The Pixel detector of the ATLAS experiment at the CERN LHC will contain around 1750 individual detector modules. The high power density of the electronics - requiring an extremely efficient cooling system - together with the harsh radiation environment constrains the desgin of the detector control system. An evaporative fluorocarbon system has been chosen to cool the detector. Since irradiated sensors can be irraparably damaged by heating up, great emphasis has been placed on the safety of the connections between the cooling system and the power supplies. An interlock box has been developed for this purpose, and has been tested in prototype form with the evaporative cooling system. We report on the status of the evaporative cooling system, on the plans for the detector control system and upon the perforamnce and irradiation tests of the interlock box.
