Аннотация:Summary form only given, as follows. Well known are nanosecond HV periodically pulsed generators based on high-coupling Tesla transformers and long coaxial forming lines with oil insulation. Combining Tesla transformer with long forming line allowed substantial increase in its charging efficiency and resulted in production of relatively compact HV generators and high-current electron accelerators with the average power in the range of several hundreds kilowatts. These accelerators are widely applied for HPM pulse production at high pulse repetition rates. Increasing the pulse width of the HV generators requires using longer forming lines. In the case of relatively high-ohmic loads, the problem may be used, alternatively, by utilizing spiral forming lines. This allows an increase in the generator impedance and pulse width, keeping the same stored energy, and with no substantial increase in the generator size. This paper presents a nanosecond periodically-pulsed generator based on a spiral line charged by means of a high-coupling Tesla transformer. At repetition rate of 100 p.p.s., 100-ns, 600-kV pulses were produced in a /spl sim/100-Ohm load.
