Reconstruction of soft x-ray emission in MAST Upgrade. (2024)
Journal Article
Steward, B. A., Cecconello, M., & Bowman, C. (2024). Reconstruction of soft x-ray emission in MAST Upgrade. Review of Scientific Instruments, 95(12), Article 123508. https://doi.org/10.1063/5.0219168

Understanding the confinement of fast ions is crucial for plasma heating and non-inductive current drive, i.e., for the operation of a fusion reactor. Interactions between fast ions and magnetohydrodynamic instabilities can reduce the performance of... Read More about Reconstruction of soft x-ray emission in MAST Upgrade..

Journal Article
Dreval, M., Oliver, H., Sharapov, S., Rivero-Rodriguez, J., Fitzgerald, M., Michael, C., Ochoukov, R., Velarde, L., Cecconello, M., & Ryan, D. (2025). Observation of bi-directional global Alfvén eigenmodes in the MAST-U tokamak. Nuclear Fusion, 65(1), Article 016043. https://doi.org/10.1088/1741-4326/ad9849

The first observations and classification of deuterium beam-driven sub-cyclotron frequency range Alfvén eigenmodes (AEs) are presented for the MAST-Upgrade tokamak. Sets of observed eigenmodes are separated in frequency by approximately 200 kHz. We o... Read More about Observation of bi-directional global Alfvén eigenmodes in the MAST-U tokamak.
