Description: 

B.Tech CSE  students had visited IPR on 10/01/2015 along with faculties.  Students had visited various department and gathered the project information. 

ADITYA TOKAMAK

ADITYA is the first indigenously designed and built tokamak of the country. It was commissioned in 1989. ADITYA, a medium size Tokamak, is being operated for over a decade. It has a major radius of 0.75m and minor radius of the plasma is 0.25 m. A maximum of 1.2 T toroidal magnetic field is generated with the help of 20 toroidal field coils spaced symmetrically in the toroidal direction. The major subsystems and parameters of the machine have been described elsewhere. 

STEADY STATE SUPERCONDUCTING TOKAMAK(SST) 

A steady state superconducting tokamak SST-1 is under design and fabrication at the Institute for Plasma Research. The objectives of SST-1 include studying the physics of the plasma processes in tokamak under steady state conditions and learning technologies related to the steady state operation of the tokamak.

The specific objective of the SST-1 project is to produce 1000 s elongated double null divertor plasma

BASIC PLASMA PHYSICS EXPERIMENTS

The major experiments are Large volume plasma device (LVPD), Free-Electron Laser (FEL) Experiment, Non-neutral toroidal plasma, Dusty plasma experiments, plasma nitriding studies, plasma immersed ion implantation, anode arc studies, radio frequency experiments etc. 

In the LVPD experiments, detailed studies are being carried out on excitation and propagation of whistler waves. In the FEL experiment, sheet relativistic electron beam is propagated through a fifty period electromagnet wiggler and radiation in microwave ferquency range is observed. Study of dicotron instability and electron cloud behavior in toroidal magnetic field is done in non-neutral plasma experiment. Excitation of dust acoustic waves, formation of coulomb crystal etc is studied in dusty palsma experiments. Physics of plasma -surface interaction and wave-particle interaction is studied in plasma nitriding and rf experiments respectively.
