The Long Baseline Neutrino Experiment (LBNE) Neutrino Beam Facility at Fermilab will use a high energy proton beam on a solid target to produce a neutrino beam aimed at underground detectors at the DUSEL site in South Dakota. Initial proton beam power is planned to be 700 kW with upgrade capability to greater than 2 MW. Solid target survivability at such incident beam power is of great interest and an R&D program has been started to study the relevant issues. Areas of study include irradiation testing of candidate target materials at the BLIP facility at BNL, multi-physics simulations of solid target/beam interactions at RAL, autopsies of used NuMI targets, high strain rate effects in beryllium, and alternative methods of target cooling. Status and results of these studies are presented as well as a summary of planned future high power target R&D efforts.
