Development of Compact Plasma Radiation Source (CPRS) at IAC for imaging
The needs in Compact Pulsed Power X-Pinch Generators
- N.Ratakhin et al. "Compact pulse power generator for X-pinch researches" 28th ICPIG, July 15-20, 2007, Prague, Czech Republi [1]
"The main requirements imposed on the generator are the current amplitude 150-300 kA and the rate of the current rise 1-2 kA/ns. At the moment, these parameters of the current pulse can be provided only by enough large fixed-site generators weighing from 300 kg to several tons. These shortcomings limit to a great extent the feasibility of this diagnostic technique in studies of extreme states. Therefore, the design of a portable pulse generator which provides the required parameters makes it possible to proceed to a new level of diagnostics of fast processes."
Design's Possibilities
PRS based on transformation of ISIS Induction Cell Driver
File:ISIS Modification for X-pinch 012813.pdf
PRS based on building separate Marx Generator or (Marx Generator + Pulse Forming Line)
PRS based on Linear Transformer Driver (LTD) technologies
This design needs the massive ferromagnetive core and uses wireless induction technology to drive the current. This approach is good for design of large compact facilities, like Induction Accelerator or Z-Machine. We can uses the idea of LRC circuit without inductive voltage adder
