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. 001018150 536__ $$0G:(DE-HGF)POF4-6G4$$a6G4 - Jülich Centre for Neutron Research (JCNS) (FZJ) (POF4-6G4)$$cPOF4-6G4$$fPOF IV$$x0 001018150 536__ $$0G:(DE-HGF)POF4-632$$a632 - Materials – Quantum, Complex and Functional Materials (POF4-632)$$cPOF4-632$$fPOF IV$$x1 001018150 536__ $$0G:(DE-HGF)POF4-5212$$a5212 - Emergent Quantum Phenomena (POF4-521)$$cPOF4-521$$fPOF IV$$x2 001018150 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 001018150 65027 $$0V:(DE-MLZ)SciArea-220$$2V:(DE-HGF)$$aInstrument and Method Development$$x0 001018150 65017 $$0V:(DE-MLZ)GC-2002-2016$$2V:(DE-HGF)$$aInstrument and Method Development$$x0 001018150 693__ $$0EXP:(DE-MLZ)KWS1-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)KWS1-20140101$$6EXP:(DE-MLZ)NL3b-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz $$eKWS-1: Small angle scattering diffractometer$$fNL3b$$x0 001018150 693__ $$0EXP:(DE-MLZ)POLI-HEIDI-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)POLI-HEIDI-20140101$$6EXP:(DE-MLZ)SR9a-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz $$ePOLI: Polarized hot neutron diffractometer$$fSR9a$$x1 001018150 7001_ $$0P:(DE-Juel1)144963$$aSalhi, Z.$$b1$$ufzj 001018150 7001_ $$0P:(DE-Juel1)144382$$aFeoktystov, A.$$b2$$ufzj 001018150 7001_ $$0P:(DE-HGF)0$$aBannenberg, L.
