Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

In the Tohoku University Heliac (TU-Heliac), hot-cathode biasing experiment has been carried out. Poloidal Mach number exceeded unity, and reached 5 (supersonic regime). Increase of the electron density and decrease of the impurity influx were observed. It is important to study the anomalous transport for evaluation of the improvement. Then potential and density fluctuation (~600 kHz) measurement system were installed to the TU-Heliac. Characteristics of the fluctuations in the hot-cathode-biased supersonic plasma were measured. The fluctuation of (i) low frequency band (<10 kHz) and (ii) high frequency band (100~300 kHz) had large power spectra. The fluctuations between these bands (10~100 kHz) were suppressed. The potential fluctuation level was larger more than one order of the density fluctuation level in the low frequency band (<10 kHz), and comparable to the density fluctuation level in the high frequency band (100~300 kHz).
