Before dedicated data taking in the first-half of 2021, we performed a commissioning run for 10 days in June 2020. Using the data obtained in this commissioning run, in this paper, we present an estimate of the correlated background which imitates the ?¯e signal in a sterile neutrino search. In addition, in order to demonstrate future prospects of the JSNS2 experiment, possible pulse shape discrimination improvements towards reducing cosmic ray induced fast neutron background are described.
