Introduction
============

Understanding how a powerful radio galaxy interacts with a poor environment is important in exploring the impact of radio galaxies on the properties of the group population. The most powerful class of jet-driven AGN outbursts that we know of are the FRII radio galaxies [@fr74]. X-ray observations of some of these objects suggest that the energy input from the expanding radio galaxy can be similar to the binding energy of the local intergalactic medium (e.g. @kbhecwm07, @hck07); thus it is clear that in principle those sources will have a profound effect on their environments over their lifetimes.

The radio lobes in FRII radio galaxies are the result of the interactions between the relativistic electrons that have passed up the jet and the external medium, where the electrons gain energy at the jet termination shocks and expand out into the external medium [@s74]. It has been known for many years that the inflation of these lobes should affect the surrounding intergalactic medium (IGM). Even when the lobes
