A secondary emission monitor (SEM) was developed for beam profile measurements at the Ultra-low energy Storage Ring (USR) that will be installed at the future Facility for Low-energy Antiproton and Ion Research (FLAIR) in Darmstadt, Germany. The detector consists of an Aluminium foil on negative potential, a grounded mesh placed in front of the foil, a chevron type microchannel plate (MCP), a phosphor screen and a camera connected to a PC. Simulations of the optimized design together with experimental results with keV protons are presented in this contribution. In addition, the usability of the detector for low energy antiproton beam profile measurements is discussed.
