      abstract     = {The JCNS has been developing and using in-situ polarized
                      neutron spin filters for many applications. The system used
                      for analysis on MARIA and polarization for TOPAS were
                      completed about 10 years ago with the MARIA system in
                      standard operation for users and the TOPAS system employed
                      for a long measurement on the POLI instrument. In the
                      meantime we are progressing on several new in-situ
                      polarizers based on these first two but with additional
                      innovations. The KWS-1 analyzer device which was recently
                      used in tests at TU Delft and ISIS is essentially a
                      $50\%-sized$ copy of the MARIA device. The two devices in
                      construction for polarization and analysis on POLI for hot
                      neutrons feature magic-boxes with angled plates on both the
                      entrance and exit sides to minimize overal length and the
                      polarizer device will employ an additional passive magnetic
                      shield of soft iron so that it can operate inside the stray
                      field area of a 8-T vertical (compensated) sample magnet. We
                      will summarize the current status of our 3He neutron spin
                      filters and provide extra focus on the technical aspects and
                      measured performance characteristics of the new devices for
                      KWS-1 and POLI in particular.},
