We propose a 100ks observation of the radio-loud quasar PKS 1229-02 at z=1.043 in order to study the surrounding diffuse X-ray emission revealed in an 18 ks archival Chandra image. The size and spectrum of the diffuse emission coupled with high Faraday rotation in the radio band strongly point to it being an X-ray luminous cool core cluster of galaxies. Such clusters are rarely found at high redshift, possibly because the central black hole is very active. The proposed data will give valuable information on the origin of the cool core phenomenon, which is central to radio mode AGN feedback.
