Abstract :
In this paper we report the status of the High Intensity γ-ray Source facility (HIγS) based on intra-cavity Compton back-scattering inside the OK-4/Duke storage ring FEL (SR FEL). The HIγS is generating beams of γ-rays with tuneable energy from 1.8 MeV to 58 MeV and total average flux up to 5108 γ-rays per second. The γ-ray beam is mono-chromatized by on-axis collimator to energy spread as low as 0.2% RMS. The HIγS facility generated in excess of 2,000 hours of the γ-ray beam time for nuclear physics user program. We discuss the incoming up-grades of the facility in next five years including the installation of the OK-5 FEL with controllable polarisation and the full-energy booster-injector
