Measurement Of Temperature After Hypervelocity Collision Of Microparticles In The Range From 10 To 40 Km/s

摘要

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.
