High intensity proton beams in a multi-cycled SPS

The SPS ran for 247 days during 1994; 64% of this was with high intensity proton beam for physics data taking in the Fixed Target mode of operation, 12% was for a lead run at the end of the year, with the remaining 24% spent in setting up and machine development. The SPS supplied LEP with 8 bunches of electrons and 8 bunches of positrons either in the 14.4 or 19.2 seconds interleaved cycling mode during the operation with protons or lead ions respectively. The new record peak intensity during the year was 3.9/spl times/10/sup 13/ protons per pulse at 450 GeV. A total of 11/spl times/10/sup 18/ proton were delivered to all targets with an overall average during physics of 2.5/spl times/10/sup 13/ protons per pulse at 450 GeV. Some 6/spl times/10/sup 18/ protons were delivered to both neutrino experiments.
