The PITZ fa­cil­i­ty is es­tab­lished for the de­vel­op­ment and test­ing of elec­tron sources for FELs like FLASH and the Eu­ro­pean XFEL. The fa­cil­i­ty has been up­grad­ed dur­ing the shut­down start­ing in sum­mer 2007 to ex­tend the ca­pa­bil­i­ty of the fa­cil­i­ty to pro­duce and char­ac­ter­ize low emit­tance elec­tron beams. The up­grad­ed setup main­ly in­cludes a photo cath­ode L-band RF gun with solenoid mag­nets for space charge com­pen­sa­tion, a post ac­cel­er­a­tion boost­er cav­i­ty and sev­er­al di­ag­nos­tic sys­tems. The di­ag­nos­tic sys­tems con­sist of charge and beam pro­file mon­i­tors, emit­tance mea­sure­ment sys­tems and spec­trom­e­ters with re­lat­ed di­ag­nos­tics in dis­per­sive arms after the gun and the boost­er cav­i­ties. RF gun op­er­a­tion with an ac­cel­er­at­ing gra­di­ent of 60 MV/m at the cath­ode is re­al­ized with this setup. A new photo cath­ode laser sys­tem with broad­er spec­tral band­width was in­stalled for op­ti­miz­ing the tem­po­ral dis­tri­bu­tion of the laser puls­es re­gard­ing to elec­tron beam prop­er­ties. Ex­per­i­men­tal re­sults with this setup demon­strat­ed very high elec­tron beam qual­i­ty as re­quired for the pho­toin­jec­tor source of the Eu­ro­pean XFEL. In this con­tri­bu­tion, the PITZ fa­cil­i­ty setup in year 2008-2009 will be pre­sent­ed.
