  ELI-NP gamma beam sys­tem (GBS) is a linac based gamma-source in 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 in­ten­sity and bril­liance be­yond the state of the art, will be pro­duced by Comp­ton back-scat­ter­ing be­tween a high qual­ity elec­tron beam (up to 740 MeV) and an in­tense laser pulse at 100 Hz rep­e­ti­tion rate. Pro­duc­tion of very in­tense pho­ton flux with nar­row band­width re­quires multi-bunch op­er­a­tion and laser re­cir­cu­la­tion at the in­ter­ac­tion point. In this paper, the main tech­no­log­i­cal de­vel­op­ments car­ried out by the Eu­roGam­maS con­sor­tium for the gen­er­a­tion of the ELI-NP gamma beam will be de­scribed with a spe­cial em­pha­sis on the elec­tron linac tech­nol­ogy, such as: RF-gun and C-band ac­cel­er­at­ing struc­tures de­sign fab­ri­ca­tion and tests; low level RF (LLRF) and syn­chro­niza­tion sys­tems spec­i­fi­ca­tions and de­vel­op­ment. Fi­nally, the laser re­cir­cu­la­tion ap­pa­ra­tus de­sign is briefly de­scribed and first re­sults re­ported.

  Ad­vanced di­ag­nos­tics tools are cru­cial in the de­vel­op­ment of plasma-based ac­cel­er­a­tors. Ac­cu­rate mea­sure­ments of the beam qual­ity at the exit of the plasma chan­nel are manda­tory for the op­ti­miza­tion of the plasma ac­cel­er­a­tor. 6D elec­tron beam di­ag­nos­tics will be re­viewed with em­pha­sis on emit­tance mea­sure­ment, which is par­tic­u­larly com­plex due to the pe­cu­liar­ity of the emerg­ing beams.
