An experimental system, SYstem for Microwave PLasma Experiments (SYMPLE), is being developed in order to investigate the physics of linear and nonlinear interaction of a high-power microwave (HPM) with an overdense plasma (plasma frequency $f_{p} \,\, >$ microwave frequency $f_{\mu })$ . The physics of interaction has implications in inertial fusion. The developmental task is taken up in two...
An experimental system being developed in our laboratory, named “SYMPLE” (System for Microwave and Plasma Experiments), aims at investigation of nonlinear interaction of high power microwave (HPM) with over-dense plasma. The Phase-1 stage of the system involves interaction using a 3.1 MW, 3 GHz, pulsed (5μs) output from an S band magnetron. The time sequence of the experiment necessitates the HPM...
In order to investigate physics of nonlinear interaction of high-power microwave (HPM) with an over-dense (fplasma > fwave) plasma, an experimental system SYMPLE (System for Microwave and Plasma Experiments), is being developed. The work is taken up in two phases: Phase-1 addressing interaction of plasma with moderate power HPM, ((1/2;εEμ2) /(nkTe) ∼ 1), and Phase-2 involving extremely intense...
A compact generator based on Tesla transformer for application in plasma opening switch has been developed. This system will be used to produce microwave for plasma-microwave interaction studies. Overall dimension of this system is 6 feet by 4 feet. This system is designed to operate with up to 350 kV on water pulsed forming line to generate 75 kA, 40 ns pulse, which further will be compressed in...
The conceptual Scheme of Focusing the High pulsed microwave power generated by “VIRCATOR” on plasma produced in “SYMPLE”, using Plasma Lens, is discussed.
A Pulse Forming Network (PFN) with mutual coupling has been designed, developed and tested for its performance as a pulsed (~100 μs) high voltage (up to 10 KV) source for washer gun plasma production in SYMPLE (SYstem for Microwave PLasma Experiments). Detailed account of the PFN parameters as well as the test results on plasma discharge production is presented here.
An experimental proposal to investigate the physics of interaction of extremely intense (eEem/mωc ~ 1) microwave in an overdense plasma is discussed. The output from a VIRCATOR (2-10 GHz, ~ 1-3 GW) based pulse (~30 ns) powered microwave source will be coupled to a large volume (φ 50 cm and length 150 cm) plasma of density ~ (1-10)×1018/m3. The proposed investigations include wave absorption in plasma,...
A system “SYMPLE” is being developed at our laboratory to investigate the interaction of high power microwave and plasma. A brief account on the development of a plasma source that satisfies the prerequisites required for SYMPLE is discussed.
