Relativistic magnetic reconnection experiment at CLF TAW

A 5-week experiment using the Central Laser Facility’s VULCAN Target Area West (TAW) laser has just come to an end.  The experiment explored the evolution of magnetic fields formed between two high intensity laser pulses at the surface of a solid target by probing the dynamic fields with a broad energy spread proton beam.  TAW is the perfect facility for these studies providing multiple high intensity pulses for generation of the reconnection fields and the probing proton beam.  In addition to study of the magnetic fields, angularly resolved measurements of the electron beam accelerated from the reconnecting region have allowed us to observe directional, non-thermal components to the energy spectra.  Further analysis of this in combination with the proton probing images will help us to understand the details of this highly dynamic process.

Publication on density down-ramp injection in a beam driven plasma wakefield accelerator

Alberto Martinez de la Ossa, based at DESY, Hamburg, lead a recent publication describing an impressive theoretical study on high quality electron beam injection in a electron beam driven plasma wakefield ( This mechanism will be experimentally studied in the FLASHForward project, a unique experiment in the world which aims to drive a free-electron laser from a plasma accelerated electron beam.
