To condition the wall of the TJ-II vacuum vessel, a number of techniques is used.
Glow Discharge Cleaning
Glow discharge cleaning is routinely used at TJ-II. [1] [2]
Wall conditioning
Careful control of wall conditions is essential for successful operation. [3]
The walls can be coated by various materials, using a set of 4 evaporation ovens: two fixed and two mounted on retractable manipulators. TJ-II was the first stellarator to be operated with Lithium-coated walls.
