A High-Energy and High-Intensity Inverse Compton Scattering Source Based on CompactLight Technology

An inverse Compton scattering source based on the CompactLight injector and capable of producing MeV gamma-rays with a brilliance several orders magnitude larger than existing sources is proposed. The can operate at bunch repetition rate 1 kHz, trains 50 bunches spacing 5 ns, giving maximum total flux 8.62 × 1011 photons/s. For normalised emittance 0.3 mm mrad, an average 1.85 1014 photons/(s mm2 mrad2 0.1%BW) could be obtained. A kW colliding laser was considered, corresponding to pulse energy mJ. Given electron beam up 300 provided by photoinjector, photon 2 Simulations were performed using RF-Track particle tracking software. Parametric scans used derive spot sizes maximising flux. accelerator optic components also determined from final focus design, which optimised for micrometer-level size interaction point. in order 1012 photons/s output range, proposed various applications, including X-ray imaging.
