Even though, it is still very challenging because the energy jitter and energy spread of the-state-of-the-art LPAs are not small enough. There have been proposals, which are successful to suppress the energy jitter and energy spread simultaneously by implementing magnetic chicane together with active dechirper, for relatively low charge conditions (e.g., tens of pC). However, this method is not very effectivewhen the bunch charge becomes an order of magnitude higher due to the heavy beam loading. In this paper, we present a novel method which can suppress the energy jitter and reduce the energy spread simultaneously even with heavy beam loading. Preliminary particle-in-cell (PIC) simulations showed that such a design can reduce the energy jitter and energy spread of the 500 pC bunches from ±2\% and 2.39\% to less than 0.33\% and 0.8\%, respectively, with high transmission efficiency (>89\%).
