Marco Calvi is an accelerator physicist working since 2009 at the Photon Science Division of the Paul Scherrer Institute (PSI). He received his PhD in 2004 at the University of Geneva in the Department of Quantum Material Physics under the supervision of Prof. R. Flükiger. Then, he started his career at CERN during the construction of the Large Hadron Collider (LHC) in the domain of high field superconducting magnets. Later, he moved to EPFL for joining the ITER project and the cold cable tests of its superconducting Tokamak. At the beginning of the SwissFEL project, Dr. Calvi was hired by PSI to work on the undulator system of its first hard X-ray beamline, Aramis. Today, after more than 10 years, he is a senior scientist in the domain of accelerator-based light sources, both synchrotrons and FELs. His favourite research field is High Temperature Superconducting Undulators (HTSU).
