Senior Experimental Scientist

STFC - The Science and Technology Facilities Council - Rutherford Appleton Laboratory

Full time/part time (min 25hr/wk) and flexible hours considered

About Us

The Science and Technology Facilities Council (STFC) is one of Europe’s largest research organisations. Through combining world-class facilities with major international collaborations and some of the world’s most talented staff, we’re driving ground-breaking advances in science and technology.

STFC’s Central Laser Facility (CLF) provides advanced laser research facilities for the UK and international scientists. The CLF has two ultrafast science groups, Artemis and Ultra, who are jointly developing a new high repetition rate ultrafast pump-probe facility. Artemis focuses on ultrafast laser and extreme ultraviolet (XUV) science, using XUV pulses produced through high harmonic generation, for experiments in physical sciences. Ultra generates mid-infrared pulses for ultrafast vibrational infrared and Raman spectroscopy, with applications in chemistry and life sciences.

About The Role

The CLF is now seeking an individual with a background in ultrafast science, synchrotrons or x-ray free electron lasers to a permanent position as Senior Experimental Scientist on Artemis. Working as part of a small team of scientists and engineers, you will be developing and carrying out time-resolved experiments using high harmonics. Part of your time will be spent working with university research groups who are using the facility, by planning and guiding experiments and contributing to data analysis and paper production. You will also be designing and building a new XUV beamline to exploit high harmonics at 100 kHz, where you will manage a project work-package and the associated budget.

You will be strongly encouraged to pursue your own scientific research programme, typically in collaboration with university partners, to write papers, apply for facility beamtime, and to attend and present at conferences.


  • designing and leading commissioning of a beamline for time-resolved experiments with high harmonics at 100 kHz
  • contributing to experiments carried out on Artemis by working with university user groups and the Artemis team to design and plan experiments and then guiding and assisting in the lab and with data analysis and paper production
  • identifying and supporting new science capability and programmes on the end stations
  • leading and/or collaborating in facility user research and development programmes.

About You

You will need to be an experimentalist, with a PhD in physics and substantial postdoctoral experience (or equivalent relevant experience) and have experience designing and developing scientific instruments. You will have expertise in photo-electron or photo-emission spectroscopy. We expect you to show this with your track record of publication in peer-reviewed journals.

For appointment at the higher band, we are looking for someone who can take leadership of an area of science within the Artemis programme. You should have led a development project in an area relevant to science on Artemis and have a track record of proposals for facility time or funding. Experience of collaboration with external groups is also important. We expect you to demonstrate national or international recognition, through (for example) invited talks or committee membership.

This role requires you to work in a multi-disciplinary environment with physicists and chemists from university groups who are using Ultra and Artemis. The research topics, techniques and teams change every couple of weeks. We are looking for good communicators (diplomacy and negotiation skills are key) who can work effectively as part of a team. It’s vital that you have an interest in the science areas covered by Artemis and Ultra and a desire to develop your knowledge further.


An exceptional index linked pension scheme, 30 days leave allowance and flexible working are offered, as well as an onsite nursery, subsidised restaurant, a gym and sports facilities. A relocation allowance may also be available where applicable.
