The Council of the European XFEL decided to welcome contributions by User Consortia to the construction of scientific instruments, to the ancillary instrumentation and to the technical infrastructure. The Council requested that contributions by User Consortia are regulated by a clear set of guidelines.
In response to this, the European XFEL issued in 2011 a Call for Expressions of Interest in contributing to the European XFEL in the form of User Consortia.
On 18 April 2011, an Information Day for prospective Consortia members took place in Hamburg. The talks have been published here.
A first round of proposals has been evaluated and in addition it was decided to keep this call open for further applications without any deadline. New proposals will be analyzed by the projects and will be evaluated with help of the European XFEL advisory committees as has been done for the first round proposals.
