Shared facilities beyond a single university
Forschungszentrum Jülich originated in postwar West Germany’s plans to rebuild nuclear research. Engineer and North Rhine-Westphalia science-policy advocate Leo Brandt sought to concentrate funding and equipment to provide facilities beyond the resources of individual universities. In 1953, universities, the state and businesses formed an association to promote nuclear-physics research, initially aiming to build a cyclotron at the University of Bonn. The proposal subsequently grew into a shared facility for energy research and basic science.
Universities remained central to this approach. Research groups developed in surrounding institutions before supplying personnel for the new center’s institutes, whose directors initially also held university professorships. By 1960, the organizing body included the state government, five higher-education institutions and nine companies. Concentrating resources required coordination between existing university research traditions and the new institution’s management.
What the 1956 decision committed to
Brandt presented the construction proposal to the state parliament on 26 June 1956. On 10 December, the parliamentary groups of the CDU, SPD, FDP and Centre Party jointly introduced an urgent motion to advance the nuclear facility. Parliament approved construction the following day, subsequently adopted as the center’s founding date.
Motion 459 set out several levels of finance. The state government envisaged total expenditure of 42.5 million Deutsche Marks, with 10 million entered in the 1957 draft budget. To bring the facility into use promptly, the motion called for an early supply contract worth about 30 million marks for a DIDO materials-testing reactor. It also asked the finance minister to allow urgent portions of the following year’s funds to be used in the 1956 financial year. These provisions coordinated the project commitment, initial budget and procurement rather than allocating the entire construction sum immediately.
Turning a forest site into a research campus
On 19 November 1957, the state government selected the Stetternich state forest near Jülich. Local politician Wilhelm Johnen advocated for the project, hoping it would provide employment in peaceful activities. State premier Fritz Steinhoff laid the cornerstone on 11 June 1958, after which reactors, research institutes and supporting facilities were constructed.
The move to the site took place in stages. Security, fire, transport and maintenance staff first established operational support so that research groups could use the laboratories. In 1961, the biology institute moved from Münster, followed by the library, technical services and much of the administration. The center’s archival retrospective records staff increasing from 229 at the end of 1958 to 1,291 at the end of 1961. The inauguration was held on 28 September 1961; the MERLIN and DIDO research reactors started in 1962. Construction, inauguration and operation of the equipment therefore marked different stages.
From an Aachen team to plasma experiments
Nuclear research also included fusion. Wilhelm Fucks at RWTH Aachen organized fusion research in the mid-1950s. The team temporarily worked in a former Aachen textile factory before moving to Jülich in 1960. Under Fucks and Hermann Jordan, it first had to build apparatus capable of producing high-temperature plasma, then investigate magnetic confinement. Gas discharges, rapid magnetic compression and plasma instabilities became concrete objects of research.
The early goal required narrower experimental questions. A proposed fusion-energy source could not immediately become a power plant; researchers first faced plasma that changed rapidly and was hard to control. The team later continued work on pinch plasmas and shock waves under the name Institute of Plasma Physics. Theoretical calculations, apparatus construction and measurements were brought together on one site, turning university expertise into shared experimental capacity.
From personal contacts to common research programs
In 1962, Jülich established fusion-research ties with Euratom. A liaison group formed in 1963 brought cooperating research units in different countries together to exchange annual and longer-term plans and discuss directions and new projects. Laboratories retained their equipment and specialties, while planning extended beyond a single state or university.
This cooperation later involved shared major experimental equipment. The European Commission’s 2000 assessment described a joint program by Jülich, Dutch and Belgian teams around TEXTOR, studying plasma–wall interactions. Experimental staff tested coatings and material erosion, theoreticians developed transport models, and measurements supplied data to test them. The report listed about 50 professional and 70 support staff in the Jülich research unit at that time. The institution adopted the name Forschungszentrum Jülich in 1990 as its scope broadened beyond its early nuclear-facility name, while shared equipment, specialized roles and cooperation between institutions remained important ways of organizing its work.
