The Coulomb mean-free-path of these protons is larger than the virial radius of the cluster at temperatures >2.5 keV. The resulting leakage of suprathermal particles generates a collisionless shock in neighboring voids and fills them with heat and magnetic fields. The momentum flux of suprathermal particles cannot be confined by magnetic tension at the typical field strength in the periphery of cluster halos (<<1 micro-gauss).
