Raygun

A very early example of a raygun is the Heat-Ray featured in H. G. Wells' novel The War of the Worlds (1898). Science fiction during the 1920s described death rays. Early science fiction often described or depicted raygun beams making bright light and loud noise like lightning or large electric arcs. According to The Encyclopedia of Science Fiction, the word "ray gun" was first used by Victor Rousseau Emanuel in 1917, in a passage from The Messiah of the Cylinder: All is not going well, Arnold: the ray-rods are emptying fast, and our attack upon the lower level of the wing has failed. Sanson has placed a ray-gun there. All depends on the air-scouts, and we must hold our positions until the battle-planes arrive. The variant "ray projector" was used by John W. Campbell in The Black Star Passes in 1930. using a raygun on the cover of Famous Funnies #209 Ray guns were so common on magazine covers during the Golden Age of Science Fiction that Campbell's Astounding was unusual for not depicting them. The term "ray gun" had already become cliché by the 1940s, in part due to association with the comic strips (and later film serials) Buck Rogers and Flash Gordon. Soon after the invention of lasers during 1960, such devices became briefly fashionable as a directed-energy weapon for science fiction stories. For instance, characters of the Lost in Space TV series (1965–1968) and of the Star Trek pilot episode "The Cage" (1964) carried handheld laser weapons. By the late 1960s and 1970s, as the laser's limits as a weapon became evident, rayguns were dubbed "phasers" (for Star Trek), "blasters" (Star Wars), "pulse rifles", "plasma rifles", and so forth. ==Function==

Ray guns as described by science fiction do not have the disadvantages that have, so far, made directed-energy weapons largely impractical as weapons in real life, needing a suspension of disbelief by a technologically educated audience: • Ray guns draw seemingly limitless power from often unspecified sources. In contrast to their real-world counterparts, the batteries or power packs of even handheld weapons are minute, durable, and do not seem to need frequent recharging. • Ray guns in movies are often shown as shooting discrete pulses of energy visible from off-axis, traveling slowly enough for people to see them emerge, or even for the target to evade them, Michio Kaku dedicated the third chapter of his 2008 book Physics of the Impossible to the problem of ray guns and similar directed-energy weapons. He concluded that handheld weapons of the kind featured in a typical science fiction setting were a "Class I impossibility", meaning that they were not scientifically viable at the time of the book's publication but could become viable within the space of a century or two assuming that certain advances in material science and nanotechnology were made. Attempts to create a basic ray gun-type weapon today, Kaku claimed, would require either a portable power pack on the order of a "minature hydrogen bomb, which might destroy you as well as the target" or a cabled connection to a stationary pack, while any currently available lasing material would be insufficiently stable for handheld use. Kaku further stated that extremely powerful rayguns such as the Death Star's primary weapon in the Star Wars franchise could theoretically function either as a nuclear-fired X-ray laser or as a gamma ray burster, but said Death Star-type ordnance represented a "Class II impossibility" that would require thousands or even millions of years to be realistically developed. Ethan Siegel, when assessing Star Trek's "plasma rifle" and "phaser" ray guns in his 2017 book Treknology, drew parallels to directed-energy weapons that were in United States use as of 2017 and to electroshock weapons (including electrolasers) respectively, and said that the greatest current obstacle to making phasers a reality was ensuring that an eventual weapon could conduct its energy without being dependent on an atmospheric medium or on physical contact with the intended target. Rayguns by their various names have various sizes and forms: pistol-like; two-handed (often called a rifle); mounted on a vehicle; artillery-sized mounted on a spaceship or space base or asteroid or planet. Rayguns have a great variety of shapes and sizes, according to the imagination of the story writers or movie prop makers. Most pistol rayguns have a conventional grip and trigger but some (e.g. Star Trek: The Next Generation phasers) do not. Sometimes the end of the barrel expands into a shield, as if to protect the user from back-flash from the emitted beam. ==Types==

The "rays" the guns use vary. They are sometimes equated to real life technologies such as: • lasers • particle beams, e.g. protons and/or neutrons from the proton packs in Ghostbusters • plasma, e.g. plasma rifles, Star Wars "Blasters" Alternately, the weapon mechanics can be purely fictional. Fictional ray types include: • "Minovsky particles" in the Gundam anime series • "Rapid Nadion particles" utilized by the phasers in Star Trek ==List of rayguns==

The following is a list of notable rayguns. Literature 's Lensman novels • Heat-Ray, weapons used by the Martians in the novel The War of the Worlds by H. G. Wells • The Garin Death Ray, title weapon in The Hyperboloid of Engineer Garin (1927): "hyperboloid", a highly concentrated collimated light beam weapon • Lasgun, a laser projector from the Dune series of books Film and television • Proton pack, an energy weapon used for weakening ghosts and aiding in capturing them in the film Ghostbusters • Phasers, disruptors, and plasma rifles and cannons are a few of the many weapons of Star Trek. • Blasters, standard weapons of the Star Wars universe. Games • BFG, a large gun in the Doom and Quake series of games ==See also==
