Abstract: This article describes the performance and the architecture of the power supply system for the Tracker detector in the AMS-02 experiment. Qualification tests results on assembled crates will be also presented. The AMS-02 experiment will be installed in the International Space Station (ISS); it will measure the cosmic ray spectrum from 0.5GeV up to several TeV looking for anti-matter, dark matter and strange quark matter. A preliminary version of the experiment has successfully flown in 1998 on the STS-91 space shuttle flight. The power supply system for the Tracker detector was used as a guideline for the other power supply systems in the experiment. [Copyright &y& Elsevier]

Abstract: This article describes the control electronics for the silicon tracker cooling system in the AMS-02 apparatus. It also contains a brief description of the cooling system itself necessary for the description of the electronics. The tracker cooling system includes a set of various sensors and actuators which are necessary for bringing the tracker detector to a uniform temperature at which it can operate correctly. In order to test the system performing the various qualification activities we have built also an Electronic Ground support equipment (EGSE). The EGSE should simulate the behaviour of all sensors and actuators previously mentioned. [Copyright &y& Elsevier]
