The COMO consortium addresses the provision of state-, size-, and isomer-selected samples of polar molecules and clusters for XFEL studies using soft and hard X-ray FEL radiation. It intends to build an molecular beam injector setup that can be attached to the European XFEL instruments, in particular Small Quantum Systems (SQS) and Single Particles, Clusters, and Biomolecules (SPB). More details can be obtained from Jochen Küpper (CFEL, DESY and Universität Hamburg) who coordinates this proposal. Further information can be found on the project website.
