Progress of the development of the ELI-NP GBS high level applications
The Gamma Beam System (GBS) is a high brightness LINAC to be installed in Magurele (Bucharest) at the newELI-NP (Extreme Light Infrastructure — Nuclear Physics) laboratory. The accelerated electrons, with energiesranging from 280 to 720 MeV, will collide with a high power laser to produce tunable high energy photons(0.2–20 MeV ) with high intensity (1013photons/s), high brilliance and spectral purity (0.1%BW), through theCompton backscattering process. This light source will be open to users for nuclear photonics and nuclear physicsadvanced experiments. Tested high level applications will play an important role in commissioning and operation.In this paper we report the progress and status of the development of dedicated high level applications. We alsopresent the results of the test on the FERMI LINAC of the electron trajectory control method based on DispersionFree Steering.
