      abstract     = {At JCNS we develop a technical design for a future high
                      brilliance neutron source HBS. The very compact design of
                      the neutronsource allows to extract larger phase space
                      volumes from the neutron moderators as compared to existing
                      facilities, where theminimum distance between the moderator
                      and extraction system and/or first choppers poses a
                      significant constraint. In thispresentation we discuss a
                      concept for a compact hybrid chopper spectrometer, that
                      images the neutron source via a large crystalmonochromator
                      onto the sample. The monochromator provides a narrow
                      wavelength resolution also for short wavelength, whichis
                      difficult to realize at long pulse and continuous neutron
                      sources. The secondary wavelength is resolved by a chopper
                      close tothe sample and the time-of-flight to the detector,
                      leading to the name “Crystof” for this spectrometer. The
                      instrument is optimizedfor neutron energy loss scattering in
                      the energy range between 10 and 100 meV resulting in a
                      compact secondary spectrometerthat allows large solid angle
                      coverage at acceptable cost for the detector system. We will
                      compare the performance of such aconcept to existing thermal
                      time of flight spectrometers. This work is part of the
                      collaboration within ELENA and LENS on thedevelopment of
