Abstract : The use of neutron sensitive ionization chambers for neutron flux measurement in nuclear reactors is discussed along with the limitation in neutron detection range because of the gamma ray background in which the chamber must operate. Means of extending this range are also discussed and a new type of compensated ionization chamber is described. The compensation adjustment of this new chamber is made electrically rather than mechanically as in prior compensated chambers. The extension in neutron detection range over that of an uncompensated chamber is of the order of two decades. Frequent adjustment of the compensation is not necessary since the drift is small over a long period of time.
