3.6 km underground
I suspect that this means the length of the apparatus is 3.6 km, and is located underground; NOT that the device is located 3.6 km beneath the surface of the Earth. I don't have a reference to correct this, however. LorenzoB (talk) 18:33, 22 December 2008 (UTC)

Participating countries
At the time of writing the article says there are 11 countries involved, but this is sourced to a page that lists, by my reading of it, 9 current and 3 prospective partners: https://www.xfel.eu/organization/partner_countries/index_eng.html The list in the article includes Italy and Spain but omits the UK, but on the project website all of those three are listed as "likely future shareholder[s]". The same applies to File:European XFEL countries.svg. Can anyone explain the discrepancy? Beorhtwulf (talk) 10:37, 6 September 2017 (UTC)
