Experimental observation of energy modulation in electron beams passing through terahertz dielectric wakefield structures.

چکیده
We report the observation of a strong wakefield induced energy modulation in an energy-chirped electron bunch passing through a dielectric-lined waveguide. This modulation can be effectively converted into a spatial modulation forming microbunches with a periodicity of 0.5-1 ps and, hence, capable of driving coherent terahertz radiation. The experimental results agree well with theoretical predictions.

Enhanced tunable narrow-band THz emission from laser-modulated electron beams
Abstract We propose and analyze a scheme to generate enhanced narrow-band terahertz (THz) radiation through down-conversion of the frequency of optical lasers using laser-modulated electron beams. In the scheme the electron beam is first energy modulated by two lasers with wave numbers k1 and k2, respectively. After passing through a dispersion section, the energy modulation is converted to den...
متن کاملObservation of acceleration and deceleration in gigaelectron-volt-per-metre gradient dielectric wakefield accelerators
There is urgent need to develop new acceleration techniques capable of exceeding gigaelectron-volt-per-metre (GeV m(-1)) gradients in order to enable future generations of both light sources and high-energy physics experiments. To address this need, short wavelength accelerators based on wakefields, where an intense relativistic electron beam radiates the demanded fields directly into the accel...
متن کاملWakefield-based Dechirper Structures for Elbe
The efficient reduction of the pulse length and the energy width of electron beams plays a crucial role in the generation of short pulses in the range of sub-picoseconds at future light sources. At the radiation source ELBE in DresdenRossendorf short pulses are required for coherent THz generation and laser-electron beam interaction experiments such as X-ray Thomson scattering. Energy dechirpin...
متن کاملPassive Momentum Spread Compensation by a “wakefield Silencer”*
We report the observation of de-chirping of a linearly chirped (in energy) electron bunch by its passage through a 5 cm long dielectric loaded waveguide structure. The experiment was conducted at the ATF facility at BNL according to a concept dubbed the "wakefield silencer" originally developed at the ANL AATF [1] which involves defining the electron bunch peak current distribution and selectin...
متن کاملDielectric wakefield acceleration of a relativistic electron beam in a slab-symmetric dielectric lined waveguide.
We report first evidence of wakefield acceleration of a relativistic electron beam in a dielectric-lined slab-symmetric structure. The high energy tail of a ∼60 MeV electron beam was accelerated by ∼150 keV in a 2 cm-long, slab-symmetric SiO2 waveguide, with the acceleration or deceleration clearly visible due to the use of a beam with a bifurcated longitudinal distribution that serves to app...
