Abstract
Gas in the inner cores of rich clusters that contain central radio sou rces may be permeated by a high flux of energetic protons. Heating by these protons is likely to play a significant role in the thermal bala nce of the gas, thereby reducing the inferred cooling and mass accreti on rates. This is shown to be the case in the radio halo region of NGC 1275 in the Perseus cluster.
