KAON Factory study : accelerator design report TRIUMF-KAON Project

Abstract

To produce the intense beams of kaons and other exotic sub-atomic particles desired at the KAON Factory the atoms in a solid target must be bombarded with high intensity beams of high energy protons (nuclei of the lightest atom, hydrogen). Experience at Brookhaven National Laboratory in the USA and at CERN (the European Centre for Nuclear Research) in Switzerland has shown that the protons should have a kinetic energy of at least 30 GeV (giga- or billion electron-volts). At this energy the protons are travelling at 99.95% of the speed of light and are about 30 times more massive than at rest. Their energy is raised to this level step by step in a series of particle accelerators (commonly known as atomsmashers). To produce 100 times more kaons than have been available at Brookhaven and CERN the KAON Factory must be capable of accelerating beam intensities of 100 microamperes (6 X 10¹⁴ protons per second). The aim of this Study was to review the design of the accelerators, to build prototypes of critical components and to update the cost and manpower estimates. The Accelerator Design Report describes the results of the Study on the design of the overall complex and on the individual subsystems. Costs and manpower are dealt with in a separate volume. In this summary we review first the overall design and then the progress on each subsystem.
