The documents starts out with a discussion of Accelerators Past and Present High Voltage Accelerator Laboratory the Accelerator Concept the Van De Graaff Principle the Cockcroft-Walton Accelerator the 3mV Van de Graaff 5.5MV Van de Graaff The Tandem Concept The Tandem van de Graaff Experimental Nuclear Physics and Special Facilities. Tasked in 1948 with developing an accelerator program to initially produce neutrons for research Oak Ridge scientists begin acquiring or building Van de Graaff accelerators the only known source of neutrons with precise energies. They later acquire a Cockcroft-Walton unit an early particle accelerator named for its inventors to test radiation effects at lower energies. Oak Ridge National Laboratory ORNL is an American multiprogram science and technology national laboratory sponsored by the U.S. Department of Energy DOE and administered managed and operated by UT-Battelle as a federally funded research and development center FFRDC under a contract with the DOE. Established in 1942 ORNL is the largest science and energy national laboratory in the Department of Energy system by size and by annual budget. ORNL is located in Oak Ridge Tennessee near Knoxville. ORNL's scientific programs focus on materials neutron science energy high-performance computing systems biology and national security. ORNL partners with the state of Tennessee universities and industries to solve challenges in energy advanced materials manufacturing security and physics. The laboratory has several of the world's top supercomputers; among these Summit is ranked by the TOP500 as the world's second-most powerful supercomputer. The lab also is a leading neutron-science and nuclear-energy research facility that includes the Spallation Neutron Source and High Flux Isotope Reactor.
