Paul Aden - project manager for UK XFEL

Paul Aden – Project Manager for UK XFEL

Paul, the Project Manager for UK XFEL, has been working at STFC Daresbury Lab for over a decade, predominantly as a Mechanical Engineer and Project Manager. In this role, he has successfully led and supervised multidisciplinary teams in the design and delivery of particle accelerators for international collaborations. Most recently Paul was responsible for the delivery of over 85% of the proton accelerator and all of the RF distribution system for Sweden’s European Spallation Source. Before joining the lab, Paul worked in the private sector manufacturing nanomechanical hardness testers, primarily in vacuum, high temperature systems for use on various surface coatings. He holds a Ph.D. in RF Plasma Modification of Carbon Nanotubes, and a BEng in Electrical Engineering, bringing a broad variety of experience to the UK XFEL project.

Edward Snedden

Edward Snedden

Edward Snedden is head of ASTeC’s Femtosecond Lasers and Timing Group. He leads a team of scientists in the development of advanced optical and electronic technology for particle accelerators, including the CLARA FEL test facility at STFC Daresbury Laboratory. His research interests include high-gradient acceleration and he is a member of the UK Plasma Wakefield Acceleration Steering Committee (PWASC). As a member of the UK XFEL leadership team, Edward is responsible for engaging with international stakeholders including overseas XFEL facilities. He will examine collaboration and investment options which can help deliver the advanced capabilities outlined in the UK XFEL Science Case. 

Storm Mathisen

Storm Mathisen 

Storm is a Senior Diagnostics and Instrumentation Engineer in the Accelerator Diagnostics and Instrumentation Group of ASTeC at Daresbury Laboratory. Since 2018 he has lead research and development in novel beam diagnostics systems and data acquisition systems, and provides expertise in electron beam diagnostics for users of ASTeC’s facilities. Prior to this, he carried out research at Lancaster University’s Engineering Department in microfabrication of W-band vacuum amplifiers. He graduated from Swansea University in 2016 with a BEng in Aerospace Engineering. 

Peter Williams

Peter Williams

Peter is work package leader for UK XFEL High Energy Beams. He is a Principal Accelerator Physicist of 18 years standing at Daresbury. Peter has made significant contributions to the understanding, design and commissioning of electron linear accelerators for UK and worldwide scientific facilities. He predominantly applies this to XFEL drivers, but also particle and nuclear physics colliders, and in the semiconductor industry. Peter is a leading expert in Energy Recovery Linacs, having more than a decade’s experience on Daresbury’s ALICE ERL driven FEL. Additionally, Peter now leads the beam commissioning of the CLARA FEL test facility. 

Neil Thompson

Neil Thompson

Neil’s main specialism is FEL physics and technology. He has made important contributions to several UK FEL projects, from 4GLS to the New Light Source and now UKXFEL. He led the design and commissioning of the UKs only (to date) free-electron laser – the ALICE Infra-Red FEL – which operated at Daresbury Laboratory from 2010 to 2016. Neil’s research focusses on methods of novel FEL output, from ultrashort pulse generation to new techniques for producing transform limited pulses at short wavelengths. Neil also designs accelerator magnets and undulators.    

Mark Roper

Mark Roper

Mark is a Principal Beamline Scientist working in the Femtosecond Lasers & Timing (FLT) group in the ASTeC department at Daresbury Laboratory. He is managing the photon beamlines and diagnostics work package (WP6) for the UK XFEL project. 

His career started on the SRS (Synchrotron Radiation Source) at Daresbury where he became a specialist in the design, modelling and operation of soft x-ray beamlines and grating monochromators. He has also developed optical systems from the THz to hard x-ray on the SRS, DIAMOND and ALICE light sources, and has worked with ultra-fast lasers on the photo-injector system on the CLARA linac. He founded the Optics Metrology Laboratory at Daresbury for measuring form and texture of ultra-precision optical surfaces. His work for the FLT group spans most aspects of optical systems from design and modelling, through engineering, to procurement and installation, and commissioning and operation. 

 

Dave Walsh

Dave Walsh

Dave is the Synchronous Sources work package lead. He first came to Daresbury as a postdoctoral researcher working on laser based longitudinal profile monitors for the CLIC project. His role as a Senior Laser Scientist is backed by an MSc and a PhD in laser science from St Andrews, and he contributes to most of the laser activities of ASTeC, as well as designing optical imaging systems. He has recently demonstrated a new electrooptic longitudinal profile measurement using CLARA. which overcomes fundamental limitations of the technique. 

 

Matt Wilson

Matt Wilson

Matt Wilson is head of the Detector Development Group and Individual Merit Scientist in STFC’s Technology Department. He has over 100 publications in the area of detector development and applications and generated multi-million pounds of research funding. His group has delivered instruments to industry, universities, synchrotrons, laser facilities, neutron sources and the European XFEL. Matt joined STFC on the graduate scheme in 2006 after completing his masters in Physics at the University of Nottingham. He was originally recruited to work on the grant which funded the HEXITEC detector and has subsequently driven the increase in TRL, developed new cameras, grown a user community and overseen new ASIC designs around similar hard X-ray technology. Matt is the STFC lead for XIDyn, a new integrating detector for Diamond II and ESRF-EBS and includes the EuXFEL in the collaboration. He has projects exploring Si and LGAD detectors for lower energy X-ray applications that, along with the hard X-ray work, is well matched to the breadth of beamlines proposed for a UKFEL.
