| Abstract: | A terminal synchronizer in Inertial Confinement Fusion(ICF) is introduced in this paper. It has medium time resolution and is based on the VXI bus system standard. Via VXI bus, a computer can control pulse-width, amplitude and time delay of its output pulse. The electronic test has presented that its inherent time delay is less than 30 ns, the front edge time of its output pulse is less than 14 ns and the time jitter is less than 5 ns. The test results prove that the synchronizer can be used in ICF experiment. |
