Abstract
Current-voltage characteristics of a new-type ionization chamber made by a levitated battery and electrodes was measured. The electrode to be supplied with electric voltage and a battery levitates into air, and the electrode to collect ions are supported on a base by insulators, and connected to an ammeter. Potential is induced between the high-voltage electrodes levitated and a charge-collecting electrode grounded, so that ions due to rariations are collected on the charge-collecting electrode. In this method, there is no leakage current flowing from the high-voltage electrodes to the charge-collecting electrode and ammeter. Therefore, even under the condition of high humidity, it is possible to measure the ionization current continuously with high sensitivity. In the experimental results, current-voltage characteristics of this new-type ionization chamber agree well with those of the conventional ionization chamber. In addition, together with stable ionization current shown in an atmosphere with high humidity, it has been possible to measure variations of ionization current due to those of humidity.
