Systems, apparatuses, and methods are provided for removing heat from a reticle. An example method can include generating, by a cooling controller, a cooling control signal based on timing data for a projection of a patterned radiation beam formed by illuminating an exposed area on a reticle supported by a reticle table, absorption data for the exposed area, and a target heat transfer rate. The cooling control signal can instruct a reticle cooling apparatus to actuate actuators to modify a distance between the reticle and a roof of the reticle cooling apparatus. The method can further include modifying, by the actuators based on the cooling control signal, the distance between the reticle and the roof to modify a heat transfer rate associated with a removal of heat from the reticle towards the target heat transfer rate.
