Position-sensitive MCP-based detectors with high timing resolution: some results and perspectives

The microelectronic design and some results of experimental tests of three types of coordinate-sensitive Micro-Channel-Plane (MCP) based detectors with good timing properties are presented. The electrodynamic structures that could be used for the MCP fast signal readout (strips, delay lines and discrete pads) are always a compromise between the amplitude of the induced signal, propagation time delay, cross-talk and distortions of the signal at the output. In-lab tests of these structures and experimental tests of the detectors done with the beams of MIPs and with the alpha-source, have shown a 130 μm spatial resolution and a 110 ps timing resolution obtained simultaneously for one detector.
