The Topo-trigger: A new stereo trigger for lowering the energy threshold of IACTs
Abstract
The purpose of the hardware presented in this contribution is to decrease the energy threshold of the MAGIC telescopes without significantly increasing the data acquisition rate. To achieve this purpose, we developed an additional level of trigger that relies on the location in both MAGIC cameras where the trigger is issued to rule out accidental events. This allows to decrease the Discriminator Threshold (DT), which results in a reduction of the energy threshold of the instrument. We simulated the Topo-trigger concept using the standard MAGIC Monte Carlo (MC) and tested it with real telescope data. In this paper we show the concept and results of these tests.
