Ring identification and pattern recognition in ring imaging Cerenkov (RICH) detectors.

摘要

An algorithm for identifying rings in Ring Imaging Cherenkov (RICH) detectors isdescribed. The algorithm is necessarily Bayesian and makes use of a Metropolis-Hastings Markov chain Monte Carlo sampler to locate the rings. In particular, thesampler employs a novel proposal function whose form is responsible for significantspeed improvements over similar methods. The method is optimised for findingmultiple overlapping rings in detectors which can be modelled well by the LHbCRICH toy model described herein.
