Wendelstein 7-X Achieves Breakthrough Performance Milestone in Nuclear Fusion Research
- The Wendelstein 7-X (W7-X) stellarator achieves a groundbreaking leap in fusion power research by setting a new global benchmark for plasma performance.
- W7-X, the largest stellarator experiment globally, sustains a record-breaking triple product for 43 seconds, surpassing other magnetic confinement devices.
- The triple product combines ion particle density, ion temperature, and energy confinement time, critical for achieving net energy gain from fusion reactions.
- W7-X's achievement is a paradigm shift, as it surpasses past benchmarks set by tokamaks in extended plasma discharges.
- Integration of an advanced pellet injector system from Oak Ridge National Laboratory enables sustained plasma fueling and refueling in real time.
- Precise pellet fueling synchronization and electron cyclotron resonance heating raise plasma temperatures to over 30 million degrees Celsius.
- Plasma diagnostics confirm W7-X's unprecedented triple product achievement and milestone in total energy turnover during the OP 2.3 campaign.
- By reducing magnetic field strength, W7-X reaches high plasma pressure ratios crucial for future fusion power, emphasizing stellarator potential.
- The international collaboration behind W7-X's success advances stellarators closer to practical fusion power realization.
- W7-X's flexible pellet injector operation paves the way for sustained plasma pulses, aligning with future fusion reactor requirements and breaking traditional barriers.
