      abstract     = {Maintaining high levels of 3He polarization over long
                      periods of time is important for many areas of fundamental
                      and particle beam physics. Long measurement times are often
                      required in such experiments, and the data quality is a
                      function of the 3He polarization. This is the case for
                      neutron scattering, where the 3He can be used to analyze the
                      spin of a scattered neutron beam. For neutron scattering,
                      the relatively small fluxes of polarized neutrons lead to
                      experiment times longer than several days. Consequently, the
                      Jülich Centre for Neutron Science (JCNS) is developing
                      spin-exchange optical pumping (SEOP) systems capable of
                      polarizing the 3He gas in place on a typical neutron
                      instrument. With the polarizer we have constructed, a very
                      high level of 3He polarization of $80.4\%±1.5\%$ was
                      obtained and maintained with good time stability. Having
                      such high levels of polarization that are stable over time
                      will reduce the measurement times for such experiments and
                      eliminate time-dependent data corrections.},
