Abstract

The main causes of the energy losses in a tokamak are radiation, ion-neutral charge exchange and plasma transport processes. Infrared thermography is carried out on the poloidal limiter of the ADITYA tokamak with an infrared camera. Analysis of these thermographic images can enhance our understanding of plasma-limiter interaction. Surface temperature measurement can give us heat flux falling on limiter and its variation with time. This flux measurement over time can be useful in calculation of power balance and can be compared with total input power. The measured toroidal temperature is, in general, in agreement with that expected for ADITYA shaped limiter tiles. This paper describes the details of thermographic measurement done in the ADITYA tokamak.
