      abstract     = {Aiming for highest neutron peak brightness, limits are set
                      by the capabilities of heat removal and for pulsed sources
                      even more bythe instantaneous power impact. In this respect,
                      the long pulse ESS is still below its limits and has a high
                      potential to boost itsperformance. Considering the current
                      ESS, the goal should be a compression of proton pulses near
                      to 50 to 100 μs, comparableto the moderation time of
                      thermal neutrons. It will increase the peak brightness for
                      thermal neutrons up to about a factor 50 and forthermal
                      instruments, sufficiently high resolution can be achieved
                      even without pulse shaping choppers. Including cold
                      instruments,on average there is an order of magnitude
                      increase in performance with some appealing options for the
                      instrument suite. Theupgrade of the ESS linac with a
                      compressor ring is part of the neutrino physics proposal of
                      the ESS, ESSnuSB. Its use for neutronproduction with 1.2 μs
                      proton-pulses at 5MW will cause likely unacceptable
                      thermomechanical shocks in the spallation target.Alternative
                      proposals for slow extraction from the accumulator ring are
                      less challenging for the target but more so for
                      theaccumulator extraction zone for which too high
                      irradiation must be avoided. Clearly, the design of such
                      options to generatecompressed proton pulses of medium
                      duration is strongly motivated by gaining the ultimate
                      possible neutron peak brightness totap the full high
                      potential of the ESS.},
