“…LTD cavity with different parameters has been successfully developed around the world [27][28][29][30][31][32][33][34][35][36][37][38][39]. In some applications with ∼100 kA current, for example, x-ray radiography, LTD cavities have been integrated into facilities [27,29,[35][36][37][38].…”

We present a fusion-oriented pulsed power module M-50, which is based on the linear transformer driver (LTD) and magnetically insulated inductive voltage adder (MIVA) technologies. The module M-50, which consists of 50 identical LTD cavities connected in series, is one of the 60 modules of a fusion-scale pulsed power facility. M-50 is a comprehensive test bed for LTD integration and engineering validation. Each cavity consists of 32 bricks and has an output capability of 90 kV=1.0 MA=120 ns to the matched load. The output power of the 50 cavities is added with a MIVA, whose operation impedance is approximately matched to both source and load. Therefore, it has a nominal output capability of 4.5 MV=1.0 MA=120 ns to 4.5 Ω resistive load. The module is divided into five groups, and each group has ten cavities in series. The inner stalk of the MIVA is divided into five main straight segments. Conical transitions are employed to connect adjacent straight segments. The output end of M-50 is shrunk and connected a ring-cathode diode, whose cathode and anode radii are identical to those of a 12-m-long transmission line in the fusion facility. In this paper, the general concept of the fusion accelerator, the physical design, engineering design and development progress of M-50 are described for the first time.

“…For such an IVA, part of the MITL is located within, and is concentric to, the IVA's cavities. Following this precedent, Kovalchuk et al [1,5,12], Mazarakis et al [6,8,11,25,29,31,32,36], Kim et al [15,18,33], Rose et al [17,27], Leckbee et al [22,24,28], Olson [26], and Gomez et al [35] developed designs of LTD modules that drive an internal MITL. Such modules have been considered for zpinch-physics [1,5,8,11,25,29,[31][32][33]35,36], x-rayradiography [6,11,15,17,18,22,24,27,28], excimer-laser [12], and inertial-confinement-fusion (ICF) [25,26,29,31] applications.…”

We demonstrate that a wide variety of current-pulse shapes can be generated using a linear-transformerdriver (LTD) module that drives an internal water-insulated transmission line. The shapes are produced by varying the timing and initial charge voltage of each of the module's cavities. The LTD-driven accelerator architecture outlined in [Phys. Rev. ST Accel. Beams 10, 030401 (2007)] provides additional pulseshaping flexibility by allowing the modules that drive the accelerator to be triggered at different times. The module output pulses would be combined and symmetrized by water-insulated radial-transmission-line impedance transformers [Phys. Rev. ST Accel.
