[en] Modification of KUR-ISOL is currently being carried out. The report describes major improvements that have been or are planned to be made. The diameter of the ionizer and filament winding largely affects the temperature. An ionizer that is small in size and gas release has been designed and constructed. Heating is achieved by automatic filament outgassing and bombardment outgassing. An ion-source power supply is designed so that these two processes can be controlled appropriately and that the power will be rapidly decreased when the vacuum deteriorates. To maintain the stability of the electron bombardment current and voltage, a stabilizing circuit is constructed which produces signals to control the power to the filament if the bonbardment current exceeds a certain limit. The newly designed power supply for the electromagnet is capable of remote control, automatic sweeping and computer control. It is equipped with a mass peak stabilizer incorporating a ratemeter. A centralized control and monitoring console is also constructed which can perform centralized control of various processes and continuous recording. Various improved measuring devices are designed which are required to construct a high-efficiency measuring system to serve for measurement of exotic nuclei. Such devices include a high-efficiency X-γ N-type HP Ge detector, high-efficiency Si(Li)-β coincidence spectrometer, four-counter goniometer and Ge multiple-counter goniometer. (Nogami, K.)
