An ultra-high-speed front-end intelligent digital transmission system for high-intensity pulsed radiation field diagnosis

A Real-time Sampling System for Transient Pulsed Signals (RSTPS system) has been designed and implemented, which has been introduced in the 16th IEEE NPSS Real Time Conference, and this system is recently upgraded. Now the bandwidth is up to 448MHz with a dynamic range over 40dB. Some new functions are developed in order to make sure that the transient pulsed signal can be discriminated from the interference signals and recorded reliably in the high-intensity pulsed radiation field, which make the RSTPS system as an ultra-high-speed front-end intelligent transmission system. The most significant modification is that the sampling process of this system will be automatically pre-triggered only by the signals with designated characteristic. All the new functions are implemented in a FPGA and tested to be functional. Finally, the application of transmitting transient pulsed signals produced by the X-ray detecting in the Z-pinch experimentation is completed, to verify the proper operation of this system when being used in the high-intensity pulsed radiation field.
