Event: European Physical Society Plasma Physics Conference 2026 (June 29, 2026 - July 3, 2026) Location: EICC, Edinburgh (150 Morrison St, Edinburgh EH3 8EE) Contribution Type: Poster Presentation Track: Magnetic Confinement Fusion (MCF): Plasma Diagnostics and Data Analysis (MCF) Duration: 20m LM26 is a large-scale magnetized target fusion (MTF) experiment built to demonstrate that compressional heating of a spherical tokamak plasma can achieve fusion conditions. A coaxial helicity injector forms a magnetized plasma in a 7 cm thick cylindrical lithium liner inside a composite chamber. A surrounding 36-turn theta-pinch coil generates a strong magnetic field to symmetrically compress the liner and the deuterium plasma it contains in less than 4 milliseconds. This is done without damaging any major vessel structures, allowing the device to be rapidly restored for service. The next milestone of the LM26 project is to achieve 1 keV in plasma temperature and increase the plasma density by an order of magnitude through compressional heating. To assess plasma properties and the evolution of compression dynamics, a comprehensive suite of diagnostics is employed. These include AXUV electron temperature diagnostics, a dual-color interferometer system, visible and UV ion Doppler spectrometers, AXUV bolometers, neutron scintillators, high-speed imaging, liner motion diagnostics, and magnetic sensors. This poster provides an overview of the LM26 machine, with a special focus on the composite vacuum vessel, trajectory of the solid lithium liner, and diagnostic coverage.
