Abstract

Abstract

The pulse power device will produce a strong electromagnetic environment in the process of discharge, which interferes with diagnostic systems in the experiment, leading to their failure to work properly. By selecting, transforming and delaying the time correlated signals, a trigger network has been established for diagnostic instruments in high energy density experiments on an 8 MA pulsed power device. The jitter of time interval between the trigger signal and the X-ray pulse is less than 2 ns, which meets the requirement to synchronize diagnostics with time resolution of nanosecond. Shielding and grounding techniques are used and effectively eliminate the jamming of strong electromagnetic environment and other stray signals produced by the discharge of the device, which also ensure the normal operation of diagnostic instruments and the quality of the experimental data.
- strong electromagnetic environment,
- diagnosis and measurement,
