[edit] Geography
Pokhran is located at .[1] It has an average elevation of 233 metres (764 feet).
Surrounded by rocky, sandy and five salt ranges, Pokaran means “the place of five mirages”. It is en route both from Jodhpur to Jaislamer and Bikaner to Jaislamer.
[edit] Demographics
As of 2001 India census[2], Pokhran had a population of 19,186. Males constitute 55% of the population and females 45%. Pokhran has an average literacy rate of 56%, lower than the national average of 59.5%: male literacy is 68%, and female literacy is 41%. In Pokhran, 19% of the population is under 6 years of age.
[edit] Landmarks
Fort Pokaran, the 14th century citadel also known as “Balagarh”, stands amidst the Thar Desert. This monument is the premier fort of the chief of the Champawats, the clan of Rathores of the state of Marwar-Jodhpur.
The famous, touristic city and fort of Jaisalmer is a couple of hours away by road.
[edit] Nuclear test site
Pokhran shot into international limelight on September 7, 1972 when the then Indian Prime Minister Indira Gandhi gave authorization to the scientists at the Bhabha Atomic Research Centre (BARC), Trombay to detonate an indegenously designed nuclear device. Throughout its development, the device was formally called the "Peaceful Nuclear Explosive", but it was usually referred to as the Smiling Buddha.
The head of the development team was Raja Ramanna. Other key members were P.K. Iyengar, Rajagopala Chidambaram, and Nagapattinam Sambasiva Venkatesan. The project employed no more than 75 scientists and engineers from 1967-1974. Keeping it small served to aid in the preservation of secrecy, according to the researcher Jeffrey Richelson.[1]
The device used a high explosive implosion system, developed at the Defence Research and Development Organisation (DRDO)'s Terminal Ballistics Research Laboratory (TBRL), Chandigarh, based on the American design from World War II. But the Indian design was simpler and less sophisticated than the American system. The 6 kg of plutonium came from the CIRUS reactor at BARC, Trombay, Mumbai (then Bombay). The neutron initiator was a Polonium-Beryllium type (again like those used in early U.S. bombs of the Fat Man type) code-named "Flower." The complete core was assembled in Trombay before transportation to the test site.
The fully assembled device had a hexagonal cross section, 1.25 m in diameter and weighed 1400 kg. The device was detonated at 8.05 a.m. in a shaft 107 m under the army Pokhran test range in the Thar Desert (or Great Indian Desert), Rajasthan. Coodinates of the crater are [show location on an interactive map] 27°05′42″N 71°45′11″E / 27.095, 71.753. Officially the yield was reported at 12 kt, though outside estimates of the yield vary from 2 kt to 20 kt. Pokhran is the test site for India's nuclear program. The Atomic Energy Commission of India detonated its first underground nuclear weapon there on May 18, 1974. The Indian government, however, declared that it was not going to make nuclear weapons even though it had acquired the capacity to do so. It claimed that the Pokhran explosion was an effort to harness atomic energy for peaceful purposes and to make India self-reliant in nuclear technology, but subsequently, India conducted five nuclear tests on May 11 and May 13, 1998. Since then, India has declared a moratorium on the testing.
