The Experimental Advanced Superconducting Tokamak (EAST, internal designation HT-7U) is an experimental superconducting tokamak magnetic fusion energy reactor in Hefei, China. The Hefei-based Institute of Plasma Physics is conducting the experiment for the Chinese Academy of Sciences. It has operated since 2006. It was later put under control of Hefei Institutes of Physical Science.
It is the first tokamak to employ superconducting toroidal and poloidal magnets. It aims for plasma pulses of up to 1000 seconds.
The project was proposed in 1996 and approved in 1998. According to a 2003 schedule, buildings and site facilities were to be constructed by 2003. Tokamak assembly was to take place from 2003 through 2005.
Construction was completed in March 2006 and on September 28, 2006, "first plasma" was achieved.
Operations - results
On September 28, 2006, "first plasma" was achieved.
In February 2007 the reactor sustained an electrical current of 250 kA for five seconds.
In February 2016, a plasma pulse was maintained for a record 102 seconds at approximately 50 million Kelvin.
China is a member of the ITER consortium, and EAST is a testbed for ITER technologies.
EAST was designed to test:
- Superconducting Niobium-titanium poloidal field magnets, making it the first tokamak with superconducting toroidal and poloidal magnets
- Non-inductive current drive
- Pulses of up to 1000 seconds with 0.5 MA plasma current
- Schemes for controlling plasma instabilities through real-time diagnostics
- Materials for diverters and plasma facing components
- Operation with βN = 2 and confinement factor H89 > 2
