Ivy Mike was the codename given to the first test of a thermonuclear device, in which part of the explosive yield comes from nuclear fusion. The device was the first full test of the Teller-Ulam design , a staged fusion bomb, and was the first successful test of a hydrogen bomb. Due to its physical size and fusion fuel type cryogenic liquid deuterium , the Mike device was not suitable for use as a weapon; it was intended as an extremely conservative experiment to validate the concepts used for multi-megaton detonations. A simplified and lightened bomb version the EC was prepared, and scheduled to be tested in operation Castle Yankee , as a backup in case the non-cryogenic "Shrimp" fusion device tested in Castle Bravo failed to work; that test was cancelled when the Bravo device was tested successfully, making the cryogenic designs obsolete.

It was the first full test of the Teller—Ulam design , a staged fusion device. Due to its physical size and fusion fuel type cryogenic liquid deuterium , the "Mike" device was not suitable for use as a deliverable weapon. It was intended as a "technically conservative" proof of concept experiment to validate the concepts used for multi- megaton detonations. As a result of the collection of samples from the explosion by U. Air force pilots one of whom died in the process , scientists found traces of the isotopes plutonium and plutonium , and confirmed the existence of the predicted but undiscovered elements einsteinium and fermium. Beginning with the Teller—Ulam breakthrough in March , there was steady progress made on the issues involved in a thermonuclear explosion and there were additional resources devoted to staging, and political pressure towards seeing, an actual test of a hydrogen bomb. Truman a model of what the Ivy Mike device would look like; the test was set for November 1,
Preparations for the Shot
Ivy Mike Test: Mike Time: The device was designed by the Panda Committee directed by J. Carson Mark at Los Alamos Teller declined to play a role in its development. The Running down the center of the Dewar was a plutonium "spark plug" rod to ignite the fusion reaction. The inside surface of the casing was lined with sheets of lead and polyethylene to form the radiation channel that conducted heat from the primary to the secondary. The entire device weighed 82 tons.
Scientists had to work faster and harder in order the meet the short deadline to complete the weapon, but their work paid off when "Mike" was successfully completed on the target date. The device was strictly an experimental, prototype design and not a deliverable weapon: standing over 20 ft. Its explosion yielded Truman had initially tried to create a media blackout about the test-hoping it would not become an issue in the upcoming presidential election-but on January 7, , Truman announced the development of the hydrogen bomb to the world as hints and speculations of it were already beginning to emerge in the press. The next task was building a deliverable thermonuclear weapon, which would require accumulating a sufficient quantity of lithium The minimum required quantity of lithium-6 would not be stockpiled until , delaying the project still further.
