Abstract
In order to limit the increased quantity of ions produced within the tube as a result of the presence of a microchannel element within the tube, getters are placed on the probable path followed by the ions under the action of potentials applied to the electrodes. The electrodes to which the getters adhere are designed in two parts or constituent elements in order to permit the supply of getters if necessary. The electrode elements are bent-back in order to serve as shields in the case of vaporizable getters.
