The proposed work addresses energy transfer from a specific                     device, an x-ray tube, whose performance is limited by the                      magnitude of cooling.  A composite microfabricated device is                    proposed to achieve the necessary heat transfer.  This research                 has promise for the proposed device and will have general                       application in numerous other areas.                                                                                                                            The work seeks to establish the feasibility of microfabricated                  heatpipes to improve the heat transfer from x-ray tube anodes.                  The objective of this proposal is to define the range of wall                   materials, dimensions, and working fluids that provide optimum                  performance in various anode operating regimes.  The proposed                   effort will develop a comprehensive device model, validate the                  model experimentally, and then optimize the design of the device.
