A double shell z-pinch with an axial magnetic field
is considered as a K-shell plasma radiation source.
One-dimensional radiation-hydrodynamics calculations performed
suggest that this scheme holds promise for the production of
the K-shell radiation of krypton (hν ≈
12–17 keV). As a first step in verifying the advantages of
this scheme, experiments have been performed to optimize a neon
double-shell gas puff with an axial magnetic yield for the
K-shell yield and power. The experiments show that the
application of an axial magnetic field makes it possible to increase
the K-shell radiation power and reduce the shot-to-shot
spread in the K-shell yield. Comparisons between the
experiments and modeling are made and show good agreement.
