Drive beam recombination optimization at CTF3

The CLIC Test Facility (CTF3) installed at CERN has a scaled version of the CLIC design Drive-Beam Recombination Complex (DBRC). This complex is designed to recombine a long electron train into a shorter one but with increased bunch frequency and pulse current. A generic feedback algorithm to solve (quasi-)linear systems has been implemented in Matlab and it is used to optimize the process by tuning the energy of the incoming beam and steer the orbits in the different lines, as well matching the design dispersion. Current results and possible room for further optimization will be shown.
