%X We report on a novel, non-invasive method applying Thomson scattering to measure the evolutionof the electron beam energy inside a laser-plasma accelerator with high spatial resolution. Thedetermination of the local electron energy without altering the final beam state enabled the in-situdetection of the acting acceleration fields, in this Letter demonstrated in a plasma density rampvarying from (265 ± 119) GV/m to (9 ± 4) GV/m. The presented data shows excellent agreementwith particle-in-cell simulations. This method provides new possibilities for detecting dynamics ofplasma-based accelerators and their optimization.
