The Official Story

LAWRENCE LIVERMORE NATIONAL LABORATORY (LLNL)

Lawrence Livermore National Laboratory (LLNL) is a federally funded research and development center in Livermore, California, United States. Originally established in 1952, the laboratory now is sponsored by the United States Department of Energy and administered by Lawrence Livermore National Security, LLC.

The lab was originally established as the University of California Radiation Laboratory, Livermore Branch in 1952 in response to the detonation of the Soviet Union’s first atomic bomb during the Cold War. It later became autonomous in 1971 and was designated a national laboratory in 1981.

A federally funded research and development center, Lawrence Livermore Lab is primarily funded by the U.S. Department of Energy and it is managed privately and operated by Lawrence Livermore National Security, LLC (a partnership of the University of California, Bechtel, BWX Technologies, AECOM, and Battelle Memorial Institute in affiliation with the Texas A&M University System). In 2012, the laboratory had the synthetic chemical element livermorium (element 116) named after it.

The Livermore facility was co-founded by Edward Teller and Ernest Lawrence, then director of the Radiation Laboratory at Berkeley.

PROJECT EXCALIBUR
(Strategic Defense Initiative)

Project Excalibur was a Lawrence Livermore National Laboratory (LLNL) Cold War–era research program to develop an X-ray laser system as a ballistic missile defense (BMD) for the United States. The concept involved packing large numbers of expendable X-ray lasers around a nuclear device, which would orbit in space. During an attack, the device would be detonated, with the X-rays released focused by each laser to destroy multiple incoming target missiles. Because the system would be deployed above the Earth’s atmosphere, the X-rays could reach missiles thousands of kilometers away, providing protection over a wide area.

Anti-ballistic missile (ABM) systems of the time only attacked the enemy nuclear warheads after they were released by ICBMs. A single ICBM could carry as many as a dozen warheads, so dozens of defense missiles were required per attacking missile. A single Excalibur device contained up to fifty lasers and could potentially destroy a corresponding number of missiles, with all of the warheads still on board. A single Excalibur could thus destroy dozens of ICBMs and hundreds of warheads for the cost of a single nuclear bomb, dramatically reversing the cost- exchange ratio that had previously doomed ABM systems.

The basic concept behind Excalibur was conceived in the 1970s by George Chapline Jr. and further developed by Peter L. Hagelstein, both part of Edward Teller’s “O-Group” in LLNL. After a successful test in 1980, in 1981 Teller and Lowell Wood began talks with US president Ronald Reagan about the concept. These talks, combined with strong support from The Heritage Foundation, helped Reagan ultimately to announce the Strategic Defense Initiative (SDI) in 1983. Further underground nuclear tests through the early 1980s suggested progress was being made, and this influenced the 1986 Reykjavík Summit, where Reagan refused to give up the possibility of proof-testing SDI technology with nuclear testing in space.

Researchers at Livermore and Los Alamos began to raise concerns about the test results. Teller and Wood continued to state the program was proceeding well, even after a critical test in 1985 demonstrated it was not working as expected. This led to significant criticism within the US weapons laboratories. In 1987, the infighting became public, leading to an investigation on whether LLNL had misled the government about the Excalibur concept. In a 60 Minutes interview in 1988, Teller attempted to walk out rather than answer questions about the lab’s treatment of a fellow worker who questioned the results. Further tests revealed additional problems, and in 1988 the budget was cut dramatically. The project officially continued until 1992 when its last planned test, Greenwater of Operation Julin, was cancelled.

First attempts at Livermore

George Chapline had been studying the X-ray laser concept through the 1970s. Chapline was a member of Teller’s speculative-project “O- Group” and began to discuss the concept with fellow O-Group member Lowell Wood, Teller’s protégé. The two collaborated on a major review of the X-ray laser field in 1975. They suggested such a device would be a powerful tool in materials science, for making holograms of viruses where a conventional laser’s longer wavelength did not provide the required optical resolution, and as a sort of flashbulb for taking images of the nuclear fusion process in their inertial confinement fusion devices. This review contained the calculations that demonstrated both the rapid reaction times needed in such a device and the extremely high energies required for pumping.

Chapline attended a meeting where Sobel’man’s work on X-ray lasers was presented. He had learned of the unique underground nuclear tests made on behalf of the Defense Nuclear Agency (DNA), where the burst of X-rays produced by the nuclear reactions were allowed to travel down a long tunnel while the blast itself was cut off by large doors that slammed shut as the explosion approached. These tests were used to investigate the effects of X-rays from exoatmospheric nuclear explosions on reentry vehicles. He realized this was a perfect way to pump an X-ray laser.

After a few weeks of work, he came up with a testable concept. At this time the DNA was making plans for another of its X-ray effects tests, and Chapline’s device could easily be tested in the same “shot”. The test shot, Diablo Hawk, was carried out on 13 September 1978 as part of the Operation Cresset series. However, the instrumentation on Chapline’s device failed, and there was no way to know if the system had worked.

Congress directed that $10 million be given to both Lawrence Livermore National Laboratory (LLNL) and Los Alamos National Laboratory (LANL) for weapons tests on entirely new concepts. Chapline was given the go-ahead to plan for a new test dedicated to the X-ray laser concept. In the DNA tests, the reentry vehicle had to be retrieved for study after the test, which demanded the complex system of protective doors and other techniques that made these tests very expensive. For the X-ray laser test, all of this could be ignored, as the laser was designed to be destroyed in the explosion. This allowed the laser to be placed at the top of the vertical access shaft, which greatly lowered the cost of the test from the typical $40 million needed in a DNA shot. Given the schedule at the Nevada Test Site, their test would have to wait until 1980.
