Synchronization of high speed framing camera and intense electron-beam accelerator

Area of Science:

• Physics
• Engineering

Background:

• High-speed framing cameras (HSFC) and intense electron-beam accelerators (IEBA) require precise synchronization for effective operation.
• Existing synchronization methods may lack the necessary precision or speed for certain applications.

Purpose of the Study:

• To develop and validate a novel trigger program for synchronizing HSFC and IEBA.
• To achieve a precise trigger signal with specific rise time and amplitude characteristics.

Main Methods:

• A trigger program was designed incorporating light signal acquisition from the IEBA main switch and a signal processing circuit.
• An avalanche photodiode (APD) module collected light signals, followed by signal processing to generate the trigger signal.
• The trigger program was integrated with an IEBA, and timing parameters were measured.

Main Results:

• The trigger program generated a signal with a 17 ns rise time and 5 V amplitude.
• A stable synchronization was achieved between the HSFC and IEBA with a 30 ns delay.
• A 150 ns delay was observed between the trigger signal and flashover current during surface flashover experiments.

Conclusions:

• The developed trigger program successfully synchronizes HSFC and IEBA.
• The system effectively compensates for trigger signal processing time and HSFC inherent delay.
• The achieved synchronization meets the requirements for high-speed dynamic event capture.
