Abstract
A design is presented for a new type of optical module for deep-sea neutrino telescopes. The module consists of a glass pressure resistant sphere containing 31 small 3 in. photomultiplier tubes oriented so as to provide a maximal coverage in solid angle. In addition to the photomultipliers the sphere contains all the electronics for production of the high voltage and for the readout of the signals of the photomultipliers. The power consumption of the module is kept to a mere 7 W. A heat transfer system conducts the excess produced heat from the electronics to the ambient sea water. The Optical module forms a complete stand-alone detector that is connected to the outside world via a single optical fibre and two copper conductors to provide electrical power.
