The fundamental understanding of material response to a neutron and/or high heat flux environment can yield development of improved materials and operations with existing materials. A concept has been advanced to develop a facility for testing various materials under extreme heat and neutron exposure conditions at Princeton. The Extreme Environment Materials Research Facility comprises an environmentally controlled chamber (48 m3) capable of high vacuum conditions, with extreme flux beams and probe beams accessing a central, large volume target. The facility will have the capability to expose large surface areas (1 m2) to 14 MeV neutrons at a fluence in excess of 1013 n/s. Depending on the operating mode. Additionally (deuterium) beam line power of 15-75 MW/m2 for durations of 1-15 seconds is planned. The facility will be housed in an existing test cell that previously held the Tokamak Fusion Test Reactor (TFTR).
