Design of fast pulse generator for Kicker power supply in HIAF

Kicker power supply is one of the key components in the injection and extraction system of HIAF (High Intensity Heavy Ion Accelerator Facility, the 12th five-year national big science project). The PFN-Marx generator technology based on solid-state IGBT switch will be applied to HIAF-Kicker power supply. Hundreds of fast pulse signals are required to control these IGBTs. The PFN-Marx generator has many requirements for these control signals, such as adjustable pulse-widths and time-delay. The maximum value of adjustment accuracy of the pulse-widths and delay among multiple control signals need to be 10ns. In this paper, a fast pulse generator circuit based on an emerging ARM-embedded FPGA have been designed for HIAF-Kicker power supply. The test results show that the output performance of the fast pulse generator circuit meets the requirements of the PFN-Marx generator.
