Abstract
A system for receiving energy from an electromagnetic energy beam, and for transferring the received energy to a working fluid as thermal energy, comprises a heat exchanger body that defines a path for the working fluid. The heat exchanger body comprising a ceramic matrix composite (CMC) material. A method for configuring a heat exchanger for receiving energy from an electromagnetic energy beam, and for transferring the received energy to a working fluid as thermal energy, includes providing a heat exchanger body, the heat exchanger body comprising a ceramic matrix composite (CMC) material, the CMC material comprising a SiC matrix. The method also includes introducing a concentration of dopant into the SiC matrix, wherein the dopant is selected to facilitate absorption of energy from the electromagnetic energy beam, and wherein the concentration is suitable to achieve a desired rate of energy absorption from the electromagnetic energy beam.
