Abstract: A tunable plasma-based energy dechirper has been developed at FLASHForward to remove thecorrelated energy spread of a 681 MeV electron bunch. Through the interaction of the bunch withwakefields excited in plasma the projected energy spread was reduced from a FWHM of 1.31% to 0.33%without reducing the stability of the incoming beam. The experimental results for variable plasma densityare in good agreement with analytic predictions and three-dimensional simulations. The proof-of-principledechirping strength of $1.8$ $ GeV/mm/m$ significantly exceeds those demonstrated for competing state-of-the-art techniques and may be key to future plasma wakefield-based free-electron lasers and high energyphysics facilities, where large intrinsic chirps need to be removed
