Abstract
The High Intensity Proton Accelerator Facility at PSI routinely produces a proton beam with up to 1.4 MW power at a kinetic energy of 590 MeV. The beam is used to generate neutrons in spallation targets, and pions in meson production targets. The pions decay into muons and neutrinos. Pions and muons are used for condensed matter and particle physics research at the intensity frontier. This section presents the main physics and technology concepts utilized in the facility. It includes beam dynamics and the control of beam losses and activation, power conversion, efficiency aspects, and performance figures, including the availability of the facility.
Highlights
The original proposal for the accelerator facility that is known as the PSI high intensity proton accelerator (HIPA)1, was completed 1963 [2]
Injector I was not able to deliver beam currents higher than about 180 μA, while the performance of the Ring cyclotron indicated the capability for much higher currents with low losses
The intention of this article is to present performance figures for the accelerator together with the main physics and technology concepts utilized in the facility. This includes beam dynamics and space charge effects in the cyclotrons, the control of beam losses and activation, power conversion, and efficiencies. While some of these topics are relevant only for cyclotrons, many themes are discussed that are important for any type of high intensity proton accelerator
Summary
The original proposal for the accelerator facility that is known as the PSI high intensity proton accelerator (HIPA), was completed 1963 [2]. Studies for an upgrade of the Ring cyclotron with a flattop cavity and a new injector cyclotron with a Cockcroft-Walton type pre-accelerator for beam currents of up to 1 mA were in progress while the commissioning was still ongoing [5]. The intention of this article is to present performance figures for the accelerator together with the main physics and technology concepts utilized in the facility This includes beam dynamics and space charge effects in the cyclotrons, the control of beam losses and activation, power conversion, and efficiencies. While some of these topics are relevant only for cyclotrons, many themes are discussed that are important for any type of high intensity proton accelerator. The basic physics and main parameters of the three accelerators are described
