The facility is used for applied research in dynamic materials, radiation sources, and fusion sources. This talk will provide an overview of the research done on the Z Machine, as well as additional pulsed power technology maturation efforts being done at Sandia as we consider possible architectures for a larger-scale driver. Plenary Session 1 Plenary Speaker: XIE Weiping - Chair: WANG Xinxin (BALL ROOMS 1 & 2#）[09:20-10:10] 09:20 [A2084] Design of a high reliability 4 MV flash X‐ray facility XIE Weiping (Institute of Fluid Physics, CAEP, China) Abstract: For the use of high valuable fluid dynamics experiment, a 4 MV flash X-ray facility (Sirius，天狼星) has been designed and is in fabrication at Institute of Fluid Physics (IFP). The Sirius has the ability to deliver 4 MV, 100 kA，60 ns electric pulse to a 40 Ω matched diode. It adopts a novel high reliability technical scheme with less active components of high power gas switch, which is based on Tesla Transformer, Induction Voltage Adder (IVA) and rod-pinch diode (RPD). The Sirius consists six-module induction voltage adder (IVA). Each module is identical and composed of a Tesla pulse transformer, intermediate storage capacitor, laser trigger gas switch, pulse forming line, self-breaking oil switch, water transmission line, and one induction cavity. The primary stored energy in Tesla pulse transformer is discharged in 4.0 µs into the intermediate storage capacitor. The operating voltage at the intermediate capacitor is about 1.2 MV when the two capacitors of the Tesla pulse transformer are charged to ±60 kV. The intermediate capacitor is switched out by Page 1 EAPPC & BEAMS 2018 / Programme Monday 17 September 2018 the laser triggered gas switch to 4.0 Ω, 30 ns pulse forming line which is discharged by the self-breaking oil switch to 7.0 Ω water transmission line. The forwarding going voltage wave at each water transmission line section is about 800 kV, 65 ns and added by six induction cavities. The 4.0 MV, 65 ns voltage pulse with positive polarity could be obtained to drive a 40 Ω RPD. The reliability and stability are the key issue of this facility. As the Tesla pulse transformer has only one gas switch the reliability is very high, it is employed to provide the primary energy instead of Marx generator. Another key factor of high reliability is low pre-fire probability and jitter of the laser triggered gas switch. Every laser triggered gas switch is triggered by one 266 nm laser and each switch can be triggered independently. Conservative electrical stress design is the third key factor of the high reliability. So, the Sirius contains 12 triggered gas switch and 6 oil self-breakdown gaps, which is expected to have the reliability up to 98%, 1.5 mm source diameter, and 10 rad dose at a distance of 1 m. The Sirius is 5 m wide, 5 m high and 17 m long.
