The first version of a positron converter target will be designed to distribute the heat load by rotating the tungsten target.
Calculate for 1 mm and 2 mm thick Tungsten
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.
- IAC beamline pressure =
- Torr
