The Zero Gradient Sychrotron (ZGS), was a weak focussing 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 (observation of neutrino interaction in its 12ft hydrogen bubble chamber for the first time in 1970); *spin physics of hadrons (utilizing a polarized accelerated proton beam in the GeV range for the first time); and *Kaon decays. The hardware and building of the ZGS were ultimately inherited by a spallation neutron source program, the Intense Pulsed Neutron Source (IPNS). ==References== *''Symposium on the 30th Anniversary of the ZGS Startup'', Malcolm Derrick (ed), ANL-HEP-CP-96-12, 1994. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Zero Gradient Synchrotron」の詳細全文を読む スポンサード リンク
