U.) ; Vretenar, Maurizio (CERN) ; Zimek, Zbigniew (Warsaw, Inst. Phys.)
Project seeks to tackle the shipping industry’s most pressing problem, its large-scale emissions of SOx, NO and PM, by developing a hybrid exhaust gas-cleaning technology that combines an EB accelerator with improved wet-scrubbing technology. It is unique - in a single technological system - addresses all three types of emissions simultaneously. [...]

Plasma accelerators support accelerating fields of 100's of GV/m over meter-scale distances and routinely produce femtosecond-scale, multi-kA electron bunches. The so called Trojan Horse underdense photocathode plasma wakefield acceleration scheme combines state-of-the-art accelerator technology with laser and plasma methods and paves the way to improve beam quality as regards emittance and energy spread by many orders of magnitude.
