Abstract

The detection efficiency of the atmospheric Cerenkov flashes in searching for very high energy (VHE) gamma-ray sources using the multichannel imaging cameras (MIC) are compared for various technique. Here the detection efficiency is regarded as the time needed for gamma-ray source detection with the preset flux at a certain confidence level. The shorter the time the higher the efficiency.

The Monte Carlo simulation of the flashes detection process by MIC has been used for the comparison of various observational methods. The analysis has shown that the tracking of the source followed by the background tracking is the most efficient. Scanning and off-axis observations are 1.5–2.0 times less efficient.
