FARADAY-ROTATION IN COOLING FLOW CLUSTERS OF GALAXIES .1. RADIO AND X-RAY OBSERVATIONS OF ABELL 1795

We present new, multiwavelength Very Large Array observations of the radio galaxy 1346+268 in the center of cooling flow cluster Abell 1795. With the high resolution (0.''6) observations, the radio source is generally 10% to 30% polarized. We find large Faraday rotation measures, exceeding 3000 rad m-2 in places. Using the x-ray images of Abell 1795 from the Einstein database, we have modeled the distribution of the hot, x-ray emitting gas. The large rotation measures could be induced by the magneto-ionized intracluster medium. The field must be typically > 20 muG near the cluster center. If the field is not ordered, it may have a similar energy density as the thermal energy density in the x-ray emitting gas.
