A high voltage and nanosecond Blumlein pulse generator has been developed to produce an output pulse whose voltage level is greater than 250 kV and pulse duration 5 ns. The generator consists of various components such as a charging circuit, a pulse transformer, and a spark gap switch. As a heart of the generator, a Blumlein pulse forming line has been constructed in the cylindrical form using ...

Blumlein pulsers are well suited devices for high voltage pulse generation in the range of nanoseconds or microseconds. They consist of pieces of transmission lines charged in parallel and discharged synchronously in series into the load by using a single switch. The main problems with this type of circuit are the presence of the shield cable impedance that contributes to the power loss of the ...

A Blumlein line is a particular Pulse Forming Line, PFL, configuration that allows the generation of high-voltage sub-microsecond square pulses, with the same voltage amplitude as the dc charging voltage, into a matching load. By stacking n Blumlein lines one can multiply in theory by n the input dc voltage charging amplitude. In order to understand the operating behavior of this electromagneti...

To produce an acceptable electron beam, the Dual-Axis Radiographic Hydrodynamic Test (DARHT) Facility accelerators require high-voltage pulses that are flat to within ±1% for 65±5 ns. Achieving this accuracy and pulse duration in operation on the Integrated Test stand (a fullscale prototype of the DARHT 4-Mev injector and first eight linear induction accelerator cells) has required fine-tuning ...

We have developed a series of techniques which are useful for operating two Blumlein generators from one Pulse power source, or a single Blumlein with two separate lines and switches. These techniques and operating experience with these devices are outlined in this puper as applied to the Gemini dual Blumlein, and the Tempo device with two switches.

In the reported article, we have simulated the pulsed high voltage direct current (DC) source and Blumlein transmission line by Multisimulation13 (National Instruments, Inc). In the generation of high voltage pulses at the optimum repetition rate, we have observed and investigated the waveform behavior of voltage in the Blumlein transmission line.We present the simulation results of pulsed high...

Technology demonstrations of key components at LANL for the Dual-Axis Radiographic Hydro Test (DARHT) Facility including the turnkey Induction Cell Pulsed Power Supply (ICPPS) delivered by Maxwell have been in progress at the DARHT Integrated Test Stand (ITS) for over three years. The prototype system has accumulated >35,000 shots to date with no component failures and only minor system malfunc...
