Description

Thailand Institute of Nuclear Technology (TINT) plan to operate the refurbished HT-6M tokamak near 2020. Although, the tokamak is old, small and low in power, it is still useful for the plasma and fusion education. With regards to researching, there are still rooms for frontier researches crucial for efficient fusion operations. One of them is the phenomena related to dust and droplet transport. In this work, we aim to track various dust during transport under the plasma profiles of the HT-6M. The plasma profiles are generated by the TASK code. The simulation of dust is conducted by the Dust and Droplet Tracking (DDT) code. Various dust parameters including selected notable dust materials e.g. carbon, boron, lithium etc. are implemented in the simulation to learn their behaviors for HT-6M. The aim for the work is to support on the preparation of the HT-6M installation. This is because the knowledge gained from experiments and diagnostics on dust and droplet transport should contribute to the improvement of fusion operations in terms of, such as impurity transport, implementation of liquid metal (lithium/tin) for inner-wall, radiation cooling, pellet transport etc. Those experiments seems to be achievable by the ability of the refurbished HT-6M.
