One day workshop: Atomic, Molecular and Optical Physics at LCLS
1st July 2009 10 am – 5 pm
Walton Rooms A & B, Cockcroft Institute, Daresbury Laboratory
Format Location Travel and bursaries Registration
Organisers AMO LCLS background
Sponsored by the Photon Science Research Insititute
Purpose
The Linac Coherent Light Source (LCLS) at the Stanford Linear Accelerator Centre (SLAC) is a new free electron laser that will produce femtosecond pulses of light in the 800 eV to 2 keV photon energy range. The availability of short pulse, high intensity radiation in the XUV promises to bring many new scientific opportunities, and this new light source has an end station specifically designed for Atomic, Molecular and Optical Physics experiments. User operations with this AMO instrument begins in August 2009. In September '08 the STFC and LCLS signed a memorandum of understanding enabling access to the AMO facility for UK scientists.
This one day workshop aims to develop UK activity with the LCLS AMO instrument. The keynote speaker at the workshop will be the LCLS AMO instrument lead scientist, John Bozek. The workshop will bring together AMO scientists in the UK to learn about LCLS AMO capabilities with a view to developing collaborations and proposals for work at the LCLS leading to UK activity at the LCLS AMO end station. Interested academics at any stage of their career are encouraged to attend.
Workshop Format
The workshop will include presentations by leading AMO scientists with experience of working with free electron laser light sources. These speakers and their presentation titles are:
- John Bozek, lead scientist for the AMO instrument at the LCLS.
Status of the LCLS and first experiments using the AMO instrumentation
- Marc Vrakking, FOM Institute for Atomic and Molecular Physics.
Pump-probe spectroscopy using XUV/x-ray free electron lasers
- Klaus von Haeften, Department of Physics and Astronomy, University of Leicester.
Helium droplet beam endstations
- Kiyoshi Ueda, Tohuku University, Japan.
3D momentum imaging for FEL experiments
The aim of the workshop is to facilitate discussions leading to collaboration and proposal development, and there will be a number of led discussion sessions during the day. Attendees are welcome to bring along a slide or two to contribute to the discussions.
Location
This meeting will be held in the Walton Rooms A & B, Cockcroft Institute, Daresbury Laboratory. More information on getting to Daresbury Laboratory can be found at http://www.stfc.ac.uk/About/Find/DL/Introduction.aspx.
Travel and subsistence bursaries

The AMO LCLS instrument - background
The AMO instrument is being designed to utilize soft x-rays from the LCLS in the photon energy range over approximately 800-2000 eV. The instrumentation is designed to study the interaction of the LCLS FEL radiation with the simplest forms of matter, atoms, molecules and clusters. The AMO beamline design includes:
- focusing mirrors to achieve a beam size of a few microns in the interaction region
- an experimental chamber with:
- a skimmed pulsed supersonic gas jet
- three ion spectrometers: - a Wiley-McLaren type integrating ion spectrometer
- a Velocity Map Imaging ion spectrometer
- a momentum resolving ion spectrometer
- five time-of-flight electron energy spectrometers
- two x-ray fluorescence spectrometers - Diagnostics chamber including: - effusive gas jet source
- magnetic bottle time-of-flight electron spectrometer
- fluorescent beam screens to record position of beam
- pulse energy monitor
