N2  - In­tense ion beams with small phase space oc­cu­pa­tion (high bril­liance) are manda­to­ry to keep beam loss­es low in high cur­rent in­jec­tor ac­cel­er­a­tors like those planned for FAIR. The low en­er­gy beam trans­port from the ion source to­wards the linac has to keep the emit­tance growth low and has to sup­port the op­ti­miza­tion of the ion source tune. The Frank­furt Neu­tron Source Fa­cil­i­ty FRANZ is cur­rent­ly under con­struc­tion. An in­tense beam of pro­tons (2 MeV, 200 mA) will be used for neu­tron pro­duc­tion using the Li7(p,n)Be7 re­ac­tion for stud­ies of the as­tro­phys­i­cal s-pro­cess. A col­li­ma­tion chan­nel, which can be ad­just­ed to allow the trans­port of beams with a cer­tain beam emit­tance, is an ideal tool to op­ti­mize the ion source tune in terms of beam bright­ness. There­fore a col­li­ma­tion chan­nel in the Low En­er­gy Beam Trans­port sec­tion will be used. Through de­fined aper­tures and transver­sal phase space ro­ta­tion using fo­cus­ing solenoids the beam halo as well as un­want­ed H2+ and H3+ frac­tions will be cut. The­o­ret­i­cal stud­ies which were car­ried out so far and a first de­sign of the setup will be pre­sent­ed.
