A typical device for carrying out sophisticated and complex dusty plasma experiments is designed, fabricated and made operational at the Institute for Plasma Research, India. The device is named as complex plasma experimental device (CPED). The main aim of this multipurpose machine is to study the formation and behaviour of dust vortices in the absence of external magnetic field under the effect of...
The conceptual Scheme of Focusing the High pulsed microwave power generated by “VIRCATOR” on plasma produced in “SYMPLE”, using Plasma Lens, is discussed.
Preliminary experimental results of an axially extracted virtual cathode oscillator (vircator) built on the low impedance pulsed electron beam accelerator AMBICA-600 is reported. The AMBICA-600 pulsed power system mainly comprises of a coaxial waterline charged from single turn Tesla transformer. Waterline has impedance of ~5Ω and generates pulse width of ~60ns. The generated pulsed high power microwave...
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.
The spatial and temporal structures of magnetic signal in the tokamak ADITYA is analysed using recently developed singular value decomposition (SVD) technique. The analysis technique is first tested with simulated data and then applied to the ADITYA Mirnov coil data to determine the structure of current peturbation as the discharge progresses. It is observed that during the current rise phase, current...
