      abstract     = {The recent layout of the Jülich High Brilliance Neutron
                      Source (HBS) driver linac is based on short crossbar H-mode
                      (CH) cavities operated at a fixed synchronous phase. In the
                      last decades the computing power for the development of
                      linacs, available to physicists and engineers, has been
                      increased drastically. This also enabled the accelerator
                      community to finally carry out the required $R\&D$ to
                      generate further the idea of drift tube linacs with
                      alternating phase focusing (APF) beam dynamics, originally
                      proposed in the 1950s. This focusing method uses the
                      electric fields in between the drift tubes (i.e., gaps) to
                      provide subsequent transverse and longitudinal focusing to
                      the beam along multiple gaps. The beam focusing properties
                      within each gap are adjusted individually by means of the
                      synchronous phase. As a result of the alternating phase
                      focusing method, these linacs can operate completely without
                      internal magnetic lenses. The $R\&D-program$ for the high
                      brilliance neutron source HBS offered the opportunity to
                      investigate the APF concept further in order to open this
                      advanced concept for high duty-factor, high intensity hadron
                      beam acceleration. Besides, a prototype APF-interdigital
                      H-mode (IH)-cavity has been designed and is going to be
                      build and tested in the next future.},
