CERN Courier, April 1982 111 Ten years ago, on 1 March 1972, Fermilab Director Robert R. Wilson toasted the attainment of 200 GeV, the nominal Main Ring design energy. In 1976 this was boosted to 500 GeV, and now the Laboratory looks towards 1 TeV (1000 GeV). (Photo Fermilab) on the way to completion of the Fermilab Energy Saver/Doubler has been achieved with the oper­ ation of a 2400 foot-long supercon­ ducting magnet string comprising three-quarters of a sector of the total ring. Tests of the first sector of the Saver have been under way since mid-January. Nearly half a mile of superconducting bending magnets in the main ring tunnel have been cooled and powered to 2200 A which is equivalent to an energy of approximately 500 GeV. The string includes roughly one-eighth of the Saver magnets. Three separate cryogenic loops are in operation from the A 1, A2, and A3 service buildings. The total system is operating in conjunction with three satellite refrigerators and the Central Helium Liquefier. Twenty-four half cells are in the string with each half cell consisting of four dipoles, one quadrupole While Brookhaven's operating Tevatron II approval and a spool piece which contains funds have been increased, allow­ the correction elements. ing for an extensive superconduct­ The Tevatron II project at Fermilab Many tests are under way as ing magnet research and develop­ to convert the Energy Saver to full the current through the system is ment programme, initially no funds 1000 GeV experimental operation raised by stages.

The system is handled from the existing central control room in parallel with normal opera­ tion. SLC Workshop Some 150 physicists met at SLAC recently to discuss reports on the experimental prospects at the SLAC Linear Collider (SLC). This meeting concluded the first phase of study for the SLC physics pro­ gramme. Most of the agenda was devoted to the presentation of the reports of the eight specialist subgroups set up last year (see June 1981 issue, page 199). These reports are being published as proceed­ ings. On view was new hardware de­ veloped for SLC, including a new beam position monitor to handle the intense SLC bunches.
