Abstract

The LM26 device has achieved a peak electron temperature of Te = 1180 ± 65 eV as measured by filtered X-ray diodes, supported by adjacent Thomson scattering measurements of Te = 1090 ± 40 eV, with a deuterium ion temperature of Ti = 459 ± 33 eV as inferred from neutron yield. LM26 compresses a spherical tokamak plasma inside an initially 1.76 m diameter solid lithium liner imploded by theta-pinch coils. Radial compression by a factor of 2.75 increases Te over fivefold, while Ti increases as much as twofold. The integrated observation of magnetic flux compression, electron heating, ion heating, and neutron production in a magnetized plasma compressed by a large lithium liner is an important milestone for magnetized target fusion
