Two accelerators switch to nitrogen ions

DEC 01, 1971

Marian S. Rothenberg

Experiments with high‐energy nitrogen ions have now been done at two accelerators that were formerly devoted only to elementary‐particle physics. At the Princeton Particle Accelerator (PPA) a 3.9‐GeV nitrogen beam was achieved on 15 July, and the Bevatron at the Lawrence Berkeley Laboratory (LBL) produced its 36‐GeV beam on 17 August. Both laboratories can now produce beams of sufficient intensity (at least $10^{5}$ particles per sec) to carry out experiments, and the broad range of scientists eager to use the energetic heavy ions includes biologists, nuclear chemists, astrophysicists, solid‐state physicists and high‐energy physicists.
