| 内容記述 | We report the validation results of liquid lithium target stability for an intense fusion neutron source currently being planned for the International Fusion Materials Irradiation Facility (IFMIF), the Advanced Fusion Neutron Source (A-FNS), or the DEMO Oriented Neutron Source (DONES).The thickness variation of a Li target must be suppressed to within 1 mm inside a deuteron beam footprint to maintain the integrity of the Li target and to guarantee the desired level of neutron flux. We achieve a stable Li target with an average thickness variation of just 0.17 mm inside the beam footprint under IFMIF conditions (target speed: 15 m/s; vacuum pressure: 10−3 Pa; Li temperature: 250 °C). Moreover, the mean and maximum wave amplitudes are found to be 0.26 mm and 1.46 mm, respectively, at the beam center under such conditions, and hence, small enough compared to the requirements. Finally, the Li target is operated for an extended period (~1,000 h) and it is found that the target’s stability remains unchanged during the entire subject period. This finding is regarded as an appreciable step toward the realization of IFMIF and the potential use of relevant neutron sources such as A-FNS and DONES. | |||||
