Implementation of the IceTop7HG trigger in the IceCube Neutrino Observatory

A new trigger, IceTop7HG, was developed and implemented in the IceCube Neutrino Observatory at the South Pole, starting with the 2023 data-taking season. This new trigger is expected to capture inclined cosmic-ray air-shower events with higher efficiencies than the standard triggers. As IceTop, the surface detector of IceCube, is being upgraded with additional instruments like radio antennas, the new trigger will increase the statistics for combined detection of inclined air showers. Low-energy cosmic rays are a major source of background in this trigger. Hence, a filter to differentiate inclined high-energy air showers from the background is being developed.
