A discussion on linear and box-type multiplier phototubes is presented. Various aspects of dynode geometry and front end design of the Du Mont linear type multiplier structure in regard to transit time and transit-time spread are discussed. Several methods of operation of the front end of a multiplier phototube are considered in order to determine the optimum conditions for collection efficiency and transit-time spread. The mechanical requirements of various linear multiplier phototube types are discussed briefly. The development of linear tube types has come about as a result of an increasing demand for fast tubes capable of delivering high peak pulse output currents.
