Design and Integration of SMBI System for SST-1 Tokamak

Supersonic molecular beam injection (SMBI) is one of the most effective fuelling methods for injecting neutral particles at very high velocity into the plasma core. Due to higher speed and lower divergence, the beam penetrates several centimetres into the plasma and hence increases the fuelling efficiency. For SST-1 Tokamak, two types of SMBI systems are proposed. One will be installed in the low field side (LFS) while other will be integrated in the high field side (HFS). This paper describes the design, fabrication and implementation of SMBI system in SST-1 Tokamak.
