  At the electron accelerator ELSA, a new external beamline is under construction, whose task is to provide a primary electron beam for detector tests. In the future, the accelerator facility will not only be offering an electron beam to the currently installed double polarization experiments for baryon spectroscopy, but to the new "Research and Technology Center Detector Physics" as well. This institution will be established near the accelerator in Bonn and is charged with the development of detectors for particle and astroparticle physics. The requirement for the new beamline is to be able to vary the beam parameters such as beam current and width over a wide range. With the resonance extraction method, it is possible to extract electrons with a maximum energy of 3.2 GeV slowly to the test area. A quasi-continuous external beam current of 1 fA to 100 pA can be offered. A further reduction of the beam current can be realized by utilizing the single-pulse operation mode at ELSA. The beam width can be changed in both transverse directions from 1 mm to 8 mm.
