Abstract

TRIUMF is considering the construction of a "kaon factory" post-accelerator to take the present 100 ~ proton beam (6 x 10¹⁴ p/s) f rom 500 MeV to energies in the tens of GeV. This would provide beams of kaons, antiprotons, neutrinos, etc., 100-1000 times more intense - or alternatively cl eaner - than those available at present. Such beams would open up new fields in both nuclear and particle physics in the same way that the pion factories LAMPF, SIN and TRIUMF have done at lower energies; in particular the enhanced ability to study rare processes could throw light on mass regions far beyond those accessible with any presently conceivable super-high energy accelerator. Since it is understood that there are no definite plans to use the dipole magnets from the Intersecting Storage Rings at CERN af t er closure of the ISR in 1984, a study has been undertaken to assess the feasibility of incorporating them in a TRIUMF kaon factory. If these magnets were available at nominal cost, then for the same total funds it should be possible to build a kaon factory of considerably higher energy and physics capability. Out of various options the one selected as most suitable in terms of its physics capability, site requirements and cost would use one ring of magnets for a 30 GeV 50 ~ synchrotron and the other for a 30 GeV dc stretcher ring.. The magnets would be reconfigured in a regular 48 cell FFODDO lattice, apart from 4 straight sections. The two rings would be mounted one above the other in the same tunnel, along with a dc accumulator ring at the injection energy. This arrangement would have the advantage of providing both low and high duty factor beams from the outset. The synchrotron magnets would operate with a triangular waveform at 0.5 Hz, using flywheel/motor generator energy storage. In the longer term a 60 GeV superferric or 120 GeV superconducting ring could be added in the tunnel.
