Workshop 1: Electron Beam Size Measurements

The assessment and optimization of electron beam size in synchrotron light sources continues to be highly relevant to the successful exploitation of the source.  As sources of higher brightness have been developed, the accurate measurements of the source electron beam size, particularly in the vertical direction, has provided essential input to the optimization.  The limitations of optical based techniques have been used; pinhole optics; fresnel based systems; interferometry; etc.  Such techniques have much common ground between the accelerator and synchrotron light instrumentation communities.

Date: April 24 (Tuesday), morning half a day

Chairperson: Victor P. Suller (CAMD/Daresbury), and Jeff Corbett (SLAC)

Objectives:

• Review the present status of techniques used for measuring electron beam source size in bending magnets and insertion devices;
• Consider new ideas for measurement of source size applicable to new sources of extremely high brightness;
• Encourage exchange of ideas between the synchrotron light accelerator and instrumentation communities;
• Document the workshop conclusions for the general benefit of the wider community.

Workshop 2: Polarization and Coherence

For a long time, researchers did not make use of the (besides the continuum spectrum) most valuable properties of synchrotron radiation: polarization and coherence. These properties allow a broad range of new and exciting experiments in various research areas! Over the last years, several new developments, e.g. the use of special types of insertion devices, has pushed this research area forward opening sometimes unexpected opportunities such as lenseless holography, just to name one!

Date: April 24 (Tuesday), morning half a day

Chairperson: Eric Dufresne (APS/ANL) and Josef Hormes (LSU/CAMD, Bonn University)

Objectives:

• Review the present status of experiments making use of polarization and coherence
• Consider new ideas for future experiments
• Discuss the need for new experimental techniques and equipment
• Encourage SR-users, to make actually use of these new opportunities.

The Organizers would appreciate appropriate contributions for this workshop. Contact Eric Dufresne or Josef Hormes if you wish to speak at the workshop or if you wish to nominate someone as a speaker.

Workshop 4: Synchrotron Radiation and Nano-Technology

Synchrotron radiation offers a wide range of possible applications in nano-technology including nano-lithographic patterning for fabricating nano-size structures and a number of spectroscopic tools with nanometer spatial resolution for analyzing the electronic and geometric properties of matter. For example the spatial resolution achieved in the VUV/X-ray range is now well below hundred nanometers enabling the investigation of various electronic, geometric, and magnetic properties of nano-sized areas and nano-particles.

The goal of this workshop is to present ongoing efforts connecting synchrotron radiation and nano-technology and to stimulate a discussion about future trends and requirements to further improve the capabilities.

Date:   April 24 (Tuesday), afternoon – half a day

Chairperson:  Jost Goettert (CAMD), Josef Hormes (LSU/Bonn University)

Objectives:

• Review the present status and future perspectives for nano-lithography for both silicon – technology and MEMS/NEMS
• Present status of ‘nano-spectroscopic’ sources and beamlines
• Discuss the status, achievements and perspectives of various focusing techniques (mirrors, lenses, zone plates etc.) in the soft and hard X-ray region
• Present status reports of high resolution PEEM activities
• Discuss results from spectroscopic investigations with “nanometer” resolution from different areas (Biology, Materials…).

The Organizers would appreciate appropriate contributions for this workshop. Contact Jost Goettert or Josef Hormes if you wish to speak at the workshop or if you wish to nominate someone as a speaker.

Workshop 5: New concepts for Insertion devices

Insertion devices are crucial for the operation of third generation synchrotron radiation facilities as the majority of experiments are using radiation from these devices and not from bending magnets. They allow not only to modify the characteristic energy of the spectral distribution of SR (Wigglers and wavelength shifters) but also to manipulate in a defined way the polarization properties of the emitted radiation (elliptical undulators). Though insertion devices are now used for more than 20 years, there are still new and exciting developments that help improving the characteristics and possible applications of these devices.

Date:   April 24 (Tuesday), afternoon – half a day

Chairperson:  M. Fedurin (NSLS, BNL) and J. Hormes (CAMD, Bonn University)

Objectives:

• Review the present status and future applications of superconducting mini-undulators
• Discuss the challenges and limitations of vacuum insertion devices
• Consider new ideas for “elliptical insertion devices” to control polarization properties and other insertion devices (high field wigglers etc.)
• Encourage exchange of ideas and wishes between the “light users”, designers of insertion devices and machine operators;
• Document the workshop conclusions for the general benefit of the wider community.
• Invited speakers include:
• Dr. D. Dölling, Accel GmbH
• Dr. T. Tanabe, NSLS/BNL
• Dr. E. Johnson, ADC Inc.

This Workshop is complete with regard to organization and speakers. No contributed papers can be accommodated because of time constraints.
