New Developments in Fast-Sampling Readout of Micro-Channel Plate Based Large Area Pico-second Time-of-Flight Detectors
2009
Abstract
Detectors based on Micro-Channel Plate structures coupled to transmission lines could be used to cover large areas while keeping their outstanding timing properties. This development is a key step towards very large area photo-detectors with excellent space and time resolutions, possible 'game changers' in high energy physics, medical imaging, and security.
A readout device consisting of transmission tines with 3.5 GHz analog bandwidth coupled to the anodes of a 2' x 2' device is presented. Simulations predict that waveform sampling using ASICs in the 10 Giga-sample/second range allows measuring both space with millimeter precision and fast timing at a few pico-seconds resolution.
