Effects of tracer in fuel on X-ray diagnostics of implosion

Diagnosing conditions of compressed fuel is a critical aspect of ICF capsule implosion experiments. A common diagnostic technique is to add a small concentration of high- or mid-Z dopant to the fuel, and measure the emission from the dopant either spectroscopically or by imaging. With radiative hydrodynamic simulations and post-processing of X-ray imaging for implosions, the designs of the fuel capsule are optimized, and the effects of tracer in fuel on X-ray diagnostics of implosion are analyzed. The results show that for the capsule of D2 fuel doped with argon at about 1% atomic fraction, although the implosion yield reduces by about 15%, the X-ray intensity of fuel increases by 50 times and the size of X-ray imaging is enlarged by about 30%, which is beneficial to the diagnosis of the
