Description
We present a linear chirp control approach consisting of transverse deflecting cavities and negative-identity drift sections. While the beamline supports both positive and negative chirp manipulation, we focus on operation that drives the beam toward a large positive chirp for applications such as broadband radiation generation and Balakin-Novokhastky-Smirnov damping for structure wakefield acceleration. Emittance growth in this beamline is analyzed with an emphasis on second-order and space charge effects. Based on the identified sources, we propose a design that preserves beam quality while imparting or correcting a large chirp. In addition, sensitivity to cavity phase and amplitude jitter is evaluated, and the resulting impact on beam position and chirp is characterized. These results establish design guidelines and practical tolerance levels for stable operation.
