Postdoctoral fellow (f/m) in the Beam Dynamics group

Within the framework of a collaboration with CERN on Future Circular Collider (FCC-ee) feasibility studies, you will investigate the performance of the Local Chromaticity Correction optics (LCC) proposal against errors and demonstrate that FCC-ee can be commissioned and operated with the LCC optics. As part of this work, you will develop numerical tools and correction methods to support these investigations and validate them on the ESRF-EBS storage ring.

Your tasks will be the following:

·         Perform beam dynamics simulations to characterize the dynamic aperture (DA) and momentum aperture (MA) of the FCC-ee collider and perform non-linear optimizations to maximize them;

·         Develop correction schemes and tuning tools and algorithms to provide efficient commissioning and robust operation and validate them on the ESRF-EBS storage ring;

·         Evaluate LCC optics performances after commissioning-like sequences of tuning in the presence of realistic errors such as short and long range alignment errors and magnetic errors with particular attention to the magnets close to the interaction points. Define a table of tolerated errors for the LCC optics;

·         Develop the necessary simulation tools based on existing python codes used at ESRF such as pyAT or pySC;

·         Publish the results in accelerator physics related journals and conference proceeding.

You will be requested to attend in person collaboration meetings at CERN on a regular basis and part of your work could be carried out in shifts, following ESRF regulations.
