Each undulator is 3 meter and the drift space between two undulator is 3.991m. The synchrotron radiation is propagating in the longitudinal direction and will result in a serious heat load problem for undualtor downstream. The magnet array of undualtor downstream will received the synchrotron radiation of 142W from upstream bending magnet and undualtor. Heat load is a critical challenge for in-vacuum undulator in double mini-beta Y lattice and therefore details analysis in this paper.
