DTU Tokamak

Introduction

The Spherical Tokamak NORTH is a small tokamak device installed at DTU during the fall 2018 with first plasma in the March 2019. The tokamak project is a collaboration between DTU and the British company Tokamak Energy who constructed the device in Oxfordshire. The device is the first Tokamak experiment at DTU and will contribute to the understanding of plasma dynamics with the ultimate goal of harvesting the clean energy of fusion power.

Spherical Tokamaks

A spherical tokamak is a compact version of the original tokamak developed in the former Sovjet Union. Tokamaks can confine plasma with temperatures above 200.000.000 C, which is 10 times the high than the temperature in the centre of the Sun. The warm plasma is confined using advanced magnetic fields and the high temperatures are achieved by heating with waves and neutral beams.

Technical specifications of NORTH

The NORTH tokamak is a small scale tokamak with a radius of 25 cm and a central magnetic field up to 0.3 T. The plasma is heating using two 3 kW magnetrons operating at 2.45 GHz. Presently, only few diagnostic are installed on the device. The goal is to equip the device with plasma diagnostics in order to measure density, temperature and general wave propagation during 2019 and start a dedicated research program in late 2019 or early 2020. The aim is to involve the students at DTU to construct palsma diagnostics and to assist in the operation of the device.

The device is presently located in the basement of DTU building 309.
