However, for the case a horizontal de-flection mirror, the unilateral cooling method is usually adopted, resulting in some changes in the structure of the mirror. In this paper, a first mirror horizontally deflect-ing in Hefei advanced light source (HALF) are taken as examples to introduce the optimization method to achieve ultra-low meridian slope error of the first hori-zontal deflection mirror. The results show that this opti-mization method provides a rapid design mean to design the cooling scheme of the horizontally deflecting mirror based on the eInGa bath.
