Design Study of a Dedicated Beamline for THz Radiation Generation at the SPARC Linac
Boscolo, Manuela
A feasibility study for a dedicated beamline for a THz radiation source at SPARC is discussed here. Two phases are foreseen for the THz radiation generation beamline. In the first phase of operation the SPARC electron beam will be transported through a dogleg and then delivered to a THz radiator, allowing a full characterization of the THz radiation.
In the second phase a magnetic compressor with negative R56 will be implemented in the dogleg, allowing exotic experiments with THz radiation produced by comb beams. A radiofrequency electron gun followed by a compressor can generate trains of THz sub-picosecond electron pulses by illuminating the photocathode with a comb laser pulse. This structure of the beam can be used to produce coherent radiation. The quality of the coherent spectrum emitted by a comb beam is tightly connected to the electron micro-bunches lengths and to micro-pulses inter-distance.
