Abstract:In spectroscopy, hollow cathode lamps are subject to increased requirements on radiation parameters. In order to perform verification of such lamps a highly stable source of spectral lines is needed, the intensity of which on the spectral lines will remain unchanged (≤1%) for a long time. A solution to this problem is proposed and a scheme of an experimental bench for a hollow cathode lamp with a negative feedback loop is presented. The developed device is used in control circuit, which is a highly stable sour… Show more
