英文摘要	The hybrid Tibet AS array was successfully constructed in 2014. It has 4500 m(2) underground water Cherenkov pools used as the muon detector (MD) and 789 scintillator detectors covering 36900 m(2) as the surface array. At 100 TeV, cosmic-ray background events can be rejected by approximately 99.99%, according to the full Monte Carlo (MC) simulation for gamma-ray observations. In order to use the muon detector efficiently, we propose to extend the surface array area to 72900 m2 by adding 120 scintillator detectors around the current array to increase the effective detection area. A new prototype scintillator detector is developed via optimizing the detector geometry and its optical surface, by selecting the reflective material and adopting dynode readout. This detector can meet our physics requirements with a positional non-uniformity of the output charge within 10% (with reference to the center of the scintillator), time resolution FWHM of similar to 2.2 ns, and dynamic range from 1 to 500 minimum ionization particles.
