The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of matter and materials, energy and environment and human health. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2100 people.

The Radionuclide Development Group is preparing a proposal for a new radioisotope target station to produce Terbium radioisotopes. At the Large Research Facilities Division, we are investigating the possibility to continuously split off a fraction of high intensity the 590 MeV beam and direct this towards the new isotope production site. It has to be investigated if an already existing splitter can be used for this. To understand the feasibility of this proposal, realistic physics and beam loss simulations beamline have been started. In this project, these simulations will be extended to the new beamline and target. The simulations will be compared with beam measurements.

The simulations will be done with Beam Delivery Simulation (BDSIM), a Geant4 based tool that enables the simulation of not only beam transportation through magnets, but also particle passage through components like the splitter septum and collimators. Furthermore, BDSIM facilitates user built elements with special electromagnetic fields, which enable modelling of the electrostatic beam splitter. With a model including all elements from beam splitter to target, BDSIM simulation delivers an optimal and complete simulation of the beam along the complete line. Beam profiles, beam transmission, energy spectra and power deposits can be generated.

For this project we are looking for a
