摘要：

The energy and spatial resolution of a large-volume liquid-scintillator detector has been investigated. The relations have been derived, which allow the energy and spatial resolution of the detector to be estimated without modeling. The calculations involve the light-collection functions of the detector obtained either by the Monte Carlo method or in the measurements taken with radiation sources. The relations are verified with the experimental data of the CTF (Counting Test Facility) detector, which is a prototype of the new Borexino detector for solar neutrinos. An event reconstruction technique using charge and time data from the photomultiplier tubes (PMTs) is analyzed with the help of these relations in order to improve the detector resolution. Algorithms for the energy and coordinate reconstruction of individual events are presented.
