Abstract :
The alignment systems required for the PHENIX muon tracking chamber system will be described. These systems include the system that has been developed to accurately electro-etch cathode strip foils with respect to external fiducial marks to a 25 μm accuracy, as well as the system that is being developed to measure the relative alignment of three stations of chambers spanning 4.5 meters, to an accuracy of 25 μm
