Paper Abstract
In SPring-8 beamline for insertion devices heat load problems of the optics become serious. Efficient cooling methods must be improved to make use of the original photon characteristics. Here we indicate some simple and analytical calculations for monochromator crystal. Angle distortions due to the thermal deformation for Si crystal are indicated by using simple formulas. Critical heat flux for liquid nitrogen cooling is estimated to be a few W/mm2. The thermal conductance and the loss of head are calculated as a function of fin number in the cooling channel considering the fin efficiency. The possibility of using a diamond crystal for the undulator beamline is also discussed.
