In end of Nov, researchers were working in the “huge donut” - EAST equipment. This is how it looks from inside.
Their work, which started from August this year, focused on the maintenance and upgrading of the internal components and subsystems of EAST to further improve its performance.
Researchers and engineers were checking, testing and cleaning. The whole procedure, which is a must before another run of EAST experiment, needs much patience and meticulousness.
