Title: Towards a Free Electron Laser using laser plasma acceleration
Abstract: In the last decade, new accelerating techniques such as laser-plasma acceleration (LPA), have made significant progress. However, despite acceleration over extremely short distance, the electron beam properties of these new sources remain a bottleneck for direct application of the LPA to lightsources. The inherent large energy spread and divergence, with respect to conventional accelerators, are recognised to be one of the most limiting parameters for LPA applications.
We report here on the undulator spontaneous emission measured after the 10-m long COXINEL line. The measured undulator radiation provides an insight on the electron beam properties. Original strategies have been elaborated to control the electron beam properties.
