NSTX / NSTX-U
A leading spherical-tokamak experiment establishing low-aspect-ratio, high-beta physics.
- Type
- Spherical tokamak
- Relevance
- Breeder heritage
NSTX and its upgrade are spherical-tokamak experiments that established much of the low-aspect-ratio, high-beta physics Kronos's breeder relies on. HYPERION's beta target (βN = 1.532) sits within limits observed on such machines.
The spherical-tokamak database is the direct heritage of the Kronos breeder.
Common questions
What is NSTX and why is it relevant to Kronos?
NSTX (and its upgrade) is a spherical tokamak that demonstrated high beta at low aspect ratio — exactly the regime HYPERION uses. Its results underpin the breeder's βN = 1.532 choice.
How closely does Kronos follow it?
HYPERION runs comfortably within the no-wall beta limits observed on machines like NSTX, a deliberately conservative posture for a spherical tokamak at A = 2.5.
