MEASUREMENT OF THE POLARIZATION OF LINE PROFILES IN THE X-RAY REGION AND THE DIAGNOSTIC POSSIBILITIES

摘要

A relatively new technique for polarization analysis of X-ray line profiles was employed. A significant difference in profiles of the Al XII Lyman γ line registered in two orthogonal linear polarizations was observed in a powerful Z-pinch. This is a measurement of a polarization of X-ray line profiles in laboratory plasmas. The observed polarization of the profiles was interpreted as being due to strong Langmuir waves developed primarily along the discharge current. This diagnostic technique could also be applied to other areas of high-temperature plasma research, for example, to laser fusion. It may be the first measurement of polarization using the profiles of X-ray lines.
