Title: The SLS 2.0 Upgrade

BIO
Phil Willmott is titular professor of physics at University of Zürich and Chargé de Cours at EPF Lausanne. He is the SLS 2.0 project leader for photonics and science for the Photon Science Division of the Paul Scherrer Institut. He studied single-honours BSc physics at Newcastle University before embarking on research into novel polymer optical fibres at the Hirst Research Laboratories of GEC in Wembley, London. He then moved to Switzerland where he obtained a diploma in experimental physics and PhD in physical chemistry, before carrying out two postdoctoral posts, first in collaboration with IBM Rüschlikon, and then at the ENEA institute in Frascati, Italy. He then returned to Switzerland to perform research into novel materials and nonthermal thin film growth and obtained his Habilitation in this subject in 2000.

In 2001 Willmott joined the team of the SLS project and developed surface diffraction techniques in combination with in-situ growth methods, most notably pulsed laser deposition. He pioneered the use of area detectors to accelerate and make more reliable surface diffraction data; his group was the first to report on the use of the now ubiquitous Pilatus detector. In 2014 Willmott spent a 12-month sabbatical at the CXI Instrument of the LCLS XFEL at Stanford, California.

ABSTRACT
The SLS was for over a decade the benchmark synchrotron facility regarding its performance relative to the theoretical optimal value, given the machine parameters. However, with the advent of a new-generation of storage rings, dubbed "Diffraction-limited storage-rings" or DLSRs, it has become imperative to upgrade the SLS in a likewise manner. In this didactical talk, I will explain the background concepts of DLSRs and the approach adopted by the SLS. This will be followed by examples of science at SLS that will profit most from the upgrade program.
