Sample Test Array And Recovery (Star) Platform At The National Ignition Facility
REVIEW OF SCIENTIFIC INSTRUMENTS(2021)
摘要
We have developed the Sample Test Array and Recovery (STAR) platform for the National Ignition Facility (NIF) for studying the thermal and hydrodynamic responses of materials in extreme environments. The STAR platform expands the range of obtainable fluences and quadruples the rate that materials experiments can be conducted at the NIF. Example configurations are demonstrated for fluences spanning 0.56-34 J/cm(2) with environmental isolation for post-shot material recovery and inspection and up to 1740 J/cm(2) without isolation, with surface heating rates of up to 2 x 10(14) K/s. An example experiment involving thermally driven shock and spallation of aluminum alloy 7075 is briefly discussed. Published under license by AIP Publishing.
