Temperature control design for a high-resolution gamma ray tomography detector

Bieberle, A.; Schleicher, E.; Hampel, U.

In this paper a thermal control design for a high-resolution gamma ray computed tomography (CT) detector is presented. It accounts for the generation of heat produced by active electronic components as well as heat transfer from external heat sources. The development and implementation of this feature was motivated by stringent requirements for measurement accuracy at thermal hydraulic test facilities where ambient thermal conditions are constantly changing. As a first step the thermal behaviour of the existing tomography detector was analysed, critical components were identified and different approaches for heat removal were tested. Eventually, an improved thermal detector design was elaborated and a controlled active cooling system implemented. Performance tests proved its effectiveness and accuracy improvement.
