The call and ACME – The first call is opened in the framework of the ACME – Astroparticle Centre for Multimessenger studies in Europe. ACME  enables transnational access (TA) on the basis of scientific merit to a wide range of complementary astroparticle, high-energy and astronomical Research Infrastructures to perform new science of multi-messenger astrophysics.

For more information on ACME see the ACME portal.

How to prepare a proposal – The call is open to all external users, with no restriction. External scientists may act as Principal Investigators (PI) or co-Investigators (coI) on the proposals, provided they agree to a Non-Disclosure Agreement with the KM3NeT collaboration.
