- The Radiation Laboratory, commonly called the Rad Lab, was a microwave and radar research laboratory located at the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts. It was first created in October 1940 and operated until 31 December 1945 when its functions were dispersed to industry, other departments within MIT, and in 1951, the newly formed MIT Lincoln Laboratory. The use of microwaves for various radio and radar uses was highly desired before the war, but existing microwave devices like the klystron were far too low powered to be useful. Alfred Lee Loomis, a millionaire and physicist who headed his own private laboratory, organized the Microwave Committee to consider these devices and look for improvements. In early 1940, Winston Churchill organized what became the Tizard Mission to introduce U.S. researchers to several new technologies the UK had been developing. Among these was the cavity magnetron, a leap forward in the creation of microwaves that made them practical for the first time. Loomis arranged for funding under the National Defense Research Committee (NDRC) and reorganized the Microwave Committee at MIT to study the magnetron and radar technology in general. Lee A. DuBridge served as the Rad Lab director. The lab rapidly expanded, and within months was larger than the UK's efforts which had been running for several years by this point. By 1943 the lab began to deliver a stream of ever-improved devices, which could be produced in huge numbers by the U.S.'s industrial base. At its peak, the Rad Lab employed 4,000 at MIT and several other labs around the world, and designed half of all the radar systems used during the war. By the end of the war, the U.S. held a leadership position in a number of microwave-related fields. Among their notable products were the SCR-584, the finest gun-laying radar of the war, and the SCR-720, an airborne interception radar that became the standard late-war system for both U.S. and UK night fighters. They also developed the H2X, a version of the British H2S bombing radar that operated at shorter wavelengths in the X band. The Rad Lab also developed Loran-A, the first worldwide radio navigation system, which originally was known as "LRN" for Loomis Radio Navigation. (en)

Esta instalação foi responsável pelo desenvolvimento da maioria dos radares de microondas utilizados pelos Estados Unidos durante a Segunda Guerra Mundial, incluindo o usado para bombardeio e as melhorias subsequentes à tecnologia inicial desse aparelho. O Rad Lab também desenvolveu o Loran-A, o primeiro sistema mundial de radionavegação, originalmente conhecido como "LRN" para Loomis Radio Navigation, em homenagem a Alfred Lee Loomis, que o inventou e desempenhou um papel crucial na pesquisa e desenvolvimento militar durante a Segunda Guerra. Permaneceu como o sistema de navegação de longo alcance mais utilizado até ser gradualmente substituído pelo Loran-C. O Loran-A foi descontinuado pelos Estados Unidos em 1980. (pt)
