In inertial confinement approaches to fusion, the asymmetry of target implosion is a major obstacle to achieving high gain in the laboratory. A recently proposed octahedral spherical hohlraum makes it possible to naturally create spherical target irradiation without supplementary symmetry control. Before any decision is made to pursue an ignition-scale laser system based on the octahedral hohlraum, one needs to test the concept with the existing facilities.

The experiment of inertial confinement fusion by the "ShengGuang (SG)-III" prototype laser facility is a transient and extreme reaction process within several nanoseconds, which could form a very complicated and intense electromagnetic field around the target chamber of the facility and may lead to harmful effect on people around. In particular, the biological effects arising from such specific environment field could hardly be ignored and have never been investigated yet, and thus, we reported on the investigation of the biological effects of radiation on HaCat cells and PC12 cells to preliminarily assess the biological safety of the target range of the "SG-III" prototype laser facility. The viability revealed that the damage of cells was dose-dependent.

Article Synopsis
  • A neutron time-of-flight (nTOF) system has been set up at China's largest laser facility to analyze neutron spectra during inertial confinement fusion experiments.
  • The system comprises 11 fast plastic scintillation detectors designed to gather data on neutron yield, ion temperature, and neutron bang time.
  • It successfully measures various neutron yields and provides accuracies around 10% for yield and temperature, while measuring neutron bang time within 60 picoseconds, making it a key diagnostic tool for over 200 experimental shots annually.
