abstract = {{The measurement of the bunch length can better realize the monitoring of the beam, because the bunch length is one of the important longitudinal parameters of the beam. In this paper, a new single-cavity bunch length monitor is proposed, whose coupling structures consist of two kinds of filters. One is a low pass filter, the other is a band pass filter. The coaxial low-pass filter is used to couple out lowfrequency signals, and the band-pass filter is used to couple higher-frequency signals. According to the beam characteristics of the National Synchrotron Radiation Laboratory (NSRL)based on the tunable infrared laser energy chemistry research large-scale experimental device (FELiChEM), we perform simulation in CST. The simulation results show that the monitor can measure the bunch length of the FELiChEM device very well, and the simulation measurement error is less than 2%.}},
