Description
The Mu2e experiment at Fermilab plans to use a a radiation cooled production target to generate pions from an incoming 8kW proton beam. Radiative cooling results in a high surface temperature, requiring a high-Z, refractory metals target material due to its high melting point, high tensile strength and low thermal expansion coefficient. Tungsten is the material of choice for this application. Design of the target cartridge and remote handling machine has been carried out. Challenges of the radiation cooled design and development have focused on emissivity, creep, oxidation, radiation damage resistance, together with alignment stability across a wide temperature range. I will discuss the status of the Mu2e target design and development, including discussion of the emissivity optimization approaches, such as coatings, surface roughness, and fabrication strategy.
