Klapisch magnet: RF dipole for combining beams from 4 PSB rings for PS injection View of the 8 MHz beam deflecting magnet installed in the transfer fine between the CERN Booster and Proton Synchrotron to interleave successive bunches from the Booster's four rings

The r.f. dipole, designed to assemble beams from the four separate Booster rings appropriately for injection into the PS. The structure is resonant at the bunch frequency of 8 MHz. Currents at this frequency flowing in opposite directions in the top and bottom conductors create a magnetic field providing the correct vertical deflection to direct the bunches arriving at different times and angles from each ring in sequence along the horizontal axis towards the PS.
