NBI

NBI Power supply & Data Acquisition Division

Introduction:

A Neutral Beam Injector (NBI) System provides additional heating to the SST-1 Tokamak, it is designed for injecting 1.7MW power into the plasma. As a first step in the development, the NBI system with a prototype ion source has been commissioned and operated. The 1st stage experiment focused on tests of the integrated control and electrical sub-systems. A filament based Prototype hydrogen positive Ion Source was used on the NB test stand at Institute For Plasma Research (IPR), India. The test stand also comprises of essential components such as the Vacuum system, Gas feed system, some diagnostics and the data acquisition system. The Control system for NBI has been developed using a combination of Programmable Logic Controller (PLC) and a VME Based system.

Objective:

To provide controlled and uninterrupted operation of Neutral beam injection system with safety and

Acquire experiment data for online as well as for post analysis of experiment

Current status:

NBI sub-systems have been integrated and tested with indigenously developed prototype ION source.

PINI has been installed and operation initiate. NBI system has been operated up to 40KV of acceleration voltage and ~17A current.
