Description
Transverse stabilization of the beam in accelerators is crucial for optimizing any machine’s performance. The most common method for minimizing transverse beam jitter is the Balakin-Novokhatsky-Smirnov (BNS) damping technique. While this method has been successfully implemented worldwide, it has limitations in terms of beam quality preservation and acceleration efficiency, primarily because the accelerating structures are operated off-crest. In this work, we propose an alternative approach to induce the necessary energy spread while keeping the RF accelerating cavities operated on-crest. We applied this approach to the design of the Future Circular Collider (FCC) linacs, which are designed to achieve a beam energy of up to 20 GeV. From simulations we expect to maintain the transverse beam jitter increase below few percent compared to the initial one in a full length of about 1 km, optimizing the transverse beam quality and maximizing the energy efficiency. This method is general and can be applied to any accelerator.
