Design features are described for an integrating ion chamber dose meter developed for radiation survey work on the Cosmotron. The complete instrument consists of a Rossi tissue equivalent chamber connected to a vibrating-reed electrometer with accessory circuits. For use as sn integrating instrument one of the high value resistors normally fitted in the head unit is removed so that the current from the ionization chamber charges the input capacity due to the chamber itself and its connections. The accessory circuit is a transistorized Schmitt trigger which operates when the voltage developed across the input capacity corresponds to the full scale value on any range of the main unit. A sketch of the circuit and a photograph of the complete instrument are included. (C.H.)
