Beam asymmetry compensation at DESY photoelectron guns

Quadrupole fields are considered as an option for beam asymmetry compensation for L-band photoelectron guns used at DESY. The quadrupoles dedicated for the installation at a gun coupler region have three designs. The first two designs were installed and tested with photoelectron beam. The designs of...

Summary:Quadrupole fields are considered as an option for beam asymmetry compensation for L-band photoelectron guns used at DESY. The quadrupoles dedicated for the installation at a gun coupler region have three designs. The first two designs were installed and tested with photoelectron beam. The designs of the quadrupoles and experiments results are presented.
