Abstract
Abstract A high-frequency, high-power generator of the type in which energy is stored in the capacitance of a transmission line and then discharged into a load by the action of a spark discharge device. The load is connected between one end of a transmission line conductor and ground and the other end of the same conductor is grounded. The line is folded and both ends of the other transmission line conductor are connected to the spark discharge device. A charging circuit applies a voltage to the latter conductor and when it reaches the discharge potential of the spark discharge device, the latter discharges to connect both ends of that conductor to ground. This provides relatively well-defined positive and negative pulses to the load.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
129 words
A pulse generator comprising: A. a transmission line having first and second conductors, each of which has first and second ends, B. a spark discharge device having first and second terminals, the first terminal of said discharge device being connected to said first end of said second transmission line conductor and said second terminal of said discharge device being connected to said first and second ends of said first transmission line conductor, C. a voltage source connected to apply a charging voltage to said first and second conductors to charge the capacitance between said conductors, whereby said capacitance repetitively charges to the ignition point of said discharge device and said discharge device then discharges to provide an output pulse at said second end of said second transmission line conductor.
Claim 2
Dependent Claim
129 words
A pulse generator comprising: A. a transmission line having first and second conductors, each of which has first and second ends, B. a spark discharge device having first and second terminals, the first terminal of said discharge device being connected to said first end of said second transmission line conductor and said second terminal of said discharge device being connected to said first and second ends of said first transmission line conductor, C. a voltage source connected to apply a charging voltage to said first and second conductors to charge the capacitance between said conductors, whereby said capacitance repetitively charges to the ignition point of said discharge device and said discharge device then discharges to provide an output pulse at said second end of said second transmission line conductor.
Claim 3
Dependent Claim
40 words
The pulse generator defined in claim 1 in which said transmission line is looped so that said first and second ends of said first conductor are in close proximity to each other relative to the length of said transmission line.
Claim 4
Dependent Claim
17 words
The pulse generator defined in claim 2 in which said transmission line is a coaxial transmission line.
Claim 5
Dependent Claim
24 words
The pulse generator defined in claim 1 including an electrical load connected between said first and second ends of said second transmission line conductor.
