Slice energy spread is one of the key parameters of beam brightness for free electron laser optimizations, but its measurement is not straightforward. Two recent studies at high energy (>100 MeV) photoinjectors at SwissFEL and European XFEL have measured much higher slice energy spread than simulations, leading to the debate of necessity of laser heaters. In this report, we will show a new method of measuring slice energy spread in the low energy (~20 MeV) photoinjector at PITZ, and the results are much closer to simulations.
