in-situ <sup>3</sup>He neutron spin filters at JCNS, status and updates Open
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 opera…

Towards wide-angle neutron polarization analysis with a 3He spin filter for TOPAS and NEAT: Testing magic PASTIS on V20 at HZB Open
An XYZ polarization analysis solution has been developed for the new thermal time-of-flight spectrometer TOPAS [1], to be operated in the coming east neutron guide hall at the MLZ. This prototype is currently being prepared to use on NEAT …

An ultra-compact in-situ<sup>3</sup>He polarizer for high Q-range SANS: on-beam test and future upgrades Open
We present an ultra-compact 3He polarizer to be used as a polarization analyzer for separation of incoherent background for soft matter research. The 3He will be polarized in-situ within a very compact, 18 cm long, magnetic cavity that can…

First result from the magic-PASTIS using large<sup>3</sup>He SEOP-polarized GE180 doughnut cell Open
We report on the first results of the newly proposed and prototyped PASTIS coil set, enabling for XYZ polarization analysis on the future thermal time-of flight spectrometers. Our setup uses a wide-angle banana shaped 3He Neutron Spin Filt…

SEOP polarized<sup>3</sup>He Neutron Spin Filters for the JCNS user program Open
Over the past several years the JCNS has been developing in-house applications for neutron polarization analysis (PA). These methods include PA for separation of incoherent from coherent scattering in soft matter studies (SANS), and online…
