Camp X-Ray was a temporary detention facility at the Guantanamo Bay detention camp of Joint Task Force Guantanamo on the Guantanamo Bay Naval Base.The first twenty detainees arrived at Guantanamo on 11 January 2002.It was named Camp X-Ray because various temporary camps in the station were named sequentially from the beginning and then from the end of the NATO phonetic alphabet. The legal status of detainees at the camp, as well as government processes for trying their cases, has been a significant source of controversy; several landmark cases have been determined by the United States Supreme Court.
