Dual Readout: 3d Direct/induced-signals Pixel Systems

摘要

In this paper, 3D-eIectrode pixel detectors are described, in which the bias electrode systems have additional elements. Adding resistors between the bias supply line and each bias electrode together with a signal electrode readout that can measure pulse heights of both polarities could simultaneously provide lower capacitance and improved spatial resolution in both directions. A separate paper ("Dual-readout-strip/pixel systems") covers an alternative-pixels with an added strip readout in one direction which could be used with either planar or 3D-electrodes, and could simultaneously provide a fast trigger and significantly increase the spatial resolution in both directions.
