Synchronization of parallel intense electron beam accelerators based on single trigger generator.

Area of Science:

• High-energy physics
• Pulsed power systems
• Accelerator technology

Background:

• Intense electron beam accelerators (IEBA) are crucial for various applications.
• Precise synchronization of multiple IEBAs is challenging but essential for advanced experiments.
• Existing methods often suffer from significant timing jitter.

Purpose of the Study:

• To develop and validate a method for precisely synchronized triggering of multiple IEBAs.
• To investigate the effectiveness of a single trigger generator for synchronous IEBA operation.
• To reduce synchronization-related jitter in high-power pulse generation.

Main Methods:

• Designed a trigger generator using a fractional-turn ratio saturable-pulse transformer and a six-stage Marx generator.
• Utilized a corona-stabilized triggered switch (CSTS) for the main IEBA switch.
• Experimentally tested synchronous triggering of two IEBAs using both independent and single trigger generators.

Main Results:

• A single IEBA achieved over 500 kV output with <4 ns jitter.
• Synchronous triggering of two IEBAs with independent generators resulted in 6.1 ns jitter.
• Using a single trigger generator reduced synchronization jitter by 31% to 4.2 ns.

Conclusions:

• The proposed CSTS and trigger generator design enables precisely synchronous triggering of multiple IEBAs using a single generator.
• This approach offers a promising and effective method for generating high-power pulses with improved accuracy.
• The findings pave the way for more sophisticated applications requiring synchronized high-energy electron beams.
