A novel compact threshold Cerenkov detector

A Compact Gas Čerenkov Detector with Novel Optics

We discuss the design and performance of a threshold Cerenkov counter for identiication of charged hadrons. The radiator is pressurized gas, which is contained in thin-walled cylindrical modules. A mirror system of novel design transports Cerenkov photons to photomultiplier tubes. This system is compact, contains relatively little material, and has a large fraction of active volume. A prototype...

On optimal threshold and structure in threshold system based detector

Threshold systems are widely used in nonlinear signal detection. The optimal threshold and the optimal structure are crucial to obtain good performance. In this paper, we propose an efficient method to estimate optimal threshold in a threshold system based detector (TD). In addition, we investigate the structural issue of TD and propose a technique to determine the optimal structure. An optimal...

Circulation model for water circulation and purification in a water Cerenkov detector

Owing to its low cost and good transparency, highly purified water is widely used as a medium in large water Cerenkov detector experiments. The water circulation and purification system is usually needed to keep the water in good quality. In this work, a practical circulation model is built to describe the variation of the water resistivity in the circulation process and compared with the data ...
