Compact (EUV & X-Ray) Light Sources

23 March 2022 – 25 March 2022 Kempinski Hotel Corvinus Budapest, Budapest, Hungary

Emerging, compact extreme-ultraviolet and x-ray sources that exhibit high brightness and are small enough to be installed in laboratories at educational and research institutions, manufacturing facilities, hospitals, and other suitable sites, will revolutionize scientific and technical disciplines, complementing both existing and future large scale synchrotron radiation and free-electron laser sources. Applications span a wide range including biomedical, semiconductor manufacturing, fundamental and applied research, environmental engineering, industrial non-destructive testing and screening, and defense and security.

The aim of the Compact EUV and X-ray Light Source meeting is to assemble experts in both source technologies and their applications to present and exchange ideas and improve community wide understanding of current and future source capabilities, and current and future application needs. At this meeting the latest results in the development of these sources will be presented as well as descriptions of efforts to mature the technology so that they meet the requirements needed in order to transition the technology to industrial and medical applications. Conference topics will include the latest development in source technologies and applications in the EUV through hard-ray regime.

The collocation with the High-Intensity Sources and High-Field Phenomena (HILAS) and Mid-infrared Coherent Sources (MICS) meetings provides a unique opportunity to expand interaction with multidisciplinary groups that shares a broad range of interests and goal.

Plenary Session

Scott Diddams

National Institute of Standards & Technology, USA

An Optical Sampling Oscilloscope

I will intorduce the principles of a sampling oscilloscope based on dual optical frequency combs that has bandwidth of 100THz. Applications in precision infrared spectroscopy, microscopy and quantum electric field metrology will be described.

About the Speaker

Scott Diddams is a Fellow of the National Institute of Standards and Technology and Professor at the University of Colorado Boulder, where he carries out experimental research in the fields of precision spectroscopy, nonlinear optics, microwave photonics and ultrafast lasers. He has pioneered the use of optical frequency combs for optical clocks, tests of fundamental physics, novel spectroscopy in the visible and mid-infrared, and ultralow noise frequency synthesis. In recent years, a focus has been on infrared frequency comb sources as well as high repetition rate electro-optic and microresonator frequency combs, which are being explored for applications in spectroscopy, microwave photonics and astronomy. Among many awards, Dr. Diddams received the Department of Commerce gold and silver medals for "revolutionizing the way frequency is measured” as well as the Presidential Early Career Award in Science and Engineering (PECASE) and the IEEE Rabi award. He is a Fellow of Optica and the American Physical Society.

Chang Hee Nam

Ultrahigh Intensity Laser for strong field physics research

Ultrahigh intensity lasers have opened up research opportunities in charged particle acceleration and strong field quantum electrodynamics. By tightly focusing a wavefront-corrected multi-PW laser the record-breaking laser intensity of 1023 W/cm2 was realized at CoReLS.

The European XFEL: new science opportunities and first results

The EuXFEL is the first hard XFEL powered by a superconducting accelerator. Six instruments started user operation between 2017 and 2019. I will report first results from early experiments, and comment on important challenges ahead.

About the Speaker

Sakura Pascarelli received a Laurea in Physics at the University La Sapienza (Rome, Italy) and a PhD degree in Physics at the University Joseph Fourier (Grenoble, France). After joining the European Synchrotron Radiation Facility (ESRF, Grenoble, France) in 1993, her scientific career evolved around the development of methods to probe the local and electronic structure of condensed matter by synchrotron X-rays. In the past twenty years, her main scientific interest was the investigation of matter at extreme conditions of pressure, temperature and magnetic fields using principally X-ray Absorption Spectroscopy and X-ray Magnetic Linear and Circular Dichroism. She was in charge of the x-ray absorption spectroscopy beamlines ID24 (1997-2019) and BM23 (2000-2019), Head of the Electronic Structure and Magnetism Group (2012-2015) and Head of the Matter at Extremes Group (2015-2019). In September 2019 she joined the European XFEL (Hamburg, Germany) as Scientific Director responsible for the development of the scientific program on the four short-waved hard X-ray instruments.

Technology Showcase: From EUV to SXR: Next-Gen Metrology and Inspection Sources

Wednesday, 23 March 10:00 – 10:20

Speaker: Bill Solari, Senior Product Manager, EUV,  Energetiq Technology

As a leader in extreme ultraviolet (EUV) source development, Energetiq has over 50 sources in the field being used in materials research and high-volume manufacturing applications. Next generation metrology and inspection sources need higher power, higher numerical aperture (NA) and more brightness. Beyond EUV, emerging soft x-ray (SXR) technology is unlocking a small footprint alternative to synchrotrons with a lower cost-of-ownership and higher availability. This showcase will address the challenges of current technology and solutions that will reveal the future of metrology and inspection sources.

Lasers and Free-Electron Lasers Session

Thursday, 24 March 09:00 – 11:00

Conventional lasers and laser based secondary sources as well as Free-Electron Lasers have made tremendous progress over the last decades in terms of key parameters such as pulse duration, average power and energy as well as wavelength coverage. In addition conventional lasers are indispensable tools in advanced Free-Electron Laser facilities and related experiments. This session brings together key players in these areas to review progress and speculate about possibilities for the future given recent advances in both fields.
