  The heavy ions low en­er­gy beam trans­port line (LEBT) of Spi­ral2 built at LPSC Greno­ble is fully op­er­a­tional since the be­gin­ning of 2010. This LEBT has been cal­cu­lat­ed and de­signed to hold per­ma­nent­ly 15 mA of mul­ti­charged ions ex­tract­ed from the source at 60 kV. PHOENIX V2 ECRIS is present­ly in­stalled on the LEBT and first tests start­ed few months ago: A re­li­able beam of 1 mAe of O6+ beam at 45 kV has al­ready been ob­tained for a long pe­ri­od with a very good trans­mis­sion, and good re­pro­ducibil­i­ty. Tests con­tin­ue with an op­ti­miza­tion of Ar12+ beam per­for­mance. The promis­ing re­sults of these first runs, par­tic­u­lar­ly emit­tance mea­sure­ments, pro­files and op­ti­miza­tion of charge op­tics will be pre­sent­ed along. The ECRIS Phoenix V2 and dif­fer­ent equip­ments in­stalled on this line (vac­u­um sys­tem, optic el­e­ments, di­ag­nos­tics…) will be de­scribed. The fu­ture pro­gram and planned im­prove­ments on the LEBT will be also dis­cussed in this paper.

  The COMIC dis­charge cav­i­ty is a very ver­sa­tile tech­nol­o­gy. We will pre­sent new re­sults and de­vices that match new ap­pli­ca­tions like: molec­u­lar beams, ultra com­pact beam line for de­tec­tors cal­i­bra­tions, quartz source for on-line ap­pli­ca­tion, high volt­age plat­form source, sput­ter­ing /as­sis­tance broad beams and fi­nal­ly, a quite new use, high en­er­gy multi¬-beam pro­duc­tion for sur­face ma­te­ri­al mod­i­fi­ca­tions. In more de­tails, we will show that the tiny dis­charge of COMIC can main­ly pro­duce molec­u­lar ions (H3+). We will pre­sent the pre­lim­i­nary op­er­a­tion of the fully quartz ISOL­DE COMIC ver­sion, in col­lab­o­ra­tion with IPN-Ly­on, we will pre­sent a first ap­proach for a slit ex­trac­tion ver­sion of a three cav­i­ty de­vice, and after dis­cussing about var­i­ous ex­trac­tion sys­tems on the multi dis­charge de­vice (41 cav­i­ties) we will show the low en­er­gy broad beam (2 KV) and high en­er­gy mul­ti-beams (10 beams up to 30 KV) pro­duc­tions. We will spe­cial­ly pre­sent the dif­fer­ent ex­trac­tion sys­tems adapt­ed to each ap­pli­ca­tion and the beams char­ac­ter­is­tics which are strong­ly de­pen­dent on the volt­age dis­tri­bu­tion of an ac­cel-ac­cel two elec­trodes ex­trac­tion sys­tem.
