The SST-1 (steady state superconducting tokamak) is a mid size tokamak with major radius 1.1 meters and minor radius 0.2 meters. For the initial phase of operation of SST-1 optical imaging diagnostics is installed which give information on plasma size, shape, movement, etc. This diagnostics consists of three CCD cameras. Two cameras have wide angle view which is placed diametrically opposite to cover almost 90% of the vacuum vessel (Figure 27.1). Each camera has a viewing angle of around 70°. The third camera is so position to get the tangential view of the plasma. It gives information about emission distribution in poloidal cross-section (Figure 27.2). Figures 27.1 and 27.2 shows the arrangement of the radial and tangential view respectively on the machine.

India aims to create a flexible pellet fueling system that would require minimum change in the progression from the Steady State Superconducting Tokamak 1 (SST-1) to a higher-scale tokamak for fusion demonstration. The SST-1 is a plasma confinement experimental device in the Institute for Plasma Research (IPR), India. Srinivasan et al.3 have discussed the contribution of fusion reactors to fulfill the energy demand in India.
