“…The 590 MeV proton beam of HIPA [1] with currents up to 2.4 mA serves four target stations, two spallation targets and two meson production targets. The Ultracold Neutron Source UCN gets the full beam for a few seconds every 5 minutes, whereas the neutron spallation source SINQ is located at the end of the main beam line after the two meson production targets M and E [2]. Therefore, the beam on the SINQ target already lost part of the energy and current on its way through target M and E. While this effect is negligible for target M due to the small effective target thickness of 5 mm graphite, the influence of target E (either 40 or 60 mm thick graphite), on the beam is substantial.…”

The high intensity proton accelerator complex (HIPA) at the Paul Scherrer Institute (PSI) delivers a 590 MeV CW proton beam with currents up to 2.4 mA (1.4 MW). Besides two spallation targets for thermal/cold neutrons (SINQ) and for ultracold neutrons (UCN), the beam feeds two meson production targets Target M and Target E. The targets consist of graphite wheels of effective thickness 5 mm (M) and 40/60 mm (E). The target stations M and E are of quite different design; however, both of them rotate at 1 Hz to dissipate the heat (20 kW/mA for the 40 mm target E) efficiently. Recent progress was made by a new type of bearings and a new target geometry able to increase the rate of surface muons by up to 50 %. This is also foreseen for the upgrade of the target station M within the High Intensity Muon Beam (HIMB) initiative aiming to increase the surface muons available for experiment by two orders of magnitude. HIMB is part of IMPACT (Isotope and Muon Production with Advanced Cyclotron and Target Technology), an application for the Swiss Roadmap of Research Infrastructure.

“…1 is driven by an accelerator chain consisting of a Cockcroft-Walton-type preaccelerator and two isochronous separate sector cyclotrons, namely the 72 MeV Injector II and the Ring cyclotron, providing a 590 MeV proton beam of up to 2.4 mA. This high intensity beam is either send to the ultra-cold neutron source "UCN" [5][6][7][8][9][10][11] or via two graphite targets, the 5 mm thick Target M and the 40 − 60 mm thick Target E [12][13][14],…”

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.

“…Four 50.6 MHz cavities accelerate the beam to its final kinetic energy of 590 MeV. After about 180 turns in the cyclotron, the beam is extracted with an electrostatic element (see Figure 2.2) and sent to the meson production targets [8]. These targets are Figure 2.2: Pictures of the electrostatic extraction channel EEC without (left) and with attached aluminium shroud (right).…”

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.
