Title: | On the reconstruction of Cherenkov rings from aerogel radiators | Authors: | Cunha, J. Pinto da Neves, F. Lopes, M. I. |
Keywords: | Silica aerogel; Cherenkov counter; Monte Carlo | Issue Date: | 2000 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 452:3 (2000) 401-421 | Abstract: | An event reconstruction algorithm to analyze Cherenkov rings in a Ring Imaging Cherenkov (RICH) detector is considered and the results of a Monte Carlo simulation are discussed. It is demonstrated that aerogel radiators can be used in RICH detectors despite the Rayleigh scattering of light if filtered by a pattern recognition program. The velocity of the particle radiating Cherenkov light, [beta], is determined by a fit to the photon hit pattern, assuming prior momentum measurement by a tracking system. The charge of the particle, z, is obtained from the collected light. The results show that, for the geometries considered, velocity resolutions [sigma][beta]/[beta][similar, equals]1×10-3 and charge resolutions [sigma]Z/Z[similar, equals]10% can be achieved for 5 GeV/c protons and a 2 cm thick aerogel radiator. | URI: | https://hdl.handle.net/10316/4524 | DOI: | 10.1016/S0168-9002(00)00452-6 | Rights: | openAccess |
