  The Low Energy Beam Transport line (LEBT) for the Frankfurt Neutron Source (FRANZ) has been redesigned to accommodate a 60 keV proton beam. Driven by a CHORDIS ion source, operating at 35 kV, a newly designed electrostatic postaccelerator has beeen installed to reach the desired beam energy of 60 keV. Additional upgrades to the beamline include two steerer pairs, several optical diagnostics sections and an additional faraday cup. We present the results of beam commissioning up to the point of RFQ injection. Emittance measurements were performed to prepare matching to the RFQ and improve the beam dynamics model of the low energy beamline. Due to the successful operation of the beamline at 60 keV, retrofitting of the RFQ for the new energy has been initiated.
