IMPACT (Isotope and Muon Production with Advanced Cyclotron and Target Technology) is a proposed upgrade project for the high-intensity proton accelerator facility (HIPA) at the Paul Scherrer Institute (PSI). As part of IMPACT, a new radioisotope target station, TATTOOS (Targeted Alpha Tumour Therapy and Other Oncological Solutions) will allow to produce promising radionuclides for diagnosis and therapy of cancer in doses sufficient for clinical studies. The proposed TATTOOS beamline and target will be located near the UCN (Ultra Cold Neutron source) target area, branching off from the main UCN beamline. In particular, the 590 MeV proton beamline is intended to operate at a beam intensity of 100 uA (60 kW), requiring a continuous splitting of the main beam via an electrostatic splitter. Beam loss simulations to verify safe operation have been performed and optimised using BDSIM, a Geant4 based tool enabling the simulation of beam transportation through magnets and particle passage through accelerator. In this study, beam profiles, beam transmission and power deposits are generated and studied. Finally, a quantitative description of the beam halo is introduced.

PSI’s Injector II cyclotron is the only cyclotron worldwide that makes use of the so-called "Vortex effect", in which strong space charge forces generate the counter-intuitive effect to "roll up" bunches thus keeping them longitudinally compact. The effect has been verified by bunch shape measurements and the PIC-code OPAL. However, PSI’s new fast matrix code MinT allows to reproduce the Vortex effect by a linear matrix model which is computational much cheaper than PIC simulations, and is suitable for "online use" in Control rooms. Furthermore it provides the second moments of matched distributions.
