Discover how technological advances for high-energy physics have become essential tools for modern medicine. 

This series of short talks is given by Early-Career Researchers working on projects related to diverse medical applications that arise from technology developed at CERN and in high-energy physics.

In this seminar 3 ECRs working on the NIMMS project will share their work.

The Next Ion Medical Machine Study (NIMMS) project outlines an umbrella R&D programme for the development of critical accelerator technologies related to ion therapy; the programme builds on existing activities and on core CERN competences.  


This seminar will take place on zoom:


Passcode: NIMMS

There are very limited seats available in the room, please contact us if you'd like to attend.

      Design of a ‘bent linac’ for carbon ion therapy 15m

      High-frequency linear accelerators are very suitable for carbon ion therapy, thanks to the reduced operational costs and the high beam quality with respect to synchrotrons, which are presently the only available technology for this application.
      The ‘bent linac’, based on the latest accelerators technologies developed at CERN, introduces an innovative design tailored to better fit the accelerator footprint into existing hospital facilities and, at the same time, to provide a high quality, stable beam in the full range of operational energies.

      How to design extraction from the NIMMS synchrotron 15m

      Abstract: The extraction of heavy ions for hadron therapy is crucial to provide a good quality beam which meets medical requirements. The design choices of slow extraction are explained in this talk, and extraction simulations results from a normal-conducting synchrotron are compared to results from existing hadron therapy accelerators.

      Beam optics studies for GaToroid 15m

      GaToroid is a novel concept of a beam delivery system for hadron therapy. It comprises toroidal magnets to bend and focus the beam onto the patient location from a discrete number of directions. As GaToroid operates in a steady-state and consists of superconducting magnets, it can significantly reduce the complexity, cost, weight, and footprint of charged particle therapy systems.

      Recent progress on the beam dynamics studies for GaToroid is presented. The incoming angles, and hence the reference trajectories for beams of various energies, are automatically determined. Subsequently, 3D particle tracking studies are performed to understand the beam optics to the first order. The linear transport matrix coefficients offer insights into the beam behaviour in the complex system and point towards the design optimization of the magnetic coils. Ultimately, some considerations on the upstream beamline elements are shown.
