Unveiling Fusion Secrets: High-Tech Analyzer for Tokamak Research

Industry: This paper presents the development of a low-energy neutral particle analyzer
(LENPA) for the Experimental Advanced Superconducting Tokamak (EAST). It is crucial for
industries involved in fusion energy research and reactor development.

Challenge: Understanding how neutral particles affect the first wall of a tokamak reactor is
vital. The challenge addressed here is to develop a specialized analyzer, LENPA, capable of
accurately measuring these particles’ energy and flux.

Extraordinary Aspects of the Paper: An extraordinary aspect of this paper is the innovative
design and implementation of the LENPA system for EAST. The use of a slotted rotating disc to
gate neutral outflux, along with precise detection mechanisms utilizing electron multipliers and
UV photon projections, showcases advanced engineering. The integration of GaGe digitizers
allows for high-speed data acquisition crucial for fusion reactor research, facilitating better
predictions for future reactors like ITER and China Fusion Engineering Test Reactor (CFETR).
