Abstract

This chapter provides an overview of the studies in nucleon research with the TRIUMF cyclotron. TRIUMF is an isochronous, 6 sector, A.V.F., H¯ cyclotron that is designed to accelerate 100 μA of H¯ ions to an energy of 500 MeV. The chapter presents an impression of the size of the TRIUMF magnet and the initial experiment layout. Initially two simultaneous beam lines are being provided, one feeding a meson area and terminating in a combined slow neutron facility, activation facility, and beam dump; and the second feeding a proton area. In the experiment, two beam lines are developed in the proton area. The availability of good quality proton beams, both as energy spread and emittance, from the TRIUMF cyclotron leads to the formation of a working group to produce design specifications for a high resolution proton spectrometer. The chapter also highlights various proposals for few nucleon experiments with nucleon beams and meson beams, which are: measurement of the differential cross section for free neutron–proton scattering and for the reaction D(n,p)2n; measurement of the polarization in free neutron–proton scattering; radiative capture of pions in light nuclei; and measurements of triple-scattering parameters of the free neutron–proton system.
