Description
In recent years, Laser Plasma Acceleration (LPA) has become a promising alternative to
conventional RF accelerators. However, so far, it has only been theoretically shown that generating
polarized LPA beams is possible. The LEAP (Laser Electron Acceleration with Polarization)
project at DESY aims to demonstrate this experimentally for the first time, using a pre-polarized
plasma target.
The electron polarization will be measured with photon transmission polarimetry, which makes use
of the production of circularly polarized bremsstrahlung during the passage of the electron beams
through a suitable converter target. The photon polarization is then measured with the aid of
transmission asymmetry arising from reversing the magnetization direction of an iron absorber.
In this contribution an overview of the LEAP project is presented, detailing the generation of the
polarized electron beams along with the design and simulation studies of the polarimeter.
