Nuclear News 40 under 40: The wait is over
Following the enthusiastic response from the nuclear community in 2024 for the inaugural NN 40 under 40, the Nuclear News team knew we had to take up the difficult task in 2025 of turning it into a recurring annual issue—though there was plenty of uncertainty as to how the community would receive a second iteration this year. That uncertainty was unfounded, clearly, as the tight-knit nuclear community embraced the chance to celebrate the up-and-coming generation of scientists, engineers, and policy makers who are working to grow the influence of this oft misunderstood technology.

Plasma start-up experiments without using inductive field have been performed on the TST-2 spherical tokamak device. A low power ECH (2.45GHz/4kW) and a medium power High Harmonic Fast Wave (HHFW) (21MHz/up to 50kW) were used. Comparisons of various operational parameters were carried out to find the optimum conditions for the toroidal and the poloidal field strengths, poloidal field configurations, ECH power and HHFW power. Using only ECH, currents up to about 0.4 kA were generated. Current increments by up to 0.4 kA were observed when we apply HHFW to ECH plasmas.
