In-kind contributions

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 Administrative and Finance Committee). In the following table, the total values for each country's IKCs are listed.
