description: The next generation of Gamma-ray observatory - Cherenkov Telescope Array (CTA) - aims at improving the detection capabilities at a broad energy range of the gamma-ray spectrum by a factor of 10 in sensitivity. The FlashCam camera is one of the camera types mounted on the medium-sized telescopes (MST) of CTA, responsible for the observation of the core energy range between 150 GeV and 5 TeV. The first part of this thesis assumed the task of verifying the trigger system of FlashCam. Studies of the trigger efficiency and night-sky background light trigger response were performed, whilst also improving the Monte-Carlo description of the detector. The second part was dedicated to the research of the fluorescence light detection capabilities of the full 25 FlashCam-MST sub-array using simulations. A trigger logic was developed, which allows the detection of air showers with primary energies higher than 1 PeV through their fluorescence emission. The effective area of this detection method was determined and the angular resolution using a shower axis reconstruction calculated. The combination of these individual studies allowed the estimation of the sensitivity on point-like gamma-ray sources emitting in the energy range above 1 PeV.
