“…Injector II is a 72 MeV high-current isochronous cyclotron with four separate sectors [66][67][68][69][70][71]. After extraction, the beam is send via the 72 MeV-beamline "IW2" to the so-called "Ring-cyclotron" [72][73][74][75][76][77][78] where it is accelerated to 590 MeV.…”

We report about the methods used in, and the performance of, the new fast and light-weight linear beam transport program MinT. MinT provides, beyond the usual linear ion optics, methods to compute the effects of beam degradation, multiple scattering and beam collimation. This is specifically important in facilities where the ion beam passes matter, for instance in proton therapy beamlines with an energy degrader as in the Proscan facility at PSI, but also for modeling the beam traversing the Muon-and Pion-production targets of the Paul Scherrer Institut's high intensity proton accelerator (HIPA). MinT is intended to be useful as a support tool for the HIPA and Proscan control rooms. This requires to have useful results within a few seconds. Hence simplicity and speed of calculation is favored against higher accuracy.MinT has been designed not only to replace the FORTRAN 77 codes TRANSPORT and TUR-TLE, but to combine and extent their capabilities. MinT is a byte-code-compiler which translates an input language, described by syntactic rules. This allows for control structures like "if-then-else" or "while"-loops, thus providing a high flexibility and readability.

“…The performance of the Ring cyclotron was steadily improved, especially the extraction efficiency. In the beginning, only a well-centered beam was able to pass the Walkinshaw-resonance without substantial beam loss, as the beam had to pass the resonance four times before extraction [5,33]. A modification of the tune diagram by an improved setting of trim coils reduced this to two fast passages through the resonance and allowed relaxation of the requirement of beam centering [34,35].…”

“…Injector I was not able to deliver beam currents higher than about 180 µA (originally 100 µA specified), while the performance of the Ring cyclotron indicated the capability for much higher currents with low losses. Therefore, 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]. At this stage, it was estimated that the Ring cyclotron had the potential to accelerate currents of up to 2−4 mA [6].…”

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.

“…The proton ring cyclotron at the High Intensity Proton Accelerator complex (HIPA) at PSI first went into operation in 1974 [25]. It accelerates protons at a frequency close to 50 MHz from a kinetic energy of 72 Mev to just below 600 MeV.…”

Here is a short paper on precision physcis experiments at low energies. Such experiments use methods of nuclear, particle and atomic physics providing some of the most sensitive tests of our present best theories of nature. Hoping that this is most accessible, I have chosen an illustrative approach, giving 6 examples of such experiments with neutrons and muons addressing various aspects of the known fundamental interactions and open issues. The list of references puts emphasis for some examples more on the historic, original publications, for others on the latest results and sometimes just refers to review articles. It is not aiming at the most comprehensive picture but at attracting the reader's interest and providing starting points for further studies.Focus Point on "Rewriting Nuclear Physics Textbooks: Basic Nuclear Interactions and Their Link to Nuclear Processes in the Cosmos and on Earth" edited by N.
