denied this, maintaining the plutonium-239 content of the material was below 92 percent, which meant it was not weapons-grade material. The idea was rather to use the material obtained from reprocessed fuel rods of the Diorit research reactor, which was operated from 1960 to 1977, to develop a new generation of fuel element types for nuclear power plants. This, however, never happened. By the time it was decided, in 2011, to phase out nuclear power, it had become clear that there was no further use for the material in Switzerland. The Federal Council decided at the Nuclear Security Summit in 2014 to close the Swiss plutonium storage facility. A bilateral agreement between the two countries meant the plutonium could then be transferred to the US for further storage. In July 2017, the three-dimensional alignment of magnetization inside a three-dimensional magnetic object was investigated and visualized with the help of the SLS without affecting the material. The technology is expected to be useful in developing better magnets, for example for motors or data storage. Joël François Mesot, the long-standing Director of PSI (2008 to 2018), was elected President of ETH Zurich at the end of 2018. His post was temporarily taken over by the physicist and PSI Chief of Staff Thierry Strässle from January 2019. Since 1 April 2020, the physicist Christian Rüegg has been Director of PSI. He was previously head of the PSI research division Neutrons and Muons. Numerous PSI spin-off companies have been founded over the years to make the research findings available to the wider society. The largest spin-off, with 120 employees, is the DECTRIS AG, founded in 2006 in nearby Baden, which specializes in the development and marketing of X-ray detectors. SwissNeutronics AG in Klingnau, which sells optical components for neutron research facilities, was founded as early as 1999. Several recent PSI offshoots, such as the manufacturer of metal-organic frameworks novoMOF or the drug developer leadXpro, have settled close to PSI in the Park Innovaare, which was founded in 2015 with the support of several companies and Canton Aargau. Research and specialist areas PSI develops, builds and operates several accelerator facilities, e. g. a 590 MeV high-current cyclotron, which in normal operation supplies a beam current of about 2.2 mA. PSI also operates four large-scale research facilities: a synchrotron light source (SLS), which is particularly brilliant and stable, a spallation neutron source (SINQ), a muon source
