The walls can be coated by various materials, using a set of 4 evaporation ovens: two fixed and two mounted on retractable manipulators. | 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 | In the course of time, TJ-II has been operated with the following types of wall: | ||
