Using a high-power ultra-short pulse laser operating in burst mode in a Fabry-Pérot enhancement cavity, we show that outcoming photons with a total flux over 10¹³ and energies in the MeV range are achievable. The resulting high-intensity and high-energy photons allow various applications, including cancer therapy, tomography, and nuclear material detection. A preliminary conceptual design of such a compact ICS source and simulations of the expected performance are presented.
