Performance Characteristics of an EFI via VISAR

Objectives of an exploding foil initiator (EFI)

  • - Flyer acceleration for shock-initiating an explosive
  • - Miniaturization of a Pyro-Mechanical device for air bags and space missions.

Velocity interferometer system for any reflector (VISAR)

  • - Measuring a target surface velocity
  • - Velocity measurement plays a vital role in the dynamic compression research

Laser-Induced Breakdown Spectroscopy (Fire Investigation)

Role of LIBS of fire debris residues

  • - Determining an ignition source (fuel constituent, type of ignition source)
  • - Analysis of accelerants in fire debris → Detecting the use of a fire accelerant at a crime scene can be
    the difference between classifying a fire as accident or an act of arson

Investigation of the ignition source and existence of fire accelerant by using the LIBS

  • - Depth profiling can confirm the existence of combustion accelerant, suggesting that arson is the cause of fire
