The Superconducting Super Collider (SSC) was a ring particle accelerator which was planned to be built in the area around Waxahachie, Texas. It was planned to have a ring circumference of 87 km (54 miles) and an energy of 20 TeV per beam, potentially enough energy to create a Higgs boson, a particle predicted by the Standard Model, but not yet detected. The project's director was Roy Schwitters, a physicist at the University of Texas at Austin and Harvard University.

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 miles) of tunnel were bored by late 1993.

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, but by 1993 the cost projection exceeded $12 billion. An especially recurrent argument was the contrast with NASA's contribution to the International Space Station (ISS), which was of similar amount. Critics of the project argued that the US could not afford both of them.

The project was canceled by Congress in 1993. Many factors contributed to the shutdown of the project, although different parties disagree on which contributed the most. They include rising cost estimates, mismanagement 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, and the reluctance of Texas Governor Ann Richards ^[1] and President Bill Clinton, both Democrats, to support a project begun during the administrations of Richards's Republican predecessor, Bill Clements, and Clinton's Republican predecessors, Ronald Reagan and George H. W. Bush. However, in 1993, Clinton attempted to prevent the cancellation by requesting that Congress 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..." ^[2]

The closing of the SSC held drastic ramifications for the southern part of the Dallas/Fort Worth Metroplex, and resulted in a mild recession made most evident in those parts of Dallas which lay south of the Trinity River.^[3] At the time the project was cancelled, 22.5 km (14 miles) of tunnel and 17 shafts to the surface were already dug and nearly 2 billion dollars had already been spent on the massive facility.^[4]

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 of 2006 to^[5] an investment group led by the late J.B. Hunt. Collider Data Center has contracted with GVA Cawley to market the site as a Tier III or Tier IV Data Center^[6]. The site is currently unoccupied.

While owned by Ellis County, Texas, the site was used for several different purposes, including storage for the county and the production of Jean-Claude Van Damme's 1999 movie "Universal Soldier: The Return".

• John Cramer wrote the novel Einstein's Bridge which presents an alternate history in which the SSC was completed successfully. Dramatic events then require time travel and the alteration of history to save the earth and bring us to where we are today.
• A Hole in Texas by Herman Wouk is loosely based on the history of the SSC project.
• In and episode of The West Wing, Sam Seaborn battles a US Senator who has put an anonymous hold on the project, at the request of Sam's physics professor.
