Base Plate (top & Bottom) : These two plates form the support for the massive vacuum vessel and the magnets. For simplicity, these two parts are purely representational in nature in the TokoToy.

|
Support Pillar : The support pillars form part of the massive support structure of any Tokamak. Support structures play a very important role in suporting the massive weight of the tokamak as well as keeping the vacuum vessel and the magnets from moving while in operation in high magnetic field enviroments. Movements in the magnet or the vacuum vessel could disrupt the plasma, which is not desirable.

|
Vacuum Pump: The vacuum pumps in the Tokamak ensure that the vacuum vessel where the plasma is generated does not have any residual or impurities. The typical vacuum inside a tokamak vessel is typically of the order of 10−8 Torr.

Lower and Upper Poliodal Field Coils : The Poloidal Field Coils (PF coils) of the Tokamak shapes and positions the confined hot plasma to the centre of the Tokamak. A tokamak can have several of such coils in operation.

The Upper and Lower Poliodal Field Coils (Identical, one each)
|
Central Solenoid : The Central Solenoid plays multiple roles in the running of a Tokamak, some of which are to (a) Starup of the plasma (b) Provide helical magnetic field lines within the vacuum vessel (c) verical stability of the plasma
|
 |
The Central Solenoid (1 no)
|
Toriodal Field Coil : The Toriodal Field coil generates the magnetic field required to confine the hot plasma in the centre of the vaccum vessel so that it does not come in contact with the walls of the vacuum vessel. In large tokamaks, this coil can generate very strong, (10s of tesla) of magnetic field. The number of these coils can depend on the size of the Tokamak.

|
The Vacuum Vessel (Front and Back): The vacuum vessel of the tokamak is where the hot plasma is generated and confined in a fusion machine. This very important component of the Tokamak is built in the shape of a toriod and is encased with the TF coils. The vacuum vessel is connected to the vacuum pumps to remove the air from the vacuum vessel to fill it with the fusion fuel gases (D and T) at an optimum low pressure.

Plasma : Plasma is the heart of the magnetically confined fusion as this is what generates the high temeprature (~150 million degrees C) required for fusion to occur. However, this piece in the TokaToy is purely representational and only shows how the confined plasma is located inside the vacuum vessel.

 |
Plasma inside the tokamak
|
Windows on the Vaccum Vessel : Windows on the vacuum vessel give access to the plasma inside the vacuum vessel. This can be used for (a) Optical or radiowave observation of the plasma (b) To deliver electrical power, cooling etc to components inside the vacuum chamber.
