  A dedicated proton injector for FAIR (the pLinac) is presently under construction at GSI Darmstadt. This accelerator is designed to deliver a beam current of up to 70 mA with a final energy of 68 MeV for the FAIR anti-proton program. For the commissioning of the pLinac a movable beam diagnostics test bench will be used to characterize the proton beam at different locations during the stepwise installation. The test bench will consist of all relevant types of diagnostic devices as BPM’s, ACCT’s, SEM grids, a slit-grid emittance device and a bunch shape monitor. Moreover, a magnetic spectrometer is supposed to measure the energy spread of the proton beam. Point-to-point imaging is foreseen to enable high energy resolution independently on the transverse emittance. Due to the limited space in the accelerator tunnel a special design must be chosen with the inclusion of quadrupole magnets. The present contribution gives an overall presentation of the test bench and its devices with a special emphasis on the magnetic spectrometer design.
