We recently carried out the 3CR snapshot survey designed to complete the X-ray coverage of all extragalactic radio sources listed in the Third Cambridge catalog (3CR). Here we request XMM-Newton follow up observations of two low-redshift radio galaxies: 3CR403.1 and 3CR430 harbored in galaxy clusters. We aim at estimating spectral parameters of both galaxy clusters surrounding these FRII radio galaxies and measure the extension of the galaxy cluster tracing the diffuse X-ray emission due to the intergalactic medium (IGM) in comparison with the detected radio structures at virgul150 MHz. We will also be able to compare galaxy cluster properties of both our targets with those of FRIs at similar z crucial to test results recently achieved with our statistical analyses. [truncated!
