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 the lab began to deliver a stream of ever-improved devices, which could be produced in huge numbers by the US's industrial base. At its peak, the Rad Lab employed 4, 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 US held a leadership position in a number of microwave-related fields.
Among their notable products were the SCR , the finest gun-laying radar of the war, and the SCR , an airborne interception radar that became the standard late-war system for both US 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.
During the mid- and lates, radio systems for the detection and location of distant targets had been developed under great secrecy in the United States and Great Britain , as well as in several other nations, notably Germany , the USSR , and Japan. In , the U.
The potential advantages of operating such systems in the Ultra High Frequency UHF or microwave region were well known and vigorously pursued. One of these advantages was smaller antennas , a critical need for detection systems on aircraft.
The primary technical barrier to developing UHF systems was the lack of a usable source for generating high-power microwaves. In February , researchers John Randall and Harry Boot at Birmingham University in Great Britain built a resonant cavity magnetron to fill this need; it was quickly placed within the highest level of secrecy.
Shortly after this breakthrough, Britain's Prime Minister Winston Churchill and President Roosevelt agreed that the two nations would pool their technical secrets and jointly develop many urgently needed warfare technologies. At the initiation of this exchange in the late summer of , the Tizard Mission brought to America one of the first of the new magnetrons.
American researchers and officials were amazed at the magnetron, and the NDRC immediately started plans for manufacturing and incorporating the devices. The name 'Radiation Laboratory', selected by Loomis when he selected the building for it on the MIT campus, was intentionally deceptive,  albeit obliquely correct in that radar uses radiation in a portion of the electromagnetic spectrum.
It was chosen to imply the laboratory's mission was similar to that of the Ernest O. At the time, nuclear physics was regarded as relatively theoretical and inapplicable to military equipment, as this was before atomic bomb development had begun. Ernest Lawrence was an active participant in forming the Rad Lab and personally recruited many key members of the initial staff.
Most of the senior staff were Ph. They usually had no more than an academic knowledge of microwaves, and almost no background involving electronic hardware development. Their capability, however, to attack complex problems of almost any type was outstanding.
Later in life, nine members of the staff were recipients of the Nobel Prize for other accomplishments. The OSRD was given almost unlimited access to funding and resources, with the Rad Lab receiving a large share for radar research and development.
This was made simpler by Lawrence and Loomis being involved in all of these projects.
Rabi was the deputy director for scientific matters, and F. Wheeler Loomis no relation to Alfred Loomis was deputy director for administration.
Even before opening, the founders identified the first three projects for the Rad Lab. In the order of priority, these were 1 a cm detection system called Airborne Intercept or AI for fighter aircraft , 2 a cm gun-aiming system called Gun Laying or GL for anti-aircraft batteries, and 3 a long-range airborne radio navigation system.
To initiate the first two of these projects, the magnetron from Great Britain was used to build a cm " breadboard " set; this was tested successfully from the rooftop of Building 4 in early January All members of the initial staff were involved in this endeavor. Under Project 1 led by Edwin M. This, the first microwave radar built in America, was tested successfully in an aircraft on March 27, It was then taken to Great Britain by Taffy Bowen and tested in comparison with a cm set being developed there.
For the final system, the Rad Lab staff combined features from their own and the British set. It eventually became the SCR, used extensively by both the U. For Project 2, a 4-foot- and later 6-foot-wide 1. Also, this set would use an electro-mechanical computer called a Predictor-correlator to keep the antenna aimed at an acquired target. Ivan A. Getting served as the project leader. Being much more complicated than the Airborne Intercept and required to be very rugged for field use, an engineered GL was not completed until December This eventually was fielded as the ubiquitous SCR , first gaining attention by directing the anti-aircraft fire that downed the about 85 percent of German V-1 flying bombs "buzz bombs" attacking London.
Project 3, a long-range navigation system, was of particular interest to Great Britain. They had an existing hyperbolic navigation system, called GEE , but it was inadequate, in both range and accuracy, to support aircraft during bombing runs on distant targets in Europe. By the end of hostilities, about 30 percent of the Earth's surface was covered by LORAN stations and used by 75, aircraft and surface vessels. At the height of its activities, the Rad Lab employed nearly 4, people working in several countries.
Activities eventually encompassed physical electronics, electromagnetic properties of matter, microwave physics, and microwave communication principles, and the Rad Lab made fundamental advances in all of these fields. Half of the radars deployed by the U.
For the exchange of information, the Rad Lab established a branch operation in England, and a number of British scientists and engineers worked on assignments at the Rad Lab.
The resonant- cavity magnetron continued to evolve at the Rad Lab.
