Radio Data System
Radio Data System (RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts. RDS standardizes several types of information transmitted, including time, station identification and program information. The standard began as a project of the European Broadcasting Union (EBU), but has since become an international standard of the International Electrotechnical Commission (IEC). Radio Broadcast Data System (RBDS) is the official name used for the U.S. version of RDS. The two standards are only slightly different, with receivers able to work with either system and only minor inconsistencies in the displayed data. Both versions carry data at 1,187.5 bits per second on a 57 kHz subcarrier, so there are exactly 48 cycles of subcarrier during every data bit. The RBDS/RDS subcarrier was set to the third harmonic of the 19 kHz FM stereo pilot tone to minimize interference and intermodulation between the data ...

Reflectance Difference Spectroscopy
Reflectance difference spectroscopy (RDS) is a spectroscopic technique which measures the difference in reflectance of two beams of light that are shone in normal incident on a surface with different linear polarizations. It is also known as reflectance anisotropy spectroscopy (RAS). It is calculated as: : RDS= 2 \frac, r \in \mathbb r_ and r_ are the reflectance in two different polarizations. The method was introduced in 1985 for the study optical properties of the cubic semiconductors silicon and germanium. Due to its high surface sensitivity and independence of ultra-high vacuum, its use has been expanded to in situ monitoring of epitaxial growth or the interaction of surfaces with adsorbates. To assign specific features in the signal to their origin in morphology and electronic structure, theoretical modelling by density functional theory Density-functional theory (DFT) is a computational quantum mechanical modelling method used in physics, chemistry and materials s ...

RDS-37
RDS-37 was the Soviet Union's first two-stage hydrogen bomb, first tested on 22 November 1955. The weapon had a nominal yield of approximately 3 megatons. It was scaled down to 1.6 megatons for the live test. Leading to the RDS-37 The RDS-37 was a reaction to the efforts of the United States. Previously, the Soviet Union allegedly used many of their spies in the U.S. to help them generate methods and ideas for the nuclear bomb. The creation of the hydrogen bomb required less usage of this method, although they still received help from some spies, most importantly, Klaus Fuchs. In 1945, the Soviet Union reached a decision to work on a design for a "super bomb". Also in 1945, Enrico Fermi gave lectures at Los Alamos discussing the fusion process. At the end of his lecture he stated "so far all schemes for the initiation of the super rerather vague". In the spring of 1946, Edward Teller set up a conference to assess all the information known about the hydrogen bomb. Klaus Fuc ...

RDS-6
Joe 4 was an American nickname for the first Soviet test of a thermonuclear weapon on August 12, 1953, that detonated with a force equivalent to 400 kilotons of TNT. The proper Soviet terminology for the warhead was RDS-6s, , . RDS-6 utilized a scheme in which fission and fusion fuel (lithium-6 deuteride) were " layered", a design known as the ''Sloika'' (russian: Слойка, links=no, named after a type of layered puff pastry) model in the Soviet Union. A ten-fold increase in explosive power was achieved by a combination of fusion and fission. A similar design was earlier theorized by Edward Teller, but never tested in the U.S., as the "Alarm Clock". Description The Soviet Union started studies of advanced nuclear bombs and a hydrogen bomb, code named RDS-6, in June 1948. The studies would be done by KB-11 (usually referred to as Arzamas-16, the name of the town) and FIAN. The first hydrogen bomb design was the Truba (russian: Труба, pipe/cylinder) (RDS-6t)). In March ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RDS-5
The RDS-5 (russian: РДС-5) was a plutonium based Soviet atomic bomb, probably using a hollow core. Two versions were made. The first version used 2 kg Pu-239 and was expected to yield 9.2 kilotons. The second version used only 0.8 kg Pu-239 Testing The two versions of the RDS-5 were tested during a series of 3 tests on September 3, 8 and 10 1953 in the Semipalatinsk test site. The test on September 3 (Joe 6.) was probably of the 2 kg version and achieved a yield of 5.8 kilotons (compared to the expected 9.2 kiloton yield). The test on September 8 was probably of the 0.8 kg version and yielded 1.6 kilotons.

RDS-4
RDS-4 (also known as ''Tatyana'') was a Soviet nuclear bomb that was first tested at Semipalatinsk Test Site, on August 23, 1953. The device weighed approximately . The device was approximately one-third the size of the RDS-3. The bomb was dropped from an IL-28 aircraft at an altitude of and exploded at , with a yield of 28 kt. The Soviet Union's first mass-produced tactical nuclear weapon was based on the RDS-4 and remained in service until 1966. It used a composite core of Pu-239 and 90% enriched U-235 and had a nominal yield of 30 kilotons. The bomb was delivered from a Tu-4 and Tu-16 aircraft. A tactical weapon based on the RDS-4 was also used on September 14, 1954 during Snowball military exercise near Totskoye (similar to Western Desert Rock exercises), when the bomb was dropped by the Tu-4 bomber (the reverse-engineered Boeing B-29). The purpose of this exercise was not to test the bomb itself, but the ability of using it while breaking through enemy defenses (presuma ...

RDS-3
RDS-3 was the third atomic bomb developed by the Soviet Union in 1951, after the famous RDS-1 and RDS-2. It was called ''Marya'' in the military. The bomb had a composite design with a plutonium core inside a uranium shell, providing an explosive power of 41.2 kilotons. The RDS-3T was a modernized version and the first mass-produced nuclear weapon by the Soviet Union. It was assigned to Long Range Aviation in 1953. Testing RDS-3 was tested on October 18, 1951, being air-dropped. It was the first such test of a nuclear device by the Soviets, known as Joe-3 in the West. It was detonated at an altitude of four hundred meters. The resulting flash could be seen from 170 kilometers away, and the sound heard from around the same distance. The footage of the test was filmed by an instrument tower 7.5 kilometers from ground zero.

RDS-2
The RDS-2 (Russian: РДС-2) was the second atomic bomb developed by the Soviet Union as an improved version of the RDS-1. It included new explosive lenses along with a new core design to decrease the probability of pre-detonation or 'fizzle'. The RDS-2 weighed approximately and had a diameter of 1.25 m. The RDS-2 was tested on September 24, 1951 and produced a 38.3 kiloton yield. It was detonated from the top of a tower thirty meters high. The detonation was controlled by a bomber flying over the testing site instead of the detonation being controlled by a ground control center.

RDS-1
The RDS-1 (russian: РДС-1), also known as Izdeliye 501 (device 501) and First Lightning (), was the nuclear bomb used in the Soviet Union's first nuclear weapon test. The United States assigned it the code-name Joe-1, in reference to Joseph Stalin. It was detonated on 29 August 1949 at 7:00 a.m., at the Semipalatinsk Test Site, Kazakh SSR, after top-secret research and development as part of the Soviet atomic bomb project. Description The weapon was designed at the Kurchatov Institute, then at the time officially known as "Laboratory № 2" but designated as the "office" or "base" in internal documents, starting in April 1946. Plutonium for the bomb was produced at the industrial complex Chelyabinsk-40. The RDS-1 explosive yield was 22 kilotons TNT equivalent, similar to the US Gadget and Fat Man bombs. At Lavrentiy Beria's insistence, the RDS-1 bomb was designed as an implosion type weapon, similar to the Fat Man bomb dropped on Nagasaki, Japan; RDS-1 also ...

Soviet Atomic Bomb Project
The Soviet atomic bomb project was the classified research and development program that was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during and after World War II. Although the Soviet scientific community discussed the possibility of an atomic bomb throughout the 1930s, going as far as making a concrete proposal to develop such a weapon in 1940, the full-scale program was not initiated and prioritized until Operation Barbarossa. Because of the conspicuous silence of the scientific publications on the subject of nuclear fission by German, American, and British scientists, Russian physicist Georgy Flyorov suspected that the Allied powers had secretly been developing a "superweapon" since 1939. Flyorov wrote a letter to Stalin urging him to start this program in 1942. Initial efforts were slowed due to the German invasion of the Soviet Union and remained largely composed of the intelligence gathering from the Soviet spy rings working in the U. ...
