Observation of a hot high-current electron beam from a self-modulated laser wakefield accelerator.
A highly relativistic electron beam produced by a 50 TW laser-plasma accelerator has been characterized by photonuclear techniques. The beam has large divergence that increases with plasma density. The electron yield also increases with plasma density and reaches up to 4x10(11) electrons ( >10 MeV), with beam current approaching the Alfvén limit. Effective electron temperatures exceeding 8 MeV ...

We use local quark-hadron duality to estimate the purely nonperturbative soft contribution to the γ * p → ∆ form factors. Our results are in agreement with existing experimental data. We predict that the ratio G * E (Q 2)/G * M (Q 2) is small for all accessible Q 2 , in contrast to the pQCD expectations that G * E (Q 2) → −G * M (Q 2).
متن کاملHigh Voltage, High Current, Long Pulse Electron Beam Injector for Darht
An injector design for the long pulse option for the second axis of the Dual-Axis Radiographic Hydrotest Facility (DARHT) has been studied. This design is based on the LBNL Heavy Ion Fusion Injector technology. The proposed injector consists of a single gap diode extracting electrons from a thermionic source and powered through a high voltage ceramic insulator column by a Marx generator. The ke...
متن کاملA High Current, Short Pulse, Rf Synchronized Electron Gun for the Stanford
For the generation of intense single and multiple bunches of electrons (>8 nc per bunch) for accelerator studies at SLAC, a high peak current photoemission electron gun has been developed. A gallium arsenide photocathode is illuminated by the optical beam from a frequency doubled, actively mode-locked and Q-switched Nd:YAG laser. The mode-locked optical pulses are of variable, sub-nanosecond wi...
متن کاملUltrashort-pulse relativistic electron gun/accelerator
Laser driven plasma waves have up to now been considered exclusively as second stage accelerators. Conventional finacs are used in this case as the first stage of acceleration to inject MeV electrons into the plasma. This paper shows it to be advantageous to instead use laser wake fields in the first stage for greater simplicity and better emittance. The concept presented makes this possible wi...
