Summary of working group 1: Electron beams from plasmas

Summary, Working Group 1: Electron guns and injector designs

We summarize the proceedings of Working Group 1 of the 2005 Energy Recovery Linac (ERL) Workshop. The subject of this working group, the electron gun and injector design, is arguably the most critical part of the ERL as it determines the ultimate performance of this type of accelerators. Working Group 1 dealt with a variety of subjects: The technology of DC, normal-conducting RF and superconduc...

Summary Report of Working Group on Equipment and Facilities: Stable Beams and Gamma Beams

Stable and photon beam experiments address scientific questions of paramount importance for stellar evolution and nucleosynthesis: Where are the elements produced that life depends on (carbon, nitrogen, oxygen)? How do stars evolve? Where are 50% of the elements beyond iron produced? Are there nuclear signatures to probe the core of stars, e.g., CNO neutrinos for probing the solar core metallic...

Alternate Scenarios Working Group Summary

Heavy flavours: working group summary

Production and fragmentation of heavy quarks is one of the most dynamical fields of research in QCD precision tests. There is an active interplay between experimental analysis and theoretical developments in this area. The aim of the working group was to discuss the relevant experimental and theoretical results that became available or updated since the previous DIS workshop in 2008. They are s...

Self-guiding electromagnetic beams in relativistic electron–positron plasmas

Nonlinear interaction of an intense electromagnetic (EM) beam with relativistically hot electron–positron plasma is investigated by invoking the variational principle and numerical simulation, resting on the model of generalized nonlinear Schrödinger equation with saturating nonlinearity. The present analysis shows the dynamical properties including the possibilities of trapping and wave-breaki...
