Evaluation and comparison of trigger strategies for the SWGO

The Southern Wide-field Gamma-ray Observatory (SWGO) is a future TeV gamma-ray observatory to be built in Chile. The high-duty cycle experiment will consist of about 4000 water-Cherenkov tanks equipped with two photomultiplier tubes each. The available computational infrastructure will not be sufficient to handle all the raw data SWGO will produce. Therefore, to limit the computational requirements, it is necessary to develop a sophisticated trigger strategy. This trigger strategy reduces the amount of data while also ensuring its scientific quality. In this contribution, we present our developed framework to test and validate different trigger strategies. We came up with a metric for the trigger quality, allowing us to compare trigger strategies with each other. We present the developed tools and demonstrate their use.

Abstract

The Southern Wide-field Gamma-ray Observatory (SWGO) is a future TeV gamma-ray observatory to be built in Chile. The high-duty cycle experiment will consist of about 4000 water-Cherenkov tanks equipped with two photomultiplier tubes each. The available computational infrastructure will not be sufficient to handle all the raw data SWGO will produce. Therefore, to limit the computational requirements, it is necessary to develop a sophisticated trigger strategy. This trigger strategy reduces the amount of data while also ensuring its scientific quality. In this contribution, we present our developed framework to test and validate different trigger strategies. We came up with a metric for the trigger quality, allowing us to compare trigger strategies with each other. We present the developed tools and demonstrate their use.
