title: [Ionization chambers with preamplifiers for X-ray exposure metering systems].
abstract: Ionization chambers with preamplifiers available from SpektrAp, Ltd., are described. The ionization chambers are intended for use in X-ray automatic exposure systems of diagnostic X-ray apparatuses. The ionization chambers provide automated matching of their sensitivity to the sensitivity of modern intensifying screens. The preamplifier provides direct integration of the ionization chamber current. It can operate within the entire dose rate range of the roentgenographic mode and meets the requirements of modern diagnostic X-ray detectors to the dose range. Special techniques for increasing the noise immunity of preamplifiers are described. Performance specifications of the ionization chambers and preamplifiers are given.
