Tokamak Energy, 173 Brook Drive, Milton Park, Oxon, OX14 4SD, UK 1. The field at the Tokamaks are the most advanced fusion concept in the world, but recent progress has been slow and we need to take an innovative approach to develop fusion faster. Defect tolerance 5. 3. found in systems codes and studies [16,17] and tokamak magnet design studies [18]. The Tokamak Energy HTS magnet development team answer questions from our followers on their work with high temperature superconductor materials and making high … ST25(HTS) In order to gain experience with constructing tokamaks using magnets made from HTS, Tokamak Energy constructed a small but complete tokamak. In 2015, the world's first tokamak with HTS magnets – Tokamak Energy's second reactor – demonstrated 29 hours of continuous plasma, which was a world record. SPARC will the pave the way for carbon-free, safe, limitless, fusion power. 2. 3.2. The HTS current leads for the ITER Tokamak are procured by the Chinese Domestic Agency through the Institute of Plasma Physics (ASIPP) in Hefei. Spherical Tokamak. 2. Characteristic magnet behaviour. Most importantly, HTS current leads—in a similar way to superconducting magnets—contribute to the positive energy balance of the ITER Tokamak. present. Tokamak Energy aims to accelerate the development of fusion energy by combining two emerging technologies – spherical tokamaks and high-temperature superconductors. ... ST25 HTS. ST40: 40cm plasma radius version. In parallel we are fast-track developing HTS magnet technology for use in our follow-up machine. For Tokamak Energy, miniaturisation will then be the goal. This compact, high-field tokamak will be built with HTS magnets, allowing for a smaller device than previous magnet technology. Quench - accompanying presentation Jeroen van Nugteren (JvN) 4. HTS allows much higher magnetic fields than would be possible from conventional superconductors, enabling a more compact tokamak design. present. energy confinement in STs has a stronger dependence on toroidal field compared to large aspect ratio devices •Tokamak Energy have extended ST scaling to include a size dependence , ℎ (ST,gyro−Bohm)∝ −1 ∗ −3 ∗ −0.53−0.17 −0.35 , ℎ (ST,gyro−Bohm)=0.21 0.54 0.91 −0.38 A ground-breaking fusion reactor built by Chinese scientists is underscoring Beijing's determination to be at the core of clean energy technology, as it eyes a fully-functioning plant by 2050. Oxfordshire-based Tokamak Energy is working on spherical tokamaks or reactors that use high temperature superconductors (HTS) to contain the plasma in a very strong magnetic field. All coils (toroidal and poloidal) are wound from YBCO HTS tape. HTS also allows the fusion magnets to operate at higher temperatures, greatly reducing the required cooling. Tokamak Energy's technology revolves around high temperature superconducting (HTS) magnets, which allow for relatively low-power and small-size devices, but high performance and potentially widespread commercial deployment. ST40. Spherical Tokamak. A key innovation is that the company combines spherical tokamaks with the latest generation of high temperature superconducting magnets (HTS). Then, in the 2010s, high temperature superconductor (HTS) materials became available as a reliable engineering material, fabricated into long tapes suitable for winding into magnets. Higher B: spatial resolving power ~B3 SMES: Energy Density B2 Small ST, Tokamak Energy, UK Magnet performance comparison. Credit: The Tokamak Energy HTS Magnet Team Simon Bradford, Trevor Husband, Rod Bateman, Chris Buckley, Tony Langtry, Marcel Kruip, Greg Brittles, Rob Slade, Bas van Nugteren Responsibilities include magnet design, manufacture and testing, project management and team leadership. ST25: The spherical tokamak (ST) with a 25cm outside radius of the plasma. HTS also allows the fusion magnets to operate at higher temperatures, greatly reducing the required cooling. Tokamak Energy has produced two laboratory prototypes, achieving a world first with the ST25 HTS, which demonstrated the use of high temperature superconductor (HTS) magnets. The factor 2 increase in the cost of current leads due to addition of (still relatively expensive) HTS material is more than offset by the cost savings for cryoplants and power savings during operation. Bas van Nugteren. Tokamak Energy is deliberately trying to tackle difficult engineering challenges as rapidly as possible, something HTS materials is helping us do. In 2015, ST25-HTS ran its magnets and sustained a plasma continuously for 29 hours. Supercond. Alun Down HTS Magnet Project Engineer at Tokamak Energy Ltd … This is the world’s first demonstration of a tokamak magnet where all the magnets are made from HTS. UK. 6. Currently, some large warships have their own nuclear fission plants – the other form of nuclear energy humankind has used for decades. All of the ST25 code is new and written specifically for this application; however, we can reuse the code in the ST25(HTS) and future iterations and take full advantage of the NI graphical system design benefits. Jonathan Carling, CEO at Tokamak Energy… HTS allows much higher magnetic fields than would be possible from conventional superconductors, enabling a more compact tokamak design. Tokamak Energy is working with Oxford Instruments to develop and demonstrate the world’s first tokamak with magnets made from high-temperature superconductors (HTS). “Our latest design, ST40, uses copper magnets but is much more of an engineering challenge as we are aiming for exceptionally strong magnetic fields, up to three Tesla at the centre of the plasma,” Kingham says. Fusion energy projects and start-ups around the world are pursuing fusion in different ways. Tokamak Energy. Bas van Nugteren HTS Magnet Development Engineer at Tokamak Energy Abingdon. 2012 to . SPARC is an important step to accelerate the development of commercial fusion energy. ST25-HTS is the first tokamak to use these superconductors for both sets of coils. Tokamak Energy. We can build a small tokamak quickly We can extend plasma pulse Long pulses feasible with HTS and RF (micro-wave) current drive A high magnetic field in a small tokamak is the key to compact fusion energy First patent application filed on fusion power from compact spherical tokamak with HTS magnets Tokamak Energy’s family tree. Tokamak Energy Ltd, UK, is developing spherical tokamaks using high temperature superconductor magnets as a possible route to fusion power using relatively small devices. A tokamak with HTS (for example, Rare-Earth Barium Copper Oxide REBCO)- would allow an increase in B T at the center of the plasma, over LTS technology, from ≈ 5.5T to more than 12T. “Saturated Mode” operation. Furthermore, an YBCO conductor structure suitable for a 10 GJ tokamak TF magnet is designed and the current carrying capacity is evaluated. HTS Cryogenic Engineer at Tokamak Energy Ltd England, United Kingdom. I lead a team of skilled engineers and technicians on several HTS magnet projects. By combining high-temperature superconducting (HTS) magnets with spherical tokamak technologies, the ST40 reactor is able to produce the perfect conditions for fusion power with plasma temperatures that are even hotter than the centre of the sun. Dr Rod Bateman, HTS Development Manager, tells us about his work in high temperature superconductor (HTS) magnet development and why it is so exciting for him to work at Tokamak Energy. In construction, due for high temperature testing starting spring 2017. The MIT Plasma Science & Fusion Center in collaboration with private fusion startup Commonwealth Fusion Systems (CFS). Tokamak Energy grew out of Culham Laboratory, home to JET - the world's most powerful tokamak - and the world's leading centre for magnetic fusion energy research. Alun Down. The following is a list of fusion energy projects pursued by organizations worldwide. In this paper, the application feasibility of HTS tapes on tokamak magnets is discussed and the existing four kinds of HTS high current conductors are summarized.
