ELI-NP is a linac based gamma-source under construction in Magurele (RO) by the European consortium EuroGammaS led by INFN. Photons with tunable energy (from 0.2 to 19.5 MeV) and with unprecedented intensity and brilliance will be produced by Compton back-scattering between a high quality electron beam (up to 740 MeV), and a 515 nm intense laser pulse. In order to increase the gamma photon flux, the accelerator will operate in multi-bunch at 100 Hz repetition rate, with 32 bunches separated by 16 ns. Three S-band (2856 MHz) RF power plants will feed two room temperature Travelling Wave (TW) structures, a 1.6 cell Standing Wave (SW) S-band gun (which has been manufactured by means of a new technique based on clamped gaskets without brazing) and two SW RF deflectors for longitudinal beam diagnostics. Ten C-band (5712 MHz) RF power plants will feed 12 TW high-order-modes (HOM) damped structures. In this paper, we review the whole ELI-NP RF architecture including the Low Level RF (LLRF) system.

FERMI has reached its nominal performance on both FEL lines, FEL-1 (12 eV to 62 eV) and FEL-2 (62 eV to 310 eV). After a brief overview of the activities with users, we will describe plans for LINAC , FEL and beamline upgrades for 2016-2018 and beyond. This includes EEHG schemes for FEL-2.

The ELI-NP GBS is a high intensity and monochromatic gamma source under construction in Magurele (Romania). The design and construction of the Gamma Beam System complex as well as the integration of the technical plants and the commissioning of the overall facility, was awarded to the Eurogammas Consortium in March 2014. The delivery of the facility has been planned in for 4 stages and the first one was fulfilled in October 31st 2015. The engineering aspects related to the delivery stage 1 are presented.

This paper reports on the final design and the work in progress on the STAR project (IPAC2014:WEPRO115), which is under construction at the Univ. of Calabria (Italy). The project is devoted to the construction of an advanced Thomson source of monochromatic tunable, ps-long, polarized X-ray beams, ranging from 40 up to 140 KeV . At present the buildings and main plants have been completed as the acquisition of main components: the RF photo-injector, the accelerating section, laser systems for collision and photo-cathode, RF Power Source and magnets are ready to start installation and site acceptance tests. The design of laser lines is complete and simulated by ZEMAX, aiming to minimize energy losses, optical distortions and providing a tunable experimental setup as well. The RF power network is close to be tested, it's based on a 55MW (2.5us pulse) S-band Klystron driven by a 500kV Pulse Forming Network based modulator and a Low Level RF system, running at 100 Hz. The Control System is been designed using EPICS and allows to manage easily and fastly each machine parameter. We expect to start commissioning the machine by the end of 2016 and obtain the first collisions within the first part of 2017.
