Abstract

The temperature recorded immediately after hypervelocity collision of microparticles comprising iron and nickel with a silver-coated piezoelectric plate was analyzed using photomultipliers of different spectral response characteristics. The conversion rate between the velocity and temperature is estimated to be ~900 K/km/s in the velocity range of 10-40 km/s. This rate is greater than that reported earlier.
