An attractive approach towards femtosecond and sub-femtosecond range consists in using terahertz-driven devices, which offer a good combination of high frequency and high gradient-gradients of GV/m have been demonstrated in split ring resonator using pulse created by rectifying ultrashort laser pulses. We present results obtained from a beam experiment at the VELA facility at Daresbury laboratory. We tested a planar resonator derived from the geometry of a split ring resonator with an aperture for the beam of 20 um. PB - JACoW Publishing CP - Geneva, Switzerland ER -
