Two accelerators switch to nitrogen ions
DOI: 10.1063/1.3022468
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
