23rd International Vacuum Congress


IVC-23 | 23rd  international vaccum congress | Sydney Australia

From the President of the Vacuum Society of Australia

Welcome to ICV-23

The International Vacuum Congress is IUVSTA’s (the International Union of Vacuum Science, Technique, and Application) main meeting that has been held every three years (more or less) since 1959! The meeting see’s around 1200-1500 participants and has a vibrant exhibition of around 80-120 vendors. It brings together the entire community of scientists, engineers, teachers, sales people, industrialists that work in areas that are connected directly with, or are heavily influenced by, the science and technology of vacuum.

The meeting has become a hub and celebration of the enabling of modern technology, from medical and food technologies and science, through to quantum computing, and space flight (for example current plasma thrusters for deep space flight). The congress can be seen therefore as the thread that pulls together some of the most important scientific developments and many of the exciting technologies being worked on in Australia and abroad.

Host City


Built around the largest, most beautiful harbour in the world, Sydney is undoubtedly the most exciting city in the southern hemisphere. It is the largest and oldest city in Australia which is home to over 4.5 million people. From the iconic, heritage-listed Opera House to the golden beaches stretching into the Pacific Ocean – Sydney is the place for everyone.

Climb the Sydney Harbour Bridge to see panoramic views from the top of this Australian icon, visit the historic ‘Rocks’ area, or take a surfing lesson at Bondi Beach – famous for its golden sands and turquoise waters. There’s so much to see and do!
