Measurement of implosion trajectory for hohlraum-radiative-driven
View through CrossRef
The measurement of implosion velocity is the core problem of inertial confinement fusion and it is also a key quantity of estimation of fusion ignition. A clear implosion trajectory X-ray image of hohlraum-radiative-driven CH-capsule is obtained in Sheng-GuangII laser facility with 1600 J laser energy, triple frequency and 1 ns pulse width. KB-microscope coupled with X-ray streak camera whose temporal resolution is about 10 ps is used for diagnosis. The maximal velocity of implosion is about 160 km/s which can be extracted from the experimental trajectory data. The experimental data are compared with Multi1D simulation results of velocity and both are in good agreement with each other.
