Description
Large-Sized Telescope target low-energy gamma rays, starting at 20 GeV. New silicon photomultiplier (SiPM) camera detect twice as much light as photomultiplier tube ones. This reduce detectable energy threshold, but separating signal from background remains a challenge. The SiPM-camera pixels are about 1/4 of the current camera allowing for higher-detail images which can be captured by AI methods.
State-of-the-art SiPMs offer endless lifespan, robustness, low noise, crosstalk, and power consumption. Ideal for long-term, low-maintenance cameras. This work details telescope simulation with new camera, performance, and introduces low and high-level triggers. Early signal digitization enables sophisticated low-level trigger with density-based clustering algorithm. Convolutional neural network serves as high-level trigger and analysis.
