Accelerator Modelling and Advanced Simulations (AMAS)

Particle accelerators have enabled some of the most remarkable scientific discoveries of the twentieth century and form one of the foundational research pillars of PSI. Accelerator-based systems are now being developed to address challenges of major societal relevance in the fields of energy, biology and the environment. Given their scientific and technological importance, the design, optimisation and operation of accelerator facilities require the most advanced numerical methods and high-performance computing tools.

Computational accelerator physics capable of start-to-end simulations is inherently demanding. It requires close interdisciplinary collaboration across physics, numerical mathematics and computational science, as well as access to substantial computational resources. The AMAS Group is part of the Laboratory for Scientific Computing and Modelling (LSM) within the Center for Scientific Computing, Theory and Data (SCD).

Mission

AMAS advances accelerator research by bridging qualitative physical insight and quantitative modelling. We integrate and extend the latest developments in:

  • Accelerator physics

  • Numerical modelling

  • High-performance computational science

The AMAS group develops, designs and adapts simulation tools tailored to the requirements of realistic accelerator modelling at PSI. Our research focuses on methods and algorithms for beam dynamics that address the specific modelling challenges associated with existing and upcoming accelerator projects. We use these tools to calibrate physical models and to deepen the understanding of machine performance. The group also engages in new accelerator initiatives both at PSI and within the broader scientific community.

AMAS further contributes to education by supervising summer students and MSc/PhD theses — primarily at ETH Zurich — in computational accelerator physics and high-performance computing, framed by the wider context of multi-scale modelling.
