A space-time attenuator is a device that generates a field to block electricity, GPS signals, and consciousness transfer within a certain radius - effectively making the user invisible to observing entities in the future. (S1E12: Grace)
Properties[]
The precise means of achieving the signal blackout effect is unknown for Traveler-constructed attenuators, but Vincent Ingram's device appears to be a basic version. Its functioning is achieved with deuterium oxide, slowing the movement of neutrons, and it is assured to be non-radioactive. (S2E01: Ave Machina)
Only wireless signals are blocked, as any other electronics within the field can work normally. Computers and such can still send and receive information to/from the outside through hard-wired connections. (S1E11: Marcy, S3E10: Protocol Omega)
Usage[]
Shortly after coming to the 21st, Ellis puts up a space-time attenuator to hide his activities on a farm, securing the area within a 100-yard radius. He turns it off after accidentally shooting Grace Day and Trevor Holden, but the Director immediately uses him as a messenger to order the destruction of the quantum frame he just assembled, countermanding its own previous order to make it. (S1E12: Grace)
Vincent Ingram's most recent personal residence has a space-time attenuator built into the heating system, following the two incidents the Director discovered his whereabouts. (S2E01: Ave Machina) However, when Taylor Ingram strays too far from its bounds, he is turned into a messenger ordering Vincent to stop his impending assault on the Core Traveler Team. (S2E03: Jacob)
During their assassination attempt on Anna Hamilton, the future 53rd President of the United States, the Faction deploys a portable device to prevent the Director from seeing them. Trevor bombs the device with a grenade, resulting in the overwrite of all remaining hostiles. (S2E10: 21C)
With the exposure of the Traveler program to government agencies, The FBI starts developing precautions against this potential threat. One of which is their own version of the attenuator, kept under guard below the operations room of a non-Traveler task force assigned to monitor Traveler activities. FBI Director Stevenson and agent Joanne Yates question Grant MacLaren in this room regarding Protocol Omega and the three nuclear devices that had been detonated in London, Moscow, and Shanghai. However, Stevenson is overwritten by Faction in the elevator just outside the room, suggesting the attenuator's field does not extend there or the device has been disabled. (S3E10: Protocol Omega)
