This report describes the specific features of the Tohoku Charge Spectrometer(TOHOKU CS)which has been constructed for the study of chemical effects of the nuclear transformations in gases, especially of the charge distribution of the residual atoms and of ion-molecule reactions in order to elucidate the primary and elemental stages in hot-atom chemistry. The facility is available for a chargespectrometer with a large source volume and a double mass spectrometer connected in perpendicular. Ions can be produced by the electron impact, X-ray irradiation or nuclear decay processes in the source volume. Charge spectrum of the residual atom after the Auger process of the nuclear decay can be measured through the first stage mass spectrometer, and products of ion-molecule reactions in the reaction chamber can be separated through the second mass spectrometer and detected by an aid of a16stages Cu-Be electron multiplier. Pulse countings are applicable in the both cases as well as direct current recordings to estimate the charged atoms or the fragment distribution. The specific availabilities of this facility are shown in some typical results by the preliminary experiments.
