      abstract     = {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.},
