Abstract
ADITYA Tokamak is a medium size ohmically heated tokamak. The hot plasma interacts with the vacuum vessel wall introducing impurities in the plasma and also damages the vacuum vessel wall. Limiter is used to reduce plasma - wall interaction and protect the vacuum vessel wall as well as inside components. It also controls impurity generation. ADITYA has a set of two types of limiters (i) Safety limiter (ii) a Poloidal limiter. Formally all the limiters are made of shaped graphite tiles fixed on stainless steel base plates. But graphite tiles are responsible for low Z impurities in plasma. To avoid these low Z impurities Molybdenum tiles are suggested. In this paper, we are going to present ansys analysis of surface temperature rise of molybdenum tiles compared to graphite tiles when used as Poloidal Limiter during plasma discharges in Aditya tokamak. The analysis is carried by ANSYS 11.0 software using Transient Thermal Analysis module. The results are compared with experimental results for graphite tiles. The graphite and molybdenum tiles are analyzed under same conditions.
