Fusion center
（重定向自Fusion Centers）
A fusion center is an information sharing center, many of which were jointly created between 2003 and 2007 under the U.S. Department of Homeland Security and the Office of Justice Programs in the U.S. Department of Justice.
They are designed to promote information sharing at the federal level between agencies such as the Central Intelligence Agency (CIA), Federal Bureau of Investigation (FBI), U.S. Department of Justice, U.S. military, and state- and local-level government. As of July 2009, the U.S. Department of Homeland Security recognized at least 72 fusion centers. Fusion centers may also be affiliated with an Emergency Operations Center that responds in the event of a disaster.
