Abstract
The use of microstrip Blumlein pulse generators to produce nanosecond high voltage pulses is discussed: such generators can give higher output voltages than simple single-cable generators. Two versions of an inexpensive and easily-constructed circuit are described: the first uses and avalanche transistor as switch, producing fixed amplitude ( approximately 100 V) pulses of either polarity at kHz repetition rates: the second circuit uses a mercury-wetted reed relay as switch and gives 5 ns output pulses variable in amplitude from 0 and 4 kV, with stable amplitude, nanosecond rise and fall time, and very high reliability, with repetition rates up to 250 Hz.
