Abstract:
A set of transient real time two-line spectroscopy temperature measured system with quartz optical fiber was established. Two spectral lines are Cu I 510.5 and Cu I 521.8 nm respectively. Its maximum time resolution is up to 0.1 microsecond. The discharge spark temperature and spark discharge time of the nonel tube igniter under different voltage are 2,100-4,200 and 100-200 microseconds respectively. The spark discharge time increase with the rising of charge voltage. The discharge spark temperature variations versus the discharge time under different voltages, and the spark duration under different discharge conditions were studied with this instrument.
