The JSNS2 experiment aims to search for sterile neutrinos with Δm2 near 1eV2. A 3 GeV J-PARC proton beam incident on a mercury target produces an intense neutrino beam from muon decay at rest which oscillates to anti-electron neutrinos. The JSNS2 detector is located at 24 m baseline from the target. The detector has a fiducial volume of 17 tons filled with GdLS, that efficiently can detect anti-electron neutrinos via the inverse beta decay reaction followed by a gamma signal from the captured neutron on Gd. The trigger to take sterile neutrino events efficiently has been implemented at JSNS2. In this presentation, the trigger scheme for sterile neutrino at the JSNS2 experiment will be described.
