Abstract
We are developing a wide field-of-view Cherenkov telescope with large dimensional refractive lens for sub-100 GeV to TeV gamma ray astronomy. A prototype of the refractive telescope with a camera composing of 48 PMTs and the front-end electronics is designed, assembled, and tested to demonstrate the feasibility of the concept. In this work, we report some preliminary results on the detection of high energy Cosmic Rays (CRs) using the prototype telescope which was operated in coincidence with a scintillator detector array at the Yangbajing Observatory in Tibet.The prototype telescope can achieve a $15^{\circ} \times 11^{\circ}$ FoV and a ${\sim}0.8^{\circ}$ angular resolution which is suitable to take certain Cherenkov images for air showers.
