This paper deals with recent developments of power absorbing devices such as beam d~umps, slits, and collimators. A brief discussion is given cf the heat transfer experiments that have been conducted at the Stanford Linear Acceleretor Ctlter to establish dtaign heat flux collaitions for the various materials tc be used for the power s7 sorbing devices. Design concepts of a 2.2 MW, 11 t; 25 GeV beam dump, as presently being built at SLAC, are also discussed. Finally, there is a typical analysis which leads to the design of a collimator, with emphasis on beam definition, heat transfer, thermal stress development and material selection
