Description
Computational Fluid Dynamics (CFD) has been used to design a very high-power rotating tungsten target to produce a positron beam. The positrons will be produced by a primary 1 mA electron beam with energy 120 MeV impinging on a rotating tungsten wheel through bremsstrahlung. The W target will be instrumented with water cooling to remove the estimated 17 kW of heat deposited by the primary electron beam in it [1]. The target will be central to accomplishing a rich experimental program using a positron beam at Jefferson Lab. In this contribution, I will present the status of the CFD-driven design of the target and the path towards a production positron target.
