  Lawrence and His Laboratory: Chapter 6: Bumper Crop
Among the problematic features of the Bevatron's design was the size of the gap or aperture in which the magnets constituting the machine's backbone would confine the beam.
(The Bevatron actually built has four curved and four straight sections.) One straight section served to admit the proton beam from a small linear accelerator, which took its feed from a Cockcroft-Walton machine; in the final design, the particles gained 500 keV in the first stage of acceleration and another 9.5 MeV in the second.
Perhaps the farthest reaching of the discoveries made with the Bevatron were the so-called "resonances" or energies at which fleeting combinations of particles occur.

 BERKELEY / Radioactivity fears have some calling for Bevatron preservation / Lawrence lab wants to demolish facility to ...
The laboratory has proposed spending as much as $85 million to raze the 8,100-square foot Bevatron and the building that houses it to make room for future projects on their 2.25-acre hillside perch overlooking the campus and San Francisco Bay.
The Bevatron, a synchrotron accelerator used in particle and nuclear physics research, was state of the art when it began operation in 1954.
Edward Lofgren, who worked at the Bevatron in various capacities throughout its life and supervised its operation for much of that time, said he did not think preserving the accelerator was a worthy idea given the need for the space and the costs involved.

In 1954, Lawrence commissioned the Bevatron accelerator to reach energies of several billion electron-volts - then designated as BeV (now universally known as GeV) - to be built at his Radiation Laboratory in Berkeley.
As the Bevatron's proton beam struck a target in the form of a copper block, fragments of nuclear collisions would emerge in all directions.
On 21 September, a week after operating crews had revived the Bevatron, Lofgren's group was to begin a four-day run, but instead it ceded its time to Segrè and Chamberlain.

The Bevatron was named for its ability to charge atomic particles to more than six billion electron volts, or BeVs.
As with the lingering tritium debate, much of the Bevatron dispute comes down to a profound lack of trust between the two sides and a seemingly irreconcilable difference between the environmentalist and scientific worldviews.
While the Bevatron may have sat idle in the Berkeley Hills for a nearly a decade, the old accelerator has managed to reenergize a local battle that won't be so easily disposed of.

Famous for the four Nobel prizes awarded for research conducted there, the Bevatron is a winding maze of overhead circular metal pipes and machinery contained in a unique circular building with a conical roof.
LBNL did apply for and was granted eligibility status for the Bevatron in the National Registry of Historic Places.
Another reason for not demolishing the Bevatron is that by leaving it intact, the significant quantities of toxic and radioactive substances locked up deeply in the walls and shielding blocks would be able to remain safely sealed with some able to decay in place, which is what is recommended by leading environmental organizations.

The lab plans to dissemble and transport the Bevatron's apparatus and concrete structure to prospective, safe landfills in Utah and Nevada because the lab no longer uses the accelerator for research.
The Bevatron, constructed in 1954, closed down in 1993 because the lab stopped receiving funding for it from the U.S. Department of Energy.
Members of the committee suggest that the Bevatron become a historical building because it is the birthplace of four Nobel prizes and the central site where anti-protons, highly energized particles, were created.

At a press conference called to announce the acceleration of heavy ions in the Bevatron last month, Lawrence Berkeley Laboratory scientists meet local newsmen.
The press conference marked the fact that the Bevatron had successfully accelerated electrically charged ions (stripped nuclei) of the element nitrogen to 36 billion electron volts.
This is the first time that heavy atomic nuclei have been accelerated to energies in the multi-BeV range.

The commission conducted an initial hearing on LA Wood’s proposal to landmark the Bevatron Building at the Lawrence Berkeley National Laboratory (LBNL).
Lab officials—including Ben Feinberg, the last head of Bevatron operations— and a graduate student argued against declaring the building a landmark, saying that the best monument to the history of the site would be construction of new labs equipped with the latest hardware to conduct more ground-breaking research.
Completed in 1953, the Bevatron was in operation until Feb. 21, 1993, by which time larger and more powerful particle accelerators had become the source of most new discoveries.

 Volta
The energy of moving charged particles produced by modern atom-smashing machines is measured in electron-volts.
A billion electron-volts is abbreviated "bev," and when we speak of the particular atom-smasher called the bevatron, the "v" in the name stands for Volta.
Of Volta's numerous inventions, his two most influential are: the electrophorous and the Voltaic pile.

The Bevatron is a synchrotron accelerator that began operations in 1954, was last operated in 1993, and is now abandoned in place within Building 51, a 126,500-square-foot steel frame structure.
The accelerator is about 180 feet in diameter and made significant contributions in the fields of particle and nuclear physics during its 40 years of operation.
The concrete shielding blocks that surround the Bevatron would be removed, the Bevatron apparatus would be disassembled, Building 51 and the shallow foundation underneath the building demolished, and the resulting debris and other materials removed.

 Synchrotron - Wikipedia, the free encyclopedia
Modern industrial-scale synchrotrons can be very large (here, Soleil near Paris)
One of the early large synchrotrons, now retired, is the Bevatron, constructed in 1950 at the Lawrence Berkeley Laboratory.
The name of this proton accelerator comes from its power, in the range of 6.3 GeV (then called BeV for billion electron volts; the name predates the adoption of the SI prefix giga).

The Lawrence Berkeley Lab held a scoping meeting for the public on Thursday, March 31, 2005, 6:30 p.m.-8:30 p.m., at North Berkeley Senior Center to present its plan to demolish the Bevatron (a massive particle accelerator) and Building 51.
An alternative to demolition and removal would be to allow the Bevatron and its contamination to remain onsite in relative containment.
This would also preserve the historic aspects of the Bevatron, as it is eligible for listing in the National Register of Historic Places for the research in particle physics, which resulted in four Nobel prizes.
