【Abstract】 The design and experimental results are described on a helical Blumlein line in this paper. The experimental results show that by introducing a helical Blumlein line with about 0.5 m long as pulse forming line(PFL), a square pulse with rise time about 120 ns and pulse duration 270 ns could be obtained. However using the same long Blumlein line as PFL, only a square pulse with 31ns pulse duration could be obtained. The helical Blumlein line can be used in long pulse research and design of higher impedance pulsed power supply.更多还原
