Scope and content
Twelve nations are members of the European Organization for Nuclear Research (CERN), a new organization set up under UNESCO sponsorship to aid the co-operation between separate research centers in the field of nuclear theory. The CERN program is concentrated on two big machines, a spectro-cyclotron and a proton-synchrotron, now under construction at the CERN laboratory site near Geneva.
The proton-synchrotron is designed to reach energy levels of 25 thousand million electron volts, or over; in this machine the protons will move inside a vacuum chamber along a circular path formed by an electro-magnet with a diameter of 200 meters and a weight of about 3500 tons; the protons will be accelerated to a speed approaching that of light.
This picture shows part of the 500 Kv. cascade or Cockroft-Walton generator which constitutes the first stage of the Alvarez-type linear accelerator of the proton-synchrotron.
