  A number of particle physics experiments are being proposed as part of the
Department of Energy HEP Intensity Frontier. Many of these experiments will
utilize megawatt level proton beams onto targets to form secondary beams of
muons, kaons and neutrinos. These experiments require transverse size
measurements of the incident proton beam onto target for each beam spill.
Because of the high power levels, most beam intercepting profiling techniques
will not work at full beam intensity. The possibility of utilizing optical
transition radiation (OTR) for high intensity proton beam profiling is
discussed. In addition, previous measurements of OTR beam profiles from the
NuMI beamline are presented.
