Accelerator field development at Novosibirsk (history, status, prospects)

The path to high-energy electron-positron colliders: from Wideroe's betatron to Touschek's AdA and to LEP

“…But, at this time, the concept of stacking beams of particles and making them collide head-on had begun to be investigated [8,9]. Projects for electron-electron storage rings were started in the US [10], as well as in the Soviet Union under the direction of Gersh Budker, first in Moskow and then in the new laboratory of Novosibirsk in Siberia [11].…”

“…As Touschek later wrote: "The challenge of course consist [ed] in having the first machine in which particles which do not naturally live in the world which surrounds us can be kept and conserved." 11 A few weeks after the CERN conference, Wolfgang K.H. Panofsky, from Stanford University, was in Rome giving a seminar about the electron-electron rings being built in the USA, and the question of using electrons and positrons was raised again, by Bruno Touschek.…”

“…energy as being the highest energy to study pair production of all the elementary particles known to exists at the time, pions, kaons, including studies of the nucleon-antinucleon threshold around 2.0 GeV. In the Soviet Union [11,19] the construction of VEPP-2, a 2000 MeV electron-positron collider, was accelerated in earnest, in the USA, at Stanford, an e + e − ring with the highest energy of them all, the Stanford Positron Electron Accelerating Ring (SPEAR), with c.m. of 6.0 GeV, was approved with University funding, and built in a vacant lot owned by the University [20].…”
