  abstract     = {{The Hard X-ray Imaging Beamline, being constructed at High Energy Photon Source (HEPS), will use three types of insertion devices in different operating modes, including CPMU, IAW73 and Mango Wiggler. Therefore, the front end of this beamline will receive synchrotron radiation with different distribution, including peak power density and receiving angle. To adequate diverse power distribution with a general geometry, a novel design of front end slits is development. Its absorbers are reasonably designed into segmented surfaces with different grazing angles according to the power density distribution of synchrotron radiation. Through this design, the slits can withstand thermal loads with a peak power density of 414kW/mrad2 and a maximum section of 30×30mm. Detailed thermal analyses of the absorbers under various operating modes are implemented to verify its safety performance under high heat loads. This new type of slits not only can adjust the aperture according to the needs of different operating modes, but also effectively shorten the length of the absorbers in the limited space of the front end.}},
