Isotope Separator On-Line Device

Target entity: Isotope Separator On-Line Device
Context triple: [ISOLDE, fullName, Isotope Separator On-Line Device]

• A. Oppenheimer–Phillips process
  The Oppenheimer–Phillips process is a nuclear reaction mechanism in which a deuteron interacting with a target nucleus effectively transfers its neutron while the proton is repelled, enabling certain reactions to occur at lower energies than would otherwise be required.
• B. Antiproton Decelerator
  The Antiproton Decelerator is a specialized CERN facility that slows down antiprotons to low energies for precision experiments in antimatter physics.
• C. Chicago Pile-1
  Chicago Pile-1 was the world’s first artificial nuclear reactor, achieving the first controlled, self-sustaining nuclear chain reaction in 1942 under the leadership of Enrico Fermi.
• D. Proton Synchrotron
  The Proton Synchrotron is a historic circular particle accelerator at CERN that has played a key role in high-energy physics research and in feeding beams to larger colliders.
• E. K-West Reactor
  K-West Reactor is one of the plutonium production reactors at the Hanford Site in Washington State, historically used to support the U.S. nuclear weapons program.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
