      abstract     = {A sensor has been developed for low frequency and DC
                      electric fields E. The device is capable of measuring fields
                      with Delta-E = 4 (1) V/cm resolution. It is based on a Y-cut
                      Z-propagation lithium niobate electro-optic crystal. For a
                      particular commercially available bare crystal, we achieved
                      an in air time constant $tau_c(air)$ = 6.4(1.8) h for the
                      decay of the electro-optic signal. This enables field
                      monitoring for several hours. As an application, we
                      demonstrated that a constant electric field Eext = 640 V/cm
                      applied via external electrodes to a particular spherical
                      glass container holding an Xe/He gas mixture decays inside
                      this cell with a time constant tau-E-glass = 2.5(5) h. This
                      is sufficient for the needs of experiments searching for a
                      permanent electric dipole moment in 129Xe. An integrated
                      electric field sensor has been constructed which is coupled
                      to a light source and light detectors via optical fibers.
                      The sensor head does not contain any electrically conducting
                      material.},
