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.},
