New Research Associate joins the QUASAR Group

Published on

Dr Aaron Farricker started his new role as a research associate with the QUASAR Group in October 2020, where he will work on investigating beam dynamics in RF including; studies of collective effects, longitudinal beam dynamics in both low and high energy storage rings.

In July 2012, Aaron graduated from the University of Manchester with a Master’s degree in physics; with his project he worked alongside the particle physics group attempting to constrain the parton distribution functions using measurements of the forward-backward charge asymmetry of the Z boson in the ATLAS detector. In September 2012 he joined the Accelerator Physics group at the University of Manchester to carry out his PhD studies; this work focused on the impact of higher-order mode excitation on the beam stability in the LINAC of the European Spallation Source (ESS). This included extensive beam dynamics and radio frequency (RF) simulation.

Aaron then went on to join the beams and RF section A in the RF group at CERN in June 2017, which saw him in a role where he was responsible for understanding the beam-coupling impedance in the Super Proton Synchrotron, using RF modelling and RF measurements as well as measurements of the longitudinal behaviour of the beam. In addition to this he also performed extensive measurements and modelling of high frequency RF systems in the Proton Synchrotron which will be used to improve the active feedback moving into the High-Luminosity LHC era.

We would like to warmly welcome Dr Aaron Farricker into the QUASAR Group!
