Zero Gradient Synchrotron
The Zero Gradient Synchrotron, was a weak focusing 12.5 GeV proton accelerator that operated at the Argonne National Laboratory in Illinois from 1964 to 1979.
It enabled pioneering experiments in particle physics, in the areas of
- quark model tests;
- neutrino physics ;
- spin physics of hadrons ; and
- Kaon decays.
The hardware and building of the ZGS were ultimately inherited by a spallation neutron source program, the Intense Pulsed Neutron Source.
