Trigger (particle physics)

In particle physics, a trigger is a system that uses criteria to rapidly decide which events in a particle detector to keep when only a small fraction of the total can be recorded. Trigger systems are necessary due to real-world limitations in computing power, data storage capacity and rates. Since experiments are typically searching for "interesting" events (such as decays of rare particles) that occur at a relatively low rate, trigger systems are used to identify the events that should be recorded for later analysis. Current accelerators have event rates greater than 1 MHz and trigger rates that can be below 10 Hz. The ratio of the trigger rate to the event rate is referred to as the selectivity of the trigger. For example, the Large Hadron Collider (LHC) has an event rate of 40 MHz (4·10 Hz), and the Higgs boson is expected to be produced there at a rate of roughly 1 Hz. The LHC detectors can manage to permanently store a few hundred events per second. Therefore the minimum selectivity required is 10, with much stricter requirements for the data analysis afterwards.

Trigger (firearms)

A trigger is a mechanism that actuates the firing sequence of a firearm or crossbow; a trigger may also start another mechanism such as a trap or a quick release. A small amount of energy applied to the trigger causes the release of much more energy.

In "double action" firearm designs, the trigger is also used to cock the firearm - and there are many designs where the trigger is used for a range of other functions. Although triggers usually consist of a lever actuated by the index finger, some such as the M2 Browning machine gun use the thumb, and others like the Springfield Armory M6 Scout use a "squeeze-bar trigger."

Trigger (guitar)

Trigger is a Martin N-20 nylon-string classical acoustic guitar used by country music singer-songwriter Willie Nelson. Early in his career, Nelson tested several guitars by different companies. After one of his guitars was destroyed in 1969, he purchased the Martin guitar.

Trigger (film)

Trigger is a Canadian comedy-drama film, released in 2010. Directed by Bruce McDonald, the film stars Molly Parker and Tracy Wright as Kat and Vic, former rock stars reuniting their band Trigger for the first time since their retirement.

The film was originally planned in the late 1990s as a companion film to McDonald's Hard Core Logo, which would have starred Hugh Dillon and Callum Keith Rennie. However, work on the film remained dormant until McDonald and screenwriter Daniel MacIvor decided to rewrite their original screenplay to be about two women instead. Rennie does, however, appear in the film as his Hard Core Logo character Billy Tallent.

The film's cast also includes Daniel MacIvor, Don McKellar, Sarah Polley, Lenore Zann, Carole Pope and Julian Richings. Brendan Canning of Broken Social Scene wrote the film's score.

Wright was undergoing treatment for pancreatic cancer during the film's production. It was the last film she completed before her death.

Trigger (drums)

In drumming, a trigger is an electronic transducer that can be attached to a drum, cymbal or other instrument to enable it to control an electronic drum unit or similar device.

Specialised triggers are produced for specific instruments. A snare drum trigger, for example, needs two channels, one each for the rim and head, while a tom-tom drum trigger needs only to register strokes to the drum head.

Drum triggers gained great attention in the beginning of the 1990s, being extensively used on bass drums in metal music.

The advantage of using drum triggers is that potential problems associated with using microphones can be overcome by triggering pre-recorded samples. It is commonly quoted that less effort is required from the drummer when using drum triggers. The drum module to which the trigger is connected can be adjusted to accommodate a range of volumes, thus preserving the dynamic range of the drummer's playing. Triggers have a greater use in live performances than in studio recordings, since some drummers dislike the processed triggered sound, labelled by some as artificial.

Trigger (Porno Graffitti album)

Trigger is the eighth studio album by the Japanese pop-rock band Porno Graffitti. It was released on March 24, 2010 and was ranked first in the Oricon chart during 2010.
