Gravitation chamber was a special room that was present in the System Lord Ba'al's fortress.


The gravitation chamber is a small room capable of producing artificial gravity, effectively making the wall opposite the door the floor. This ability may be turned on or off; when off, one may enter the room normally. By turning the artificial gravity on once someone has entered the room, the room functions as an exit-less prison.

An arrow on the wall rotates to point towards the room's "floor".

When Jack O'Neill was imprisoned and tortured by Ba'al, he was kept in a Gravitation chamber between interrogations, where he was kept company and comforted by the ascended Daniel Jackson. (SG1: "Abyss")

After Lord Yu's attack, the chambers' gravity fields lost power which allowed O'Neill's escape. As a result, when Major Samantha Carter was captured a year later during a raid on the facility, the Jaffa were forced to improvise with a heavy grate to lock the chamber instead.
