A Device to Determine the Temperature of Plasma

摘要

This invention pertains to a device for measuring the temperature of plasma by the method of applying spectral lines. When this method is used to determine the temperature of plasma in the role of this device using an incandescent light creates a continuous spectrum source on the background of which is observed the individual spectral line of the investigated object. The employment of such a light, when investigating the temperature of plasma, is impossible because the brightness temperature of the source of the continuous spectrum should be no less than the brightness temperature of the investigated object (in an incandescent light this temperature does not exceed 3000). To increase the upper limit of the measured temperature, when investigating plasma, it is proposed according to the investion to use in role of continuous spectrum source a pulsed lamp with brightness smoothly changing with time. Such a lamp gives a continuous spectrum with spectral distribution close to the solar spectrum and its brightness temperature can reach 15000.
