Apparatus and configuration of the laboratory-based projector system at the Institute of Space and Astronautical Science (ISAS), Sagamihara, in March 2015; a upper part of the projectile chamber, b explosive chamber, c interior of the projectile chamber, d, e gas sample cylinders, and f schematic diagram of the entire simulation. The anomalous element profiles of metal (e.g., Aluminum) derived from the explosive chamber are potential indicators to trace the artifact if the sample has affected by off-nominal projectile operation
