a, Measured energy modulation of e-pulse as a function of electron-THz delay for constructive interference of the E-fields entering the device and cancellation of B-fields. b, Corresponding beam deflection measured for constructively interfering of the B-fields, i.e. E-field cancellation scenario. (c) and (d): Time-dependent deflection diagram measured by varying the electron-THz delay in the B-field and E-field cancellation scenario, respectively. e, Measured shape of e-beam on MCP detector for maximum acceleration, deceleration and right and left deflection points plotted in one image. Intensity was normalized and image contrast was tuned in order to show the relative positions more clearly. This demonstration was performed using the Yb:KYW laser with ~2×0.5 µJ of THz radiation coupled into the device and a bunch charge of ~1 fC.
