HRRL Positron Rotating W Target
The first version of a positron converter target will be designed to distribute the heat load by rotating the tungsten target.
Properties of Tungsten
Melting Point =
Heat Capacity =
Heat loss due to radiation ( \sigma T^4)
Tungsten Temperature as a function of heat load
The Tungsten heats up when an MeV energy electron impinges its surface. The imperfect vacuum inside the beam pipe does allow some radiative cooling.
