The dead time of this system is 0.16 s and the loss was measured to be less than 1%. By performing the online clustering algorithm on the simulated data, the trigger efficiency for the primary mode IMG ALIGN="MIDDLE" ALT="${K}-{L}\to {\pi } {0}\nu \bar{\nu }$" SRC="JPCS-1526-1-012034-ieqn1.gif" is estimated to be 99.6%. ?
