Donors to the European XFEL, the largest and most powerful X-ray laser in the world, joined German Minister for Education and Research Johanna Wanka in Schenefeld on Friday for an official inauguration. «It’s a superb centre, not just for Germany or the region, but rather for the world — and also for Russia» said Wanka. «Russia has been intensely involved — it was the second largest donor — and... Еще we have cooperated very well together. This will be shown in how many young Russian trainee scientists will carry out research here» she added. The construction of XFEL started in early 2009, costing a total of amount to €1.22 billion ($1.45bn), according to official accounts. Eleven countries contributed to the project: Russia, Denmark, France, Germany, Hungary, Italy, Poland, Slovakia, Spain, Sweden, and Switzerland.
