Combustor head of a gas turbine

The invention relates to a bulkhead of a gas turbine with a damping volume (207) enclosing boundary consisting of a combustion chamber remote from boundary (206) and a combustion chamber side boundary (210), characterized in that the combustion chamber side boundary (210) in the form of a perforated wall is formed (210) in the edge region of the combustion chamber side boundary (210) by recesses (203) in the boundary (206) cooling air can be guided to the bennkammerseitige boundary (210), that the cooling air which flows along the combustion chamber side boundary (210) , intersects the cooling air flow through the perforated wall (210) is separated from it by the walls and does not mix with it.
