Abstract
DNA's future X-ray simulators are based upon inductive energy storage, a technology which offers the promise of more compact and affordable energy storage and delivery for larger systems. DECADE is a prime example of this technology. DECADE will store approximately 10 megajoules and deliver about 2 megajoules to separate bremsstrahlung sources or to a combined plasma radiation source load. Two DECADE prototype modules have already operated, demonstrating that key parameters can be met. The concept of inductive energy storage is illustrated. An opening switch is placed in parallel with the load. Energy is delivered to the load when the switch rapidly increases its resistance (i.e., opens). The most commonly used form is the plasma opening switch (POS) which opens as plasma charge carriers are depleted or move out of the conduction region under the influence of J/spl times/B forces. The scaling of the voltage produced across the switch is also illustrated. It is proportional to the current and inversely proportional to the opening time. Switch performance has been demonstrated with short opening times and lower switch voltages. The state of switch technology is also indicated. The risk of switch performance would be lower for soft X-ray simulators if plasma radiation source loads can operate with longer implosion times.
