One of the future multi-MW accelerators is the LBNE Experiment where Fermilab plans to produce a beam of neutrinos with a 2.3 MW proton beam as part of a suite of experiments associated with ProjectX. Specifically, the LBNE Neutrino Beam Facility aims for a 2⁺ MW, 60-120 GeV pulsed,high intensity proton beam produced in the ProjectX accelerator intercepted by a low Z solid target to facilitate the production of low energy neutrinos. The multi-MW level LBNE proton beam will be characterized by intensities of the order of 1.6·10⁺¹⁴ p/pulse, σ_radius of 1.5-3.5 mm and a 9.8 μs pulse length. These parameters are expected to push many target materials to their limit thus making the target design very challenging. Recent experience from operating high intensity beams on targets have indicated that several critical design issues exist namely thermal shock,heat removal, radiation damage,radiation accelerated corrosion effects,and residual radiation within the target envelope. A series of experimental studies on radiation damage and thermal shock response conducted at BNL and focusing on low-Z materials have unraveled potential issues regarding the damageability from energetic particle beams which may differ significantly from thermal reactor experience. Irradiation damage results for low-Z materials associated with the LBNE and other high power experiments will be presented.
