A slotted plate photodiode beam position monitor was built and installed on a user beam line. The detector is positioned in front of the first optical component of the beam line intercepting ∼ 3 mrad of synchrotron radiation. A 25-μm-thick Be foil strongly attenuates photons with hv < 800 eV and improves the position sensitivity by reducing the vertical angular divergence of the effective photon beam by more than a factor of 10. With a 125-μm gap at 45° angle between the diode plates, the detector has a linear working range of ∼ ±800 μm. The vertical position sensitivity of the beam position monitor is ∼ 5 μm.
