Position-sensitive hybrid particle detector based on discrete-time readout.

In this work a new readout scheme for scintillator-based detectors, using discrete time differences through a delay line is proposed, reducing the readout channels while maintaining the spatial resolution. A prototype was built using plastic scintillator blocks and MPPC sensors. Currently, the prototype produces discrete distributions with a dispersion < 1. 1 ns which allows discriminating the different positions. The estimated spatial resolution is σ = 1. 456 mm. This value presents a better resolution than that of Time-of-Flight detectors and of the order of Segmented detectors, but uses fewer readout channels. It is expected to improve this resolution using interpolation effects and testing with larger scale instruments. [ABSTRACT FROM AUTHOR]
