Measurement of argon in laser fusion targets

The technique of argon determination in glass microspheres used in experiences on laser fusion is stated. The technique is based on registration of a spectrum of characteristic radiation of argon atoms, excited by β-radiation of tritium, contained in a target, or X-ray radiation of an external source for targets without tritium. The calculated dependencies of power of characteristic radiation on geometrical parameters of microspheres and results of measurement of various targets are submitted.
