Abstract
The array camera and spectrometer PACS to be flown aboard the European 3.5 m infrared space telescope FIRST will apply a cold focal plane chopper. Its development has to meet ambitious goals, such as large chopper throws, high operational accuracy in several modes, very low heat dissipation in the cryogenic environment, sufficient rigidity to meet the ARIANE5 launch conditions and a long lifetime thereafter. The prototype development of such a chopper and test results under cryovacuum conditions are reported here.
