Bussard collector

Template:ShipClass ramscoop.

The Bussard collector, also known as a Bussard ramscoop or ramscoop, is a device usually attached to the forward end of a warp nacelle.

All Federation starships are equipped with Bussard collectors, which are positioned in the best line of sight to collect particles. Collection works best in regions where particle density is high like solar systems or nebulae.

The Bussard collector normally collects hydrogen, especially deuterium for fuel replenishment but can be reconfigured to collect various gases like sirillium and plasma particles.

In 2374, Seven of Nine determined that the collectors of an Template:ShipClass starship were less than optimal. She performed a series of modifications that enhanced them by twenty-three percent. (VOY: "Unforgettable")

A Bussard collector can also be reconfigured to expel gases or plasma. (TNG: "Samaritan Snare") Bussard collectors are not capable of producing nadion emissions. (VOY: "The Haunting of Deck Twelve") The Tosk variation of the Bussard collector was known as the arva node. (DS9: "Captive Pursuit")

Bussard collectors expeling gases

In 2365, the USS Enterprise-D's collectors were used to create a harmless pyrotechnic display against the Pakleds to recover Lieutenant Geordi La Forge by igniting released hydrogen. This event came to be known as a crimson force field. (TNG: "Samaritan Snare")

In 2367, the Enterprise-D released large quantities of hydrogen from its Bussard collectors to create a violent explosion. (TNG: "Night Terrors")

Galaxy class Bussard collector

In 2373, USS Voyager's collectors were used to gather the sirillium from a class 17 nebula. It was described that they would "cut through that nebula like ice cream scoops." (VOY: "Flashback") They were modified to gather plasma particles from an astral eddy. (VOY: "Real Life")

In 2375, Commander William Riker used the USS Enterprise-E's collectors to gather, and then vent, metreon gas against attacking Son'a vessels, a maneuver which Geordi nicknamed the Riker Maneuver. (Star Trek: Insurrection)

In 2376, USS Voyager's collectors were modified to gather deuterium from a J class nebula. (VOY: "Unforgettable", "The Haunting of Deck Twelve")

Background

According to the the Star Trek: The Next Generation Technical Manual, the main function of a Starfleet Bussard collector is to collect interstellar hydrogen atoms for fuel replenishment. The device consists of a set of coils which generate a magnetic field. Collected gases are compressed and stored into holding tanks.

The basic principles behind the Bussard collector came from Robert W. Bussard's design of the Bussard ramjet, a propulsion system meant for interstellar spaceflight.
