An evaluation of the behavior of three large cathode area photo-multiplier tubes, Hamamatsu R5912 Mod and R5912-02 Mod, and ETL 9357 KFLB, was carried out both at room temperature and immersed in liquid nitrogen, at a temperature of 77K. The main electrical and optical features of the devices were studied: signal shape, photo-cathode response uniformity, gain, linearity and dark count rate. An evaluation of the quantum efficiency was also made in the vacuum ultraviolet light region.

Abstract
An evaluation of the behavior of three large cathode area photo-multiplier tubes, Hamamatsu R5912 Mod and R5912-02 Mod, and ETL 9357 KFLB, was carried out both at room temperature and immersed in liquid nitrogen, at a temperature of 77K. The main electrical and optical features of the devices were studied: signal shape, photo-cathode response uniformity, gain, linearity and dark count rate. An evaluation of the quantum efficiency was also made in the vacuum ultraviolet light region.
