  The ERC grant COXINEL aims at demonstrating experimentally Free Electron Laser (FEL) amplification with electrons generated by laser plasma acceleration (LPA). Because of the still limited electron beam performance (especially energy spread and divergence) in view of the FEL requirements, the electron beam transfer line has been specifically designed with adequate diagnostics and strong focusing variable strength permanent magnet quadrupoles, an energy de-mixing chicane and second set of quadrupoles for further dedicated focusing in the FEL interaction region, in a U20 in-vacuum undulator, enabling to operate at 200 nm with a 180 MeV electron beam. The first observation and transport of electrons in the COXINEL line is presented here.

  The THOMX facility is a compact X-Ray source based on the Compton back scattering aiming at a flux of 1011 to 1013 ph/s in the range of energy from 40 to 90 keV. Due to the compactness and the expected stability of this machine, high requirements are set for all magnets in terms of design and manufacturing. First, the design optimization of the magnets is presented, leading to high performance in terms of harmonics. Issues regarding the cross-talk between quadrupole and sextupole fields are then discussed.
