AB  - After three years into the strategy discussion of Forschungszentrum Jülich (FZJ) and the uncertainties comingalong with the conclusion to discontinue the Institute für Kernphysik (IKP) within FZJ for the staff andstudents of IKP, the year 2018 turned out to be a time of decisions: The Supervisory Boards (Aufsichtsrat)of FZJ and of GSI Darmstadt decided to transfer IKP-1, IKP-2, IKP-4 and IKP-TA from FZJ to GSI as ofJanuary 1, 2021. This is to secure the IKP expertise – in our view: accelerator physics (i. p. for storagerings), hadron physics with antiprotons, precision physics for symmetry investigations, neutrino physicsand polarization technologies – for the German physics community. The implementation, which was giventhe project name “TransFAIR", turns out to be a major administrative and regulatory effort, and it remainsto be seen if the sought date can be met.Scientifically, the year 2018 was again a very successful one:• The JEDI collaboration has conducted a first precursor experiment to study the electric dipole moment(EDM) of the deuteron in COSY, after installation and commissioning of an RF Wien filter. Thishas been one principal goals of the ERC Advanced Grant “srEDM" and can be considered a majormilestone towards EDM searches for charged particles in storage rings.• The CPEDM collaboration, with major contributions from the JEDI collaboration, submitted a paperto the “European Strategy for Particle Physics" (ESPP) update, outlining the strategy for a search forelectric dipole moments (EDM) of charged particles in storage rings with unprecedented sensitivity.• The Borexino collaboration, with major input from the Jülich group, has recently published the firstcomprehensive measurement of solar neutrinos produced along the pp-chain, a sequence of nuclearfusion reactions responsible for about 99 percent of solar energy. In particular, Borexino measuredthe rates of pp, pep, 7Be, and 8B neutrinos and provided limits both on the so called hep neutrinos aswell as on neutrino contributions from the CNO-cycle.Preparations for FAIR are also on track:• As a major step towards commencement of the FAIR experiments, components of the FAIR experimentshave been extensively tested to perform physics measurements at existing facilities. IKP hasnow completed all STS1 Straw Tube modules needed to enable spectroscopy studies of hyperons atthe combined HADES/PANDA FAIR-Phase 0 experiment.• COSY once again proved to be an invaluable tool for investigating hardware developments intendedfor later use at the FAIR facility. The full sized stochastic cooling system developed for HESRreached the design parameters running with the newest generation of the PANDA target provided byMünster University.• Pre-assembly of HESR components is a considerable effort alongside the COSY operation / maintenanceand HESR design / production tracking. 75% of the dipole magnets are presently in the storagehall close to FAIR. Two assembly lines for the girders between the dipole magnets are being set up.In 2018, we celebrated the 70th birthday of Rudolf Maier, long-term director of IKP-4, who retired in early2014, with a scientific colloquium at IKP.Finally, I would like to take this opportunity to thank everyone for his/her contributions to our scientificand strategic ventures – most important, that we all have stuck together until now: let’s see, whether IKPwill have a future that we are hoping for.
