N2 - Glass cells play an important role in polarized 3He neutron spin filters. To evaluate the scattering and absorption contribution from glass cells during neutron scattering experiments, we measured small-angle scattering and neutron transmission in GE180 and other glasses. The small-angle neutron scattering measurements revealed that the glasses used for 3He spin filters have acceptably lower scattering: dΣ(Q)/dΩ=47×10 -4 cm-1 at Q=0.030.12 Å-1. The transmission measurement was performed at J-PARC. Neutron transmission of about 92% through empty GE180 cells was observed over a wide wavelength range 0.0147.0 Å. To pursue the possibility of being a structural influence on 3He spin relaxation in GE180 glass cells, we performed precise X-ray diffraction measurement using synchrotron radiation at SPring-8. From these measurements, a structural difference was observed among GE180 glasses with different thermal treatments.
