Search for GeV Gamma-Ray Bursts with the ARGO-YBJ Detector in Scaler Mode

摘要：

The ARGo-YBJ experiment is a full coverage atray made of Resistive Plate Chambers(RPCs)operated in streamermode tO detect the extensive array showers(EASs)．With large field of view(>2sr)and high duty cycle(>90％),the ARGo-YBJ detector is the right ground-based apparatus to detect VHE GRBs,while the high altitude (4300 m a．s．1)and scalerworking mode enable it to detect GRBs in the GeV region as high energy follow-up observation of satellites such as SWIFT.If a GRB signal is detected,the four scaler channels,which correspond to different energy thresholds,can provide furtherinformation on the energy spectrum and its cut-off.More than 40 SWIFT GRBs were in ARGO-YBJ field of view,nosignificant excess was detected till now．
