Development of a high-heat-load compact photon absorber of the SPring-8 diagnostics beamline II (BL05SS), which can accept the power of 19 kW from a multi-pole wiggler, is presented. In order to make the whole system compact, the scheme which inserts two water-cooled absorber blocks made of Glidcop with a different tilt angle of surface into the photon beam axis in tandem has been adopted. When the absorber system was installed in the frontend of BL05SS and exposed to synchrotron radiation from an insertion device, the stainless steel chamber of the rear absorber block was heated rapidly by irradiation of the scattered X-rays from the absorber surface. A water-cooled absorber chamber made of oxygen-free high conductivity copper has been newly developed and the temperature rise of the chamber was successfully suppressed.
