Abstract
We built and operated a cryogenic facility for testing in liquid xenon the photomultipliers (PMTs) to be used in the electromagnetic calorimeter of the MEG experiment. In this paper we describe the working principle of the facility and we report on the characteristics measured for some PMTs.
