry out raster scans over selected 3 × 3 pixel areas, while recording the charge signals from the 9 pixels and the cathode using two synchronized digital oscilloscopes. |
