Abstract

A mirror-rotating type compact streak camera whose maximum streak rate was faster than 10 mm/microsecond(s) and a strong Xenon-flash lamp with a wide flash area were produced for impact- shock study of solids. The streak camera mainly consists of the high-frequency motor with an air bearing of 120,000 rpm in a maximum rotating rate, the square-shaped mirror, the lens system with a 15 micrometers -width slit, and the circular-shaped film mount case of 830 mm in inner diameter. The flash lamp consists of two parallel Xenon tubes of 40 mm in length and 10 mm in diameter, which were stimulated with two high voltage condensers of 100 (mu) F and 2 kV. The shock-wave measurement experiments of solids in several 10 s of GPa region were performed by the inclined-mirror method using the streak camera and flash lamp in combination with the keyed-powder gun.
