  A high-pulse-current injector followed by a short high-gradient X-band linac is considered as a driver for a compact Inverse Compton Scattering source. We show that using a high-power ultrashort pulse laser operating in burst mode and a Fabry-Pérot enhancement cavity, X-rays with flux values over 1013 ph/s and photon energies up to MeV are achievable. The resulting high-intensity and high-energy X-rays allow for various applications, including cancer therapy, tomography, and nuclear waste management. A preliminary conceptual design of such a compact ICS source is presented, together with simulations of the expected performance.

  The interest for Very High Energy Electron (VHEE) radiotherapy (RT) for cancer treatment recently bloomed, given the present availability of high-gradient accelerator technology for compact, cost effective electron linacs in the 100-200 MeV energy range. Particularly promising is the so called FLASH high dose rate regime, in which cancer cells are damaged while healthy tissue is largely spared. VHEE beams are especially adapted for FLASH RT, given their penetration depth and the high beam current, needed to treat large deep seated tumors. In the CERN Linear Accelerator for Research (CLEAR) facility, a series of unique studies have been initiated on VHEE and FLASH RT issues, in collaboration with several multidisciplinary user groups. In this paper we briefly outline the activities and its main recent results, e.g. on localized dose deposition by beam focusing, and on chemical and biological test to clarify damage mechanisms. We then describe in details the dedicated systems and the techniques adopted - and in large part locally developed by the CLEAR team - in order to satisfy the user requirements, with particular attention to the crucial aspect of high dose rate dosimetry.
