	The high brightness electron LINAC of the Compton Gamma Source at the ELI Nuclear Physics facility in Romania is accelerating a train of 32 bunches with a nominal charge of 250 pC and nominal spacing of 16 ns. To achieve the design gamma flux, all the bunches along the train must have the designed Twiss parameters. Beam sizes are measured with optical transition radiation monitors, allowing a quadrupole scan for Twiss parameters measurements. Since focusing the whole bunch train on the screen may lead to permanent screen damage, we investigated non-conventional scans such as scans around a maximum of the beam size or scans with a controlled minimum spot size. This paper discusses the implementation issues of such a technique in the actual machine layout.

	The ELI-NP GBS is an high spectral density and monochromatic gamma ray source based upon the inverse Compton scattering effect now under construction in Magurele. Its relevant specifications are brilliance higher than 10²¹, 0.5% monochromaticity and a 0.2-19.5 MeV energy tunability. Strong requirements are set for the electron beam dynamic: the control of both the transverse normalized emittance and the energy spread to optimize the spectral density and guarantee the mono chromaticity of the emitted radiation. On this basis the RF Linac optimization has been performed for the designed energy range; a sensitivity analysis of the machine to possible jitters, errors and so on has been also performed, the simulations results hare here presented.

	The ELI-NP-GBS is an advanced source of up to 20 MeV Gamma Rays based on Compton back-scattering. We present the investigation of the production of the ELI-NP gamma photon beam generated by Compton back-scattering between the electron bunch accelerated in the linac and the laser pulse. At the interaction point (IP), the Compton backscattering properties, as spectral flux, brilliance and polarization are evaluated by the Klein-Nishina cross section. The gamma beam produced has energy ranging from 0.2 to 19.5 MeV and bandwidth of 0.5%. In order to define the optimal layout and evaluate the performances of the collimation and detection systems, a detailed Monte Carlo simulation activity has been carried out taking into account possible jitters and errors.
