Omega Laser Facility Users Group 2019 Workshop

Home

The Eleventh Omega Laser Facility Users Group Workshop, held 24–26 April 2019, attracted over 120 researchers from around the world. The workshop facilitates a continuing dialog among the individual users and between the users and LLE. The OLUG collectively submitted 29 Findings and Recommendations to facility management. Most of the contributed posters were given by students and postdocs (shown in inset).
