Description
CTAO North will consist of four Large Size Telescopes (LSTs), designed to detect very low-energy gamma rays. Given the limited lifespan of current cameras, new prototypes are being developed for the next generation of LSTs. The LST AdvCam, based on silicon photomultipliers, digitises signals from its nearly 8,000 pixels at 1 GHz, generating a volume of data that requires highly efficient trigger systems, since the vast majority of images correspond simply to Night Sky Background, not interesting for astrophysical analysis. Unlike the previous camera, AdvCam performs digitisation before triggering, allowing advanced algorithms to be applied to improve sensitivity at lower energies. In this presentation, we analyse different types of algorithms, from the simplest, such as ORs, to Convolutional Neural Networks, and their final implications for the telescope response.
