The Supercollider That Never Was

Wow, I had no idea that this was even in the works here in the United States. But I’m not surprised to find that once again the U.S., as a result of politics, failed to come through on what could have been a remarkable achievement, as we continue to fall further and further behind other countries in technology. Oh well… The bottom line is there is too much BS in the U.S. Someday we’ll come to that realization, although by then it may be too late. TGO

If all had gone according to plan, the gargantuan U.S. high-energy physics project would have already found the Higgs particle, having solidly won the competition with its European competitor. Peter Higgs, in fact, might have collected his physics Nobel a few years earlier.

The Superconducting Super Collider (SSC) that would have graced the rolling prairies of Texas would have boasted energy 20 times larger than any accelerator ever constructed and might have been revealing whatever surprises that lay beyond the Higgs, allowing the U.S. to retain dominance in high-energy physics. Except the story didn’t play out according to script. Twenty years ago, on October 21, 1993, Congress officially killed the project, leaving behind more than vacant tunnel in the Texas earth.

Since then, the glory of particle physics has moved to Europe. Last year the Large Hadron Collider (LHC) at the CERN laboratory in Geneva, Switzerland, discovered the Higgs, the biggest event in physics in a generation, and, adding insult to injury, announced it on a U.S. national holiday: the Fourth of July.

What went wrong with the SSC, in a nation then usually admired for its can-do attitude? What lessons were learned to apply to future efforts? And what has been the impact on U.S. physics since the spotlight moved to Europe?

What happened?

Although no one reason explains the cancellation, a few key aspects of the project stand out. The inability to secure any foreign sources of funding was pivotal, especially as the project’s cost increased by a factor of three from initial estimates amid a national recession and political insistence on controlling government spending. The project’s scale was 20 times bigger than anything physicists had ever managed before, and cultural differences between the scientific side of the accelerator’s management and the military-industrial culture imposed by the U.S. Department of Energy (DoE) led to conflicts, seemingly endless audits and an overall lack of trust.

An accelerator that would collide high-energy protons, the SSC’s ring was to be 87.1 kilometers in circumference, circling the small town of Waxahachie, Tex., 48 kilometers south of Dallas. At 20 tera-electron volts (TeV, or trillion electron volts) per proton—close to the regime of ultrahigh-energy cosmic rays—it was to have 20 times the collision energy of any existing or planned machine; it would have had five times the energy of even today’s LHC collisions. That design had only one tenth the beam luminosity of the LHC, but because of its higher energy, it would have produced about half the Higgs events seen at CERN, says John Gunion of the University of California, Davis, enough to have found the Higgs and with the higher energy necessary to detect what, if anything, lies past the Higgs energy, such as supersymmetric or dark matter constituents.

When canceled, about 20 percent of the SSC was complete—specifically, two dozen kilometers of  tunnel had been drilled with 17 access shafts, and 18,600 square meters of buildings erected. Over $2 billion had already been spent, mostly by the DoE, but also $400 million by the state of Texas.

At its end the project was already employing 2,000 people at the site or in Dallas, about 200 of whom were scientists, plus a contingent of Russian physicists employed after the end of the Cold War. Another 13,000 jobs linked to the project never materialized. About half the SSC scientists left the field of physics, according to a 1994 survey by Science magazine, some to become analysts in the financial industry. Many took a loss on homes sold in a sudden buyer’s market.

Overbudget, the SSC had been on shaky ground for at least a year before the plug was pulled. Design began in 1983, and then Pres. Ronald Reagan’s science advisor told the design committee to be “bold and greedy.” Reagan approved the project in 1987, encouraging physicists to “throw deep.” (Early names for the collider included the “Ronald Reagan Accelerator,” the “Desertron” (because it was so large it could only be built in the U.S. Southwest), and even the “Gippertron.”)

Originally estimated to cost $4.4 billion, the U.S. House of Representatives voted to kill the project in the summer of 1992, when costs had risen to $8.25 billion, but it was saved by the Senate, although a $100-million cut below requested funds put the project further behind schedule, increasing its costs even more. By the fall of 1993 the estimated cost had risen to a minimum of $11 billion (equivalent to $18 billion today), in part because administrative overhead proved larger than anticipated, and refined calculations of expected beam losses lead to a magnet redesign. (There were to be about 10,000 of them in the ring.) The latter’s increased cost, about $2 billion, could have been avoided by accepting a smaller ring and its resulting lower energy, but that idea was rejected by upper scientific and academic management.

But not all of the project’s costs were included in the initial estimates, according to a DoE report completed four years after the ax came down. About $500 million for detectors, $400 million for operations needed before the lab was finished, $60 million for land purchases and $118 million for DoE project management were excluded from cost estimates. Crucial to projects of such a size, a project cost and scheduling system was never fully implemented, concealing substantial cost overruns, according to the report.

“The Department of Energy was looking for a new level of project management when they embarked on supercollider,” says Michael Riordan, a science historian who is a lead author of the forthcoming Tunnel Visions: The Rise and Fall of the Superconducting Super Collider. “They did not trust they could get that from the high-energy physics community, and I think they were partially correct in that.”

Foreign funds that never came

It was always expected that $2.6 billion in funds from foreign governments and from the accelerator’s home state would supplement DoE dollars. Although Texas did promise $900 million, and deliver $400 million before the project’s cancellation, none of the seven countries that DoE officials looked to for the rest came up with money, except for a $50 million pledge from India.

From the beginning officials seemed conflicted about the project’s goals. Riordan wrote that at a 1987 press conference, the day after Reagan’s go-ahead, “Secretary of Energy John Herrington told reporters that the SSC would be ‘an American project [with] American leadership,’ but at the same time the DoE also intended ‘to seek maximum cost-sharing funding from other countries.’” Such nationalistic rhetoric tamped enthusiasm from Canada, Europe, and Japan when DoE went looking for financial pledges.

In Europe maintaining success at the CERN laboratory was the priority, after its 1983 discoveries of the W and Z bosons responsible for weak interactions, and it would have made little sense to collaborate on a machine larger than the Large Hadron Collider they were then considering. Despite the Soviet Union’s dissolution in 1991 Russia’s focus and funds went elsewhere; the end of the Cold War also repurposed attitudes in the U.S., reducing emphasis on big, technological science projects that displayed national might. The SSC also competed for funding with the development of the International Space Station, including the Johnson Space Center and other NASA operations in Texas.

That left Japan as a major target for foreign funding. Delegations began visiting Japan as early as 1984, but tensions over Tokyo’s inroads into the U.S. automobile market often got in the way, as did U.S. requests that Japan establish quotas for importation of U.S. auto parts. By 1991 Pres. George H. W. Bush’s popularity was falling, and the Japanese were not convinced of U.S. commitment to the SSC. The accelerator was to feature prominently in Japan–U.S. observances of the 50th anniversary of the December 1941 attack on Pearl Harbor, but Bush’s trip to Japan was delayed as trade tensions mounted. With the tenor of the relationship in flux, high-level talks on the SSC came to nothing, and Bush’s visit to Japan in early 1992, where the Japanese expected the U.S. president to directly ask Prime Minister Kiichi Miyazawa for SSC funding, ended with Bush’s unfortunate and embarrassing regurgitation on Miyazawa. Noting that Bush’s reelection looked increasingly unlikely, Japan postponed a decision on the SSC. And despite expressing support for it as a presidential candidate, Bill Clinton and his administration never gave much support to the project.

What should the U.S. have done differently? Burton Richter, the Nobel laureate who was then director of the Stanford Linear Accelerator Center (now known as the SLAC National Accelerator Laboratory) in California, says “it was a very bad mistake to seek funding only after the design parameters of the project were determined.”

There was also infighting among subfields of U.S. physics, as condensed matter physicists were especially concerned that the SSC would drain funding from other specialties. Many physicists spent at least a year grieving and venting their disappointment and anger in public, especially in Physics Today, the U.S. magazine devoted to covering the field. When the SSC was finally canceled, the late Rustum Roy, professor of materials sciences at The Pennsylvania State University, expressed his joy to the New York Times. “This comeuppance for high-energy physics was long overdue.” Roy said. “There is an acute oversupply of scientists in the United States,” which he and others said was the educational system’s responsibility to fix.

Richter, now director emeritus at SLAC, thinks the bitterness between subfields of physics has faded, and that scientists learned a valuable lesson: “Once a project is approved, shut up.”

A lack of will

It was not just physics that lost out when the SSC was canceled. There had been tremendous support from the state of Texas and from the local community, and their enthusiasm came to naught. Some lost land rights that went to construction of the tunnel, and dozens of homes were moved for building construction, but there was little of the bitterness that might be expected today. “There was a great feeling of support from the local people,” says Roy Schwitters, professor of physics at The University of Texas at Austin who was the SSC’s director for its last five (and most significant) years, “even from those who lost their homes. They liked the idea that the country did super, far-out things,” he added. Local schools welcomed the collider, and lab scientists set up cosmic-ray monitors in classrooms to teach the basics of particle science (with plans to later demonstrate that no harmful radiation was coming from the accelerator). “I think it was a tragedy for the country, and certainly for high-energy physics,” Schwitters says. “It’s almost removed the possibility—the vision—that you can build really new major projects when the scientific community gets behind and supports them.”

Some see an even larger picture in the SSC’s demise. “You can blame lots of people,” says Nicholas Samios, former director of the Brookhaven National Laboratory, “but it was clearly a lack of will. We always got things done. It turned a getting-things-done society into a conservative, play-it-safe, no-risk society,” Samios laments. “We’re not made of the right stuff anymore.”

Today the SSC buildings are occupied by Waxahachie chemical manufacturer Magnablend. Access shafts have been filled in, and what tunnel remains collects rainwater. Amidst endless budget problems, Congress flits with large science projects like the James Webb Space Telescope, canceling and then reversing as costs and completion dates lengthen—scenarios eerily familiar to the SSC’s tragic path. The European-based CERN was the major focus of the 2013 physics Nobel to Peter Higgs and François Englert, and it is Japan, not the U.S., talking of hosting an International Linear Collider.

Despite fears at the time, the SSC did not herald the end of U.S. particle physics, by any means. (In 1993 the Division of Physics of Beams made up 3.4 percent of the American Physical Society’s membership; this year it is 2.3 percent, a decline of 361 members.) Physics faces a host of new questions, such as the nature of dark energy, the identity of dark matter and the subtle properties of neutrinos, not all of which can be answered by ever more powerful accelerators. But others can, such as the exact properties of the Higgs boson and the ever-tantalizing possibility of supersymmetry. The current design of the LHC places a hard energy limit of 16 TeV (8 TeV in each beam), and no physics above that threshold can appear, no matter how high its beam intensities. The SSC would have punched at a higher weight.

Yet Riordan believes the U.S. made a mistake by reaching for such a high energy at the SSC, when a lower energy might have discovered the Higgs particle, as recent experience has confirmed. “The high-energy physics community insisted on the largest possible machine, so large it didn’t have the skills to manage it,” he says. “American physicists wanted to leapfrog the Europeans and reestablish their leadership in high-energy physics—which was a political reason, not a physics reason.”

Many believe accelerator physics still has an important role to play, such as with a linear collider that will by necessity be a worldwide effort. “I do not believe that we can make significant progress without also pushing back the frontier of high energy,” Nobel laureate Steven Weinberg wrote in an essay titled “The Crisis of Big Science” in The New York Review of Books last year. “So in the next decade we may see the search for the laws of nature slow to a halt, not to be resumed again in our lifetimes.”

The SSC was an epic project that ended in failure. The U.S. has yet to stride again its own once prominent footsteps; but perhaps worse, it no longer dares to dream in color. Whatever the future for high-energy physics the U.S. and the world, the hulking beast that would have been the Superconducting Super Collider will not soon be forgotten.
