Status of the Radon EDM Experiment
Abstract
An experiment to measure the permanent electric dipole moment (EDM) of ^223Rn is under development at TRIUMF. The EDM of ^223Rn is expected to be enhanced by a factor of several hundred relative to ^199Hg due to effects of octupole deformation. In the first runs, the ^223Rn will be polarized by spin-exchange with laser polarized Rb and the precession frequency in combined magnetic fields will be measured using gamma-ray anisotropies detected in the large solid angle TIGRESS array of HPGe detectors. In preparation, polarization and relaxation of radon isotopes by spin exchange with laser optically pumped rubidium have been studied over the range 130^oC to 220^oC. The generation of a greater rubidium polarization in the radon spin-exchange optical pumping cells using a narrow-band diode laser is under investigation. Other preparations and the time frame for the measurements will be presented.
