The Australian Synchrotron has been saved from oblivion after the federal and state governments threw the research facility a $100 million lifeline.

Last year's federal and state budgets failed to provide the internationally recognised facility with ongoing funding, raising concerns about its future.

The joint federal-state agreement, to be announced today provides a $69 million contribution from the Commonwealth and a $26 million contribution from Victoria. New Zealand is also expected to contribute.

Federal Science Minister Chris Evans said the funding would allow the facility, which conducts about 500 experiments a year, to continue.
