Abstract
In January 2007, King Abdulaziz University, Jeddah (21.5o N; 39.2o E; 14.8 GV), Saudi Arabia, installed a single channel muon detector for monitoring and studying the variations of the cosmic ray (CR) muons. Brief description of the developed detector will be presented. A few results obtained by the detector so far will be given and discussed. These include the impact of the atmospheric pressure and temperature, the daily variations, the responses of the detector to transit and long term of the solar disturbances. Performances of the detector were compared with the King Abdulaziz city for science and technology (KACST) muon detector installed in Riyadh Saudi Arabia and with the Oulu neutron monitor at Oulu and showed comparable results.
•Cosmic ray muon detector was installed at Jeddah (cut off rigidity Rc = 14.8GV) Saudi Arabia.•One of the main goal of this detector is to investigate CR correlations with solar activity and atmospheric phenomena.•The detector performance was tested and showed comparable results to other detectors.•Measurments from the detector were presented and compared with other detectors.•Short periodicities of the CR recorded by the detector were and found to be in good agreement with those reported by different researchers.
