History
The Road to the SRC: 1953 to 1968
In 1953 15 universities formed the Midwest Universities Research Association (MURA) to promote and design a high energy proton synchrotron, to be built in the Midwest. With the intent of constructing a large accelerator, MURA purchased a suitable area of land with an underlying flat limestone base near Stoughton, Wisconsin, about 10 miles from the Madison campus of the University of Wisconsin. A small electron storage ring, operating at 240 Mev, was designed as a test facility to study high currents, and construction of this ring started in 1965. However, in 1963 President Johnson had decided that the next large accelerator facility would not be built at the MURA site, but in Batavia, Illinois - this became Fermilab. In 1967 MURA dissolved with the storage ring incomplete and with no further funding.
In 1966 a subcommittee of the National Research Council, which had been investigating the properties of synchrotron radiation from the 240 MeV ring, recommended it be completed as a tool for spectroscopy. A successful proposal was made to the US Air Force Office of Scientific Research, and the ring was completed in 1968, administered by the University of Wisconsin. [2] For two decades Tantalus produced hundreds of experiments and was a testing ground for many of the synchrotron techniques used today. Its administrative home, the University of Wisconsin Synchrotron Radiation Center, was located in a
compound. , a fra [3]
Tantalus: 1968-1985
With the new Aladdin storage ring operating, Tantalus was officially decommissioned in 1987, although it was run for six weeks in the summer of 1988 for experiments in atomic and molecular fluorescence. The storage ring was disassembled in 1995, and half the ring, the RF cavity and one of the original beamlines are now in storage at the Smithsonian Institution.[2]
Aladdin: 1985
Funding for the new ring was obtained from the NSF, the State of Wisconsin, and the Wisconsin Alumni Research Foundation (WARF). The final design was a four straight section 1 GeV ring, of 89 m circumference, and construction of some componenets started 1978. A new 32,000 sq ft building to house the facility started construction in April 1979. The initial target date for first stored beam was October 1980. [7]
Recent funding difficulties
In 2011 a generally pro-science Federal budget for 2012 included the end of NSF funding for SRC. "Our last peer review said it would be a terrible mistake if we were closed," said Director Joseph Bisognano. But NSF had to trim its instrument and facilities budget by 15%, so it opted to cut funding for the centre.[8] The University gave SRC $2 million to keep the facility operating until June 2013, while new funding was sought. Bisognano stated the the biggest cutbacks were in education, outreach and support for outide users. By January 2012 the facility had lost around a third of its staff, from retirements and layoffs.

Notable Science
G. J. Lapeyre award
In 1973 the vault that held Tantalus was being enlarged, and during a facility picnic a rainstorm hit and caused the vault to start to flood. Jerry Lapeyre of Montana State University used the lab's tractor to build earthworks to divert the water. His efforts led then-director Rowe to create the annual G. J. Lapeyre award to be awarded to “one who met and overcame the greatest obstacle in the pursuit of their research”. The trophy has an octagonal base representing Tantalus, with a beer can from the lab picnic which preceded the flood, topped by a concrete “raindrop”.[10]
