Based on a water-dielectric helix line, a 2.2 m long accelerator with a diameter of 0.4 m was designed and tested. The influence of the impedence mismatching between the joint section in pulse forming line and the helical line on the voltage waveform of the diode was analyzed. A high impedance annulus made of macromolecule material with an inner radius of 10 cm and an outer radius of 18 cm was added to the joint section. By making the impedance of the joint section be close to that of the helical line and the electric length minish, the upshot was eliminated, the fall time was minished, and a square pulse with a risetime about 18 ns, a fall time about 40 ns and a pulse top duration about 200 ns was obtained.
