Phys. Rev. Lett. 94, 125504 (2005) [4 pages]Shock Temperature Measurement Using Neutron Resonance Spectroscopy
See accompanying Physics Focus We report a direct measurement of temperature in a shocked metal using Doppler broadening of neutron resonances. The 21.1-eV resonance in 182W was used to measure the temperature in molybdenum shocked to ∼63 GPa. An explosively launched aluminum flyer produced a planar shock in a molybdenum target that contained a 1-mm thick layer doped with 1.7 at. %182W. A single neutron pulse, containing resonant neutrons of less than 1 μs duration, probed the shocked material. Fits to the neutron time-of-flight data were used to determine the temperature of the shocked molybdenum. © 2005 The American Physical Society URL:
