University-scale pulsed-power system using linear transformer driver

Linear transformer driver (LTD) {[}A. A. Kim \textit{et al.}, Phys. Rev. ST Accel. Beams \textbf{12}, 050402 (2009){]} is a compact pulsed-power system suitable for x-ray sources or laboratory astrophysics and space research for university-scale laboratory. A LTD with $20$ bricks storing $8\;{\rm kJ}$ of total energy delivering $500\;{\rm kA}$ to the load with a $100\;{\rm ns}$ rise time is being built. It will be used for following two purposes: (1) gas-puff z pinches generating soft x-ray sources for bio-medical research in the future and (2) generating plasma jets to study interactions between plasma flows and unmagnetized/magnetized obstacles analogous to the interactions between solar winds and planetary magnetic fields or unmagnetized planets. One brick consisting of two $40\;{\rm nF}$ capacitors connected in series charged to $\pm100\;{\rm kV}$ and delivering a peak current of $25\;{\rm kA}$ to the load was built. The results of current measurement and circuit characteristics are shown.
