In-kind contributions

Much of the European XFEL's equipment was provided by a variety of European institutes through in-kind contributions. The value of in-kind contributions to the facility amounted to around 50% of the total construction and commissioning budget.

Over 20 institutes across Europe contributed equipment, components, or staff to the European XFEL's construction and commissioning. Each in-kind contribution (IKC) began as a proposal that had to be reviewed by the in-kind review committee (IKRC) and approved by the European XFEL Management Board (for contributions below 1 million euro) or Council (for higher-value contributions, following recommendation by the Administative and Finance Committee).

In the table below, the total values for each country's IKCs are listed. Click on a country name in the table to get information about the contributions and the institutes involved.
