221. BELLA: multi-GeV electron beam generation and outlook

Dr Wim Leemans (Lawrence Berkeley National Laboratory)

9/14/15, 11:00 AM

invited talk

Multi-GeV electron beam has been produced from a capillary discharge waveguide structure powered by the BELLA laser at LBNL. Comparison between simulation and experiment will be detailed and future prospects in plasma acceleration using petawatt class lasers will be given.

30. High Efficiency and High-Gradient Acceleration of Electrons and Positrons in a Plasma Wakefield Accelerator

Prof. Chandrashekhar Joshi (UCLA)

9/14/15, 11:30 AM

invited talk

Recent progress on high-gradient and high-efficiency electron and positron acceleration in a plasma wakefield accelerator at the FACET facility will be described. In the case of electrons, a high current drive bunch is used to produce an extremely nonlinear, high gradient wake in a meter-scale plasma. An appropriately placed trailing bunch containing a significant charge loads the wake and...

11. Beam manipulation with Velocity Bunching for PWFA applications

Riccardo Pompili (LNF)

9/14/15, 12:00 PM

invited talk

SPARC-LAB is exploring the PWFA scheme by using multi-bunch electron beam as driver to excite resonantly the plasma in a capillary discharge. Velocity bunching is used to generate the train of short (<100fs) bunches with the temporal spacing required to achieve the proper accelerating field and to accelerate the trailing witness bunch with low energy spread. Comparison between simulation...
