  The op­tics sim­u­la­tion group at HZB is de­sign­ing a multi-turn en­ergy re­cov­ery linac -based light source. Using the su­per­con­duct­ing Linac tech­nol­ogy, the Femto-Sci­ence-Fac­tory(FSF) will pro­vide its users with ul­tra-bright pho­ton beams of angstrom wave­length. The FSF is in­tended to be a multi-user fa­cil­ity and offer a va­ri­ety of op­er­a­tion modes. The dri­ver of the fa­cil­ity is a 6GeV mul­ti­turn en­ergy re­cov­ery linac with a split linac. In this paper we com­pare dif­fer­ent schemes of beam ac­cel­er­a­tion: a di­rect in­jec­tion scheme with ac­cel­er­a­tion in a 6 GeV linac, a two-stage in­jec­tion with ac­cel­er­a­tion in a 6 GeV linac, and a multi-turn (3-turn) scheme with a two-stage in­jec­tion and two main 1 GeV linacs. The key points were costs and beam break up in­sta­bil­ity.
