  • 1960 Project Matterhorn staff, now numbering nearly 400, moves to C-Site, a large modern laboratory and office complex built to house the Model C Stellarator.
  • 1961 Melvin B. Gottlieb succeeds Lyman Spitzer, Jr. as head of Project Matterhorn. On February 1, Project Matterhorn is renamed the Princeton Plasma Physics Laboratory (PPPL). The change signified recognition of the fact that long-range physics research lay ahead.
  • 1962 Model C Stellarator begins operation in March following a 4-1/2-year design and construction effort. The largest of a series of stellarators, it is a test-bed for intense studies of plasma transport. With the coming of the Model C, the figure-8 stellarators of the 1950s surrendered their center-stage position.
  • 1964 PPPL's first program to use neutral-beam injection for plasma heating is proposed. During the next three decades, neutral-beam heating will play a key role in the progress toward the attainment of the plasma conditions required for the production of significant amounts of fusion power.
  • 1966 The Linear Multipole-1 (LM-1) begins operation. LM-1 experiments are the first to investigate the magnetic well concept. These experiments confirm theoretical hypotheses.
  • 1969 In July, it is decided to convert the Model C Stellarator to a tokamak. Model C ceases operation on December 20. Its conversion to the Symmetric Tokamak will take only four months.
