The vacuum vessel is subdivided into four (4) sectors or quadrants, corresponding to the 4-fold symmetry of the machine (each sector being essentially identical). The enumeration of the sectors or quadrants (A through D) is shown in the top view of the machine. | The [[TJ-II:Vacuum system|vacuum vessel]] is subdivided into four (4) sectors or quadrants, corresponding to the 4-fold symmetry of the machine (each sector being essentially identical). The enumeration of the sectors or quadrants (A through D) is shown in the top view of the machine. | ||
Each sector is subdivided into eight segments. | Each sector is subdivided into eight segments. | ||
Each segment has two or three viewports, labelled 'TOP', 'BOTTOM', or 'SIDE'. | Each segment has two or three viewports, labelled 'TOP', 'BOTTOM', or 'SIDE'. | ||
Segments 1 and 8 in each sector have an additional tangential port, labelled 'TANG'. | |||

counterclockwise direction. | In the Experimental Hall, North is where the door to the Control Room is located. | ||
The toroidal angle φ is therefore zero between segment C8 and D1, and increases in the | |||
counterclockwise direction as seen from above. | |||
This definition of the toroidal angle coincides with the reference coordinate system used | |||
during the [[TJ-II:Construction|construction]] of [[TJ-II]]. | |||
