Relative Dimensional Stabilizers
The primary and secondary Relative Trans-Dimensional Stabilizers (RDS) are inside the control assemblies of their respective Control Rooms. They are accessed from the underside of the console. They are responsible for creating the size, shape and form of a TARDIS's interior. The sphere of the Core Service Module is surrounded by a grid of matter control projectors which the Dimensional Stabilizers use to maintain the Module. Because they allow the operator to cross three dimensional barriers a TARDIS cannot travel the vortex without them. The field created by the stabilizers are also an essential part of the Temporal Grace effect. Because of their role as an interface between the four dimensional TARDIS and its three dimensional crew the Relative Dimensional Stabilizers[/ext are essential for the TARDIS to understand the desire of its operator.
Monitoring and controlling the RDS takes up more of the Artron Mainframe's processing power than any other function, leaving only 5% of the processing capacity for other functions. Vintage Mark I consoles have very primitive Stabilizers in comparison to later models. While the Primary RDS can handle normal operations when the TARDIS is fully materialized the secondary stabilizers can be cored in to operation if the operator desires.
The Relative Dimensional Stabilizers cycle continuously when a TARDIS is in flight and can sometimes be faintly heard in the Control Room. The sound is clearly audible on the exterior when a TARDIS materializes or dematerializes. This sound is slightly different for different types of TARDIS. If the TARDIS is badly in need of an overhaul the Dimensional Stabilizers will be unbalanced and sound different almost every time there is a materialization.
The Dimensional Stabilizers can be used to fix some kinds of space-time anomalies. They can seal cracks in Time that lead to Parallel Universes, repair damage to the time lines, and act as temporal de-crystallizers It should be noted that the TARDIS's exo-shell can also be used to temporarily plug some types of holes in space-time. In an emergency (and using codes available only to the Lord President) the Stabilizer can be used to control Gallifrey's defence barriers.
Like many pieces of Time Lord technology, the stabilizers will interface with alien technology automatically. The stabilizer can use sonic vibrations at specific frequencies to alter the space between atoms – effectively altering the size of people or objects with only a few simple modifications. The possible compression factor can be up to a million or possibly even higher. The Relative Dimensional Stabilizer's generator appears to be able to bank matter (or at least mass and inertia) in some sort of a holding account. The result is that even though the number of atoms remains the same the mass and inertia is reduced an object, or person's, dimensions are compressed. A skilled technician can reverse such compression with a sonic screwdriver - but this will take a great deal of time. This same frequency based technique appears to be used by the Master's Tissue Compression Eliminator and Laser
Removal of the Stabilizers' Dimensional Control shrinks the interior micro-universe (all the rooms within it) down to the size of doll house (see illustration). Dimensional Stabilizers can suffer failures of synaptic adhesion or their chronostat can fail. The stabilizers are controlled by a series of blue buttons on the console. They should all be engaged to ensure a smooth flight. If a TARDIS dematerializes without the Stabilizers being properly reset, then the internal gravity will go into a "spin." Under such circumstance the operator should pull the manual override for the stabilizer that is found behind a small hatch at the base of the console's stem. If the Stabilizers are completely disabled, then the life support systems become inoperative.
If the Dimensional Control should fail while the crew is not on board, they will be unable to enter the TARDIS to perform repairs. In this case, it is recommended that the operator access the Scanner Circuits from outside the capsule and visually link the dimensional integrator circuits through the scanner linkages to act as a temporary stabilizer. This will enlarge the interior enough that proper repairs can be made. In an emergency, the Gravitic Anomaliser from the Force Field Generator can be used as a dimensional stabilizer if the main stabilizer is fused. Because Warp Drives are designed to also bank matter to achieve light speed travel, it is possible to construct a primitive Relative Dimensional Stabilizer out of the drive circuits of a space ship equipped with a warp drive using the following procedures:
- Deactivate all drive circuits
- Reverse the polarity of the main warp feeds
- Regrade the deoscillation digretic synthesizers by minus 10 points
- Realign the maxivectormeter on drags so they cross connect with the radia-bicentric anodes
- Switch the conceptual geometer from analogue to digital mode
- Begin triggering feedback responses from the conceptual geometer until a reading of 57-836 results
- Reactivate all drive circuits
