Electro-optic sensor for static fields
Electro-optic sensor for static fields
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...

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. |
