Thomas W. L. "Tom" Sanford (born around 1945) is an American plasmaphysicist who developed a multi-wire array for use in a pulsedZ-pinch plasma system which resulted in a breakthrough forinertial confinement fusion (ICF) research.[1][2] In 2005, he was awarded theHannes Alfvén Prize with Malcolm Haines andValentin Smirnov for his contributions to the field.[3]

Life and career

[edit]

Sanford studied mathematics and physics at theUniversity of Washington and obtained abachelor's degreemagna cum laude in 1965. He then went on toColumbia University, where he completed hismaster's degree in physics in 1967 and received his doctorate fromLeon M. Lederman in 1973.[4] Upon his graduation, he worked at theRutherford Appleton Laboratory (with T. G. Walker), atCERN and at theBrookhaven National Laboratory (withSamuel C. C. Ting).[2] In 1982, he was a member ofSandia National Laboratories and was involved in the development of the HERMES III (High Energy Radiation Megavolt Electron Source)electron accelerator, which was used to generateX-rays andgamma rays to simulate the effects of nuclear explosions.[5] In 1991, he became a Distinguished Member of the laboratory.

Scientific contributions

[edit]

Sanford further developed theZ-pinch with wire arrangements, which had previously been successfully tested in Russia byValentin Smirnov, via the Saturn experiment to theZ-machine.[6][7] It was the strongest X-ray source in the mid-2000s (2megajoules in 6nanoseconds with 200terawatts of power),[8] which also generated record temperatures of 2 to 3 billion Kelvin for a short time.[9] Two cylindrical shells of wire assemblies, through which a high current (20 megaamps) is sent, implode onto a central target, where high-intensity X-rays are generated for inertial fusion experiments or other studies.[10][11] This was studied with the dynamic hohlraum X-ray source.[12][13]

Honors and awards

[edit]

Sanford is a fellow of theAmerican Physical Society since 2000.[14]
