Its planned ring circumference was 87.1 kilometres (54.1 mi) with an energy of 20 TeV per beam of protons. The project's director was Roy Schwitters, a physicist at the University of Texas at Austin and Harvard University. Dr. Louis Ianniello served as Associate Director.[2] The project was cancelled in 1993 due to budget problems.

Development
The system was first envisioned in the December 1983 National Reference Designs Study, which examined the technical and economic feasibility of a machine with the design capacity of 20 TeV per beam. After an extensive Department of Energy review during the mid-1980s, a site selection process began in 1987. The project was awarded to Texas in November 1988 and major construction began in 1991. Seventeen shafts were sunk and 23.5 km (14.6 mi) of tunnel were bored by late 1993.[3]
Cancellation
During the design and the first construction stage, a heated debate ensued about the high cost of the project. In 1987, Congress was told the project could be completed for $4.4 billion, and it gained the enthusiastic support of Speaker Jim Wright of nearby Fort Worth.[4][dubious ] By 1993, the cost projection exceeded $12 billion. A recurring argument was the contrast with NASA's contribution to the International Space Station (ISS), a similar dollar amount.[citation needed] Critics of the project argued that the US could not afford both of them. Early in 1993 a group supported by funds from project contractors organized a public relations campaign to lobby Congress directly,[5] but in June, the non-profit Project on Government Oversight released a draft audit report by the Department of Energy's Inspector General heavily criticizing the Super Collider for its high costs and poor management by officials in charge of it.[6][7]
Congress officially canceled the project October 21, 1993.[8] Many factors contributed to the cancellation: rising cost estimates; poor management by physicists and Department of Energy officials; the end of the need to prove the supremacy of American science with the collapse of the Soviet Union; belief that many smaller scientific experiments of equal merit could be funded for the same cost; Congress's desire to generally reduce spending; the reluctance of Texas Governor Ann Richards;[9] and President Bill Clinton's initial lack of support for a project begun during the administrations of Richards's predecessor, Bill Clements, and Clinton's predecessors, Ronald Reagan and George H. W. Bush. However, in 1993, Clinton tried to prevent the cancellation by asking Congress to continue "to support this important and challenging effort" through completion because "abandoning the SSC at this point would signal that the United States is compromising its position of leadership in basic science".[10]
The closing of the SSC had adverse consequences for the southern part of the Dallas–Fort Worth Metroplex, and resulted in a mild recession, most evident in those parts of Dallas which lay south of the Trinity River.[11] When the project was canceled, 22.5 km (14.0 mi) of tunnel and 17 shafts to the surface were already dug, and nearly two billion dollars had already been spent on the massive facility.[12]
Comparison to the Large Hadron Collider
The SSC's planned collision energy of 40 TeV was almost triple the 14 TeV of its European counterpart, the Large Hadron Collider (LHC) at CERN in Geneva.
The SSC cost was due largely to the massive civil engineering project of digging a huge tunnel underground. The LHC in contrast took over the pre-existing engineering infrastructure and 27 km long underground cavern of the Large Electron-Positron Collider, and used innovative magnet designs to bend the higher energy particles into the available tunnel. [13]. The LHC eventually cost the equivalent of about 5 billion US dollars to build.
Current status of site
After the project was canceled, the main site was deeded to Ellis County, Texas, and the county tried numerous times to sell the property. The property was finally sold in August 2006 to an investment group led by the late J.B. Hunt.[14] Collider Data Center has contracted with GVA Cawley to market the site as a tier III or tier IV data center.[15] As of October 2010, the site is abandoned and run-down.
