Editing HERA (particle accelerator) (section)

== International project HERA ==
The construction of HERA was one of the first truly internationally financed projects of this magnitude. Previously, the construction of scientific facilities was always financed by the country in which they were located. Only the costs for the experiments were borne by the conducting national or foreign institutes. Due to the enormous scope of the HERA project, many international institutions agreed to participate already in the construction.

More than 45 institutes and 320 corporations participated in the construction of the facility with donations of money or materials, and more than 20% of the costs were borne by foreign institutions.

Following the example of HERA, many large-scale scientific projects have since then been financed jointly by several countries. This model has become established and international cooperation is moderately common in the construction of those facilities.<ref>{{cite web |title= Lohrmann, Erich and Söding, Paul: Von schnellen Teilchen und hellem Licht |url= http://www-library.desy.de/preparch/books/DESY50-Lohrmann-Soeding-secured.pdf#page124 |publisher= Wiley-VCH |access-date=4 May 2023}}</ref>
