Embodiment Construction

[0031] The core technical idea of ​​the present invention is: each level of all series modules is composed of a trigger branch and a main discharge branch, and the modules of the same level use a pulse to close the switch of the trigger branch, and transmit it to the main discharge branch of the same level through the angular transmission line The switch makes the same-level modules trigger and close synchronously; the electrodes in the multi-level series modules are compressed and sealed to form a secondary outer cylinder, which constitutes the LTD movement, and is loaded into a non-magnetic metal shell (such as aluminum or stainless steel, etc.), except for the first The grounding metal cover plate of the first-level and last-level modules is integrated, and the electrode plates between the modules are combined into one and have a hollow spoke shape, which is connected to the grounding electrode plate at the end of the cavity through the metal electrode; the positive and negat...

Abstract

The invention relates to a multi-stage series-connected linear transformer driver (LTD) and a trigger method of the LTD. The LTD comprises multiple series-connected stacked LTD modules, wherein all the LTD modules are disposed in a common non-magnetic metal housing. The technical problems of complicated trigger circuits, high manufacturing cost and difficulty in guaranteeing a trigger sequence by use of a conventional multistage series-connected LTD are solved. The multi-stage LTD modules are connected in series and stacked in a common housing, 3 to 4-stage LTD modules can share one trigger pulse, and all the LTD modules can share one charging cable, such that the number of introduced trigger cables and the number of charging cables are substantially reduced, conventionally quite complicated line arrangement is simplified, and the equipment operation reliability is improved.

Description

technical field [0001] The invention relates to a multi-stage series linear transformer drive source (Linear Transformer Driver, LTD for short), and a trigger method of the drive source. Background technique [0002] The LTD pulse source is connected in parallel through multiple low-inductance branches uniformly arranged in the radial direction, and uses electromagnetic coupling to realize the current superposition of multiple branches in a single stage and the voltage superposition of multi-stage series modules, and can directly obtain high-power pulses of 50-200ns at the leading edge. It has important applications in Z-pinch inertial confinement fusion (ICF) / fusion energy (IFE), flash photography, isentropic compression (ICE), intense laser, X-pinch and other fields. To realize Z-pinch ICF / IFE, dozens to hundreds of LTDs with an output voltage of several megavolts are required to be connected in parallel, and each LTD requires dozens of current MA-level LTD modules to be c...
