The Neutrinos at the Main Injector (NuMI) project will extract 120-GeV protons from the FNAL Main Injector in 8.56-{mu}sec spills of 4 x 1013 protons every 1.9 sec. We have designed secondary emission monitor (SEM) detectors to measure beam profile and halo along the proton beam transport line. The SEMs are Ti foils 5 {mu}m in thickness segmented in either 1-mm or 0.5-mm pitch strips, resulting in beam loss {approx}5 x 10-6. We discuss aspects of the mechanical design, calculations of expected beam heating, and results of a beam test at the 8-GeV transport line to MiniBoone at FNAL.
