Neutrons for Science
5.1 The first instruments
The scientists at Julich had made very advanced study of what instruments could be associated75 with the reactor. The results
of this were presented at the conference in Santa Fe mentioned earlier. The study largely influenced the choice of instruments to build. Three instruments for nuclear physics, five spectrometers for inelastic scattering and ten for diffraction and small angle scattering were the first projects started and represent about half the forty instruments foreseen. [2018 addition: a portfolio has been added at the end of the chapter that shows some of the ILL’s instruments.]
5.1.1 Nuclear Physics
Three instruments were built which were extensions of those in operation at Munich, Jülich and Risø (the Danish reactor cen- tre had a collaboration with Jülich). Experts from these reactors helped in the construction work at the ILL.
1. “Lohengrin” a mass spectrometer for fission fragments This instrument separates fission products as a function of their
mass, energy and charge. It was designed and constructed by industry under the supervision of Eberhard Moll (arrived at the ILL in 1968, coming from Maier-Leibnitz’s laboratory in Garching). The very large instrument was the origin of Maier-
