Divertor configurations are commonly used in magnetic confinement devices such as a tokamak to 'Divert' the plasma so that the plasma surface interaction can occur locally to prevent the core plasma from getting diluted. Since they face the direct line of plasma 'Scrape off layer' which is the plasma edge, they are subjected to very high heat loads. A typical Divertor also consists of components constituting of refractory materials such as Tungsten. These components - also called as "Plasma Facing Components" - are primarily designed for extraction of heat flux and particle flux incident on them from the dense & hot plasma confined in the device. The plasma facing components are mounted on a support structure that constitutes the casette body. The Design of a divertor and the casette body also involves fabrication of such components to sustain various loads such as Thermal, Electomagnetic and Neutronic loads.
"High Temperature Technologies Division" (HTTD) is a division of Institute for Plasma Research (IPR) performing research and development in the following areas:
(1) Engineering Design & Analysis of Divertors components (also called as - "Plasma Facing Components") of plasma confinement devices, such as Tokamaks, relevant to thermo-nuclear fusion reactor technologies;
(2) Development of material joining technologies relevant to fabrication of Divertors Components;
(3) Development and/or Implementation of Destructive and Non-Destuctive Techniques relevant to inspection of DIvertor materials and components;
The division is also engaged in establishing some of the computational and experimental facilities needed for research & development, such as:
(1) Establishment of computational facilities required for engineering analysis/ simulation of Divertor Components.This includes:(a) Thermal Analysis; (b) Structural Analysis; (c) Electromagnetic Analysis; (d) Fluid Dynamics;
(2) Establishment of experimental facilities and utilities required for testing of materials/ test mock-ups/ components /assemblies relevant to Divertors Components.
