Development of an Extreme Environment Materials Research Facility at Princeton

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).
